dcc0a33e 6@section testmanual_intro Introduction
72b7576f 7
504a8968 8This document provides OCCT developers and contributors with an overview and practical guidelines for work with OCCT automatic testing system.
9
6d368502 10Reading the Introduction should be sufficient for developers to use the test system to control non-regression of the modifications they implement in OCCT. Other sections provide a more in-depth description of the test system, required for modifying the tests and adding new test cases.
72b7576f 11
dcc0a33e 12@subsection testmanual_intro_basic Basic Information
72b7576f 13
9d99d3c1 14OCCT automatic testing system is organized around @ref occt_user_guides__test_harness "DRAW Test Harness", a console application based on Tcl (a scripting language) interpreter extended by OCCT-related commands.
e5bd0d98 15
504a8968 16Standard OCCT tests are included with OCCT sources and are located in subdirectory *tests* of the OCCT root folder. Other test folders can be included in the test system, e.g. for testing applications based on OCCT.
e5bd0d98 17
504a8968 18The tests are organized in three levels:
72b7576f 19
504a8968 20 * Group: a group of related test grids, usually testing a particular OCCT functionality (e.g. blend);
21 * Grid: a set of test cases within a group, usually aimed at testing some particular aspect or mode of execution of the relevant functionality (e.g. buildevol);
22 * Test case: a script implementing an individual test (e.g. K4).
23
67d7f07f 24See @ref testmanual_5_1 "Test Groups" chapter for the current list of available test groups and grids.
72b7576f 25
d3013f55 26@note Many tests involve data files (typically CAD models) which are located separately and (except a few) are not included with OCCT code.
27These tests will be skipped if data files are not available.
72b7576f 28
29@subsection testmanual_1_2 Intended Use of Automatic Tests
30
31Each modification made in OCCT code must be checked for non-regression
6d368502 32by running the whole set of tests. The developer who makes the modification
504a8968 33is responsible for running and ensuring non-regression for the tests available to him.
34
6d368502 35Note that many tests are based on data files that are confidential and thus available only at OPEN CASCADE.
36The official certification testing of each change before its integration to master branch of official OCCT Git repository (and finally to the official release) is performed by OPEN CASCADE to ensure non-regression on all existing test cases and supported platforms.
504a8968 37
38Each new non-trivial modification (improvement, bug fix, new feature) in OCCT should be accompanied by a relevant test case suitable for verifying that modification. This test case is to be added by the developer who provides the modification.
72b7576f 39
504a8968 40If a modification affects the result of an existing test case, either the modification should be corrected (if it causes regression) or the affected test cases should be updated to account for the modification.
72b7576f 41
504a8968 42The modifications made in the OCCT code and related test scripts should be included in the same integration to the master branch.
72b7576f 43
44@subsection testmanual_1_3 Quick Start
45
46@subsubsection testmanual_1_3_1 Setup
47
504a8968 48Before running tests, make sure to define environment variable *CSF_TestDataPath* pointing to the directory containing test data files.
504a8968 49
50For this it is recommended to add a file *DrawAppliInit* in the directory which is current at the moment of starting DRAWEXE (normally it is OCCT root directory, <i>$CASROOT </i>). This file is evaluated automatically at the DRAW start.
51
52Example (Windows)
72b7576f 53
6d368502 54~~~~~{.tcl}
504a8968 55set env(CSF_TestDataPath) $env(CSF_TestDataPath)\;d:/occt/test-data
6d368502 56~~~~~
504a8968 57
504a8968 58Note that variable *CSF_TestDataPath* is set to default value at DRAW start, pointing at the folder <i>$CASROOT/data</i>.
87f42a3f 59In this example, subdirectory <i>d:/occt/test-data</i> is added to this path. Similar code could be used on Linux and Mac OS X except that on non-Windows platforms colon ":" should be used as path separator instead of semicolon ";".
72b7576f 60
936f43da 61All tests are run from DRAW command prompt (run *draw.bat* or *draw.sh* to start it).
72b7576f 62
63@subsubsection testmanual_1_3_2 Running Tests
64
504a8968 65To run all tests, type command *testgrid*
72b7576f 66
67Example:
68
504a8968 69~~~~~
70Draw[]> testgrid
71~~~~~
72b7576f 72
ae3eaf7b 73To run only a subset of test cases, give masks for group, grid, and test case names to be executed.
74Each argument is a list of file masks separated with commas or spaces; by default "*" is assumed.
72b7576f 75
504a8968 76Example:
72b7576f 77
504a8968 78~~~~~
87f42a3f 79Draw[]> testgrid bugs caf,moddata*,xde
504a8968 80~~~~~
72b7576f 81
72b7576f 82As the tests progress, the result of each test case is reported.
504a8968 83At the end of the log a summary of test cases is output,
84including the list of detected regressions and improvements, if any.
72b7576f 85
86
504a8968 87Example:
88
72b7576f 89~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
90 Tests summary
91
92 CASE 3rdparty export A1: OK
93 ...
94 CASE pipe standard B1: BAD (known problem)
95 CASE pipe standard C1: OK
96 No regressions
97 Total cases: 208 BAD, 31 SKIPPED, 3 IMPROVEMENT, 1791 OK
98 Elapsed time: 1 Hours 14 Minutes 33.7384512019 Seconds
99 Detailed logs are saved in D:/occt/results_2012-06-04T0919
100~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
101
dcc0a33e 102The tests are considered as non-regressive if only OK, BAD (i.e. known problem), and SKIPPED (i.e. not executed, typically because of lack of a data file) statuses are reported. See @ref testmanual_details_results "Interpretation of test results" for details.
72b7576f 103
936f43da 104The results and detailed logs of the tests are saved by default to a new subdirectory of the subdirectory *results* in the current folder, whose name is generated automatically using the current date and time, prefixed by Git branch name (if Git is available and current sources are managed by Git).
3f812249 105If necessary, a non-default output directory can be specified using option <i> -outdir</i> followed by a path to the directory. This directory should be new or empty; use option <i>-overwrite</i> to allow writing results in the existing non-empty directory.
72b7576f 106
504a8968 107Example:
108~~~~~
87f42a3f 109Draw[]> testgrid -outdir d:/occt/last_results -overwrite
504a8968 110~~~~~
ae3eaf7b 111In the output directory, a cumulative HTML report <i>summary.html</i> provides links to reports on each test case. An additional report in JUnit-style XML format can be output for use in Jenkins or other continuous integration system.
504a8968 112
dcb359e0 113To re-run the test cases, which were detected as regressions on the previous run, option <i>-regress dirname</i> should be used.
114<i>dirname</i> is a path to the directory containing the results of the previous run. Only the test cases with *FAILED* and *IMPROVEMENT* statuses will be tested.
b502ddc1 115
116Example:
117~~~~~
118Draw[]> testgrid -regress d:/occt/last_results
119~~~~~
120
936f43da 121Type <i>help testgrid</i> in DRAW prompt to get help on options supported by *testgrid* command:
72b7576f 122
504a8968 123~~~~~
124Draw[3]> help testgrid
125testgrid: Run all tests, or specified group, or one grid
87f42a3f 126 Use: testgrid [groupmask [gridmask [casemask]]] [options...]
504a8968 127 Allowed options are:
128 -parallel N: run N parallel processes (default is number of CPUs, 0 to disable)
129 -refresh N: save summary logs every N seconds (default 60, minimal 1, 0 to disable)
130 -outdir dirname: set log directory (should be empty or non-existing)
131 -overwrite: force writing logs in existing non-empty directory
132 -xml filename: write XML report for Jenkins (in JUnit-like format)
936f43da 133 -beep: play sound signal at the end of the tests
dcb359e0 134 -regress dirname: re-run only a set of tests that have been detected as regressions on the previous run.
135 Here "dirname" is a path to the directory containing the results of the previous run.
136 Groups, grids, and test cases to be executed can be specified by the list of file
137 masks separated by spaces or commas; default is all (*).
504a8968 138~~~~~
72b7576f 139
504a8968 140@subsubsection testmanual_1_3_3 Running a Single Test
141
87f42a3f 142To run a single test, type command *test* followed by names of group, grid, and test case.
72b7576f 143
144Example:
145
146~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
147 Draw[1]> test blend simple A1
148 CASE blend simple A1: OK
149 Draw[2]>
150~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
151
504a8968 152Note that normally an intermediate output of the script is not shown. The detailed log of the test can be obtained after the test execution by running command <i>"dlog get"</i>.
153
154To see intermediate commands and their output during the test execution, add one more argument
155<i>"echo"</i> at the end of the command line. Note that with this option the log is not collected and summary is not produced.
156
ae3eaf7b 157Type <i>help test</i> in DRAW prompt to get help on options supported by *test* command:
936f43da 158
159~~~~~
160Draw[3]> help test
161test: Run specified test case
162 Use: test group grid casename [options...]
163 Allowed options are:
164 -echo: all commands and results are echoed immediately,
165 but log is not saved and summary is not produced
166 It is also possible to use "1" instead of "-echo"
167 If echo is OFF, log is stored in memory and only summary
168 is output (the log can be obtained with command "dlog get")
169 -outfile filename: set log file (should be non-existing),
170 it is possible to save log file in text file or
171 in html file(with snapshot), for that "filename"
172 should have ".html" extension
173 -overwrite: force writing log in existing file
174 -beep: play sound signal at the end of the test
175 -errors: show all lines from the log report that are recognized as errors
176 This key will be ignored if the "-echo" key is already set.

dcc0a33e 179@subsubsection testmanual_intro_quick_create Creating a New Test
504a8968 180
67d7f07f 181The detailed rules of creation of new tests are given in @ref testmanual_3 "Creation and modification of tests" chapter. The following short description covers the most typical situations:
504a8968 182
6d368502 183Use prefix <i>bug</i> followed by Mantis issue ID and, if necessary, additional suffixes, for naming the test script, data files, and DRAW commands specific for this test case.
504a8968 184
6d368502 1851. If the test requires C++ code, add it as new DRAW command(s) in one of files in *QABugs* package.
67d7f07f 1862. Add script(s) for the test case in the subfolder corresponding to the relevant OCCT module of the group *bugs* <i>($CASROOT/tests/bugs)</i>. See @ref testmanual_5_2 "the correspondence map".
504a8968 1873. In the test script:
188 * Load all necessary DRAW modules by command *pload*.
189 * Use command *locate_data_file* to get a path to data files used by test script. (Make sure to have this command not inside catch statement if it is used.)
251a7984 190 * Use DRAW commands to reproduce the tested situation.
191 * Make sure that in case of failure the test produces a message containing word "Error" or other recognized by the test system as error (add new error patterns in file parse.rules if necessary).
192 * If the test case reports error due to an existing problem and the fix is not available, add @ref testmanual_3_6 "TODO" statement for each error to mark it as a known problem. The TODO statements must be specific so as to match the actually generated messages but not all similar errors.
193 * To check expected output which should be obtained as the test result, add @ref testmanual_3_7 "REQUIRED" statement for each line of output to mark it as required.
194 * If the test case produces error messages (contained in parse.rules), which are expected in that test and should not be considered as its failure (e.g. test for *checkshape* command), add REQUIRED statement for each error to mark it as required output.
8ee9c2f4 1954. To check whether the data files needed for the test are already present in the database, use DRAW command *testfile* (see below).
196 If the data file is already present, use it for new test instead of adding a duplicate.
197 If the data file(s) are not yet present in the test database, put them to some folder and add it to the environment variable *CSF_TestDataPath* to be found by the test system.
198 Information on where the data files can be accessed by OCC team for putting to official database should be provided in comment to Mantis issue, clearly indicating how names of the files used by the test script match the actual names of the files.
199 The simplest way is to attach the data files to the Mantis issue, with the same names as used by the test script.
251a7984 2005. Check that the test case runs as expected (test for fix: OK with the fix, FAILED without the fix; test for existing problem: BAD), and integrate it to the Git branch created for the issue.
504a8968 201
202Example:
203
204* Added files:

72b7576f 224
8ee9c2f4 225DRAW command testfile should be used to check the data files being used by the test for possible duplication of content or names.
226The command accepts list of paths to files being checked as single argument, and will give conclusion on each of the files, for instance:
227
228~~~~~
229Draw[1]> testfile [glob /my/data/path/bug12345*]

72b7576f 252@section testmanual_2 Organization of Test Scripts
253
254@subsection testmanual_2_1 General Layout
255
256Standard OCCT tests are located in subdirectory tests of the OCCT root folder ($CASROOT).
72b7576f 257
504a8968 258Additional test folders can be added to the test system by defining environment variable *CSF_TestScriptsPath*. This should be list of paths separated by semicolons (*;*) on Windows
6d368502 259or colons (*:*) on Linux or Mac. Upon DRAW launch, path to *tests* subfolder of OCCT is added at the end of this variable automatically.
504a8968 260
261Each test folder is expected to contain:
6d368502 262 * Optional file *parse.rules* defining patterns for interpretation of test results, common for all groups in this folder
72b7576f 263 * One or several test group directories.
264
265Each group directory contains:
266
504a8968 267 * File *grids.list* that identifies this test group and defines list of test grids in it.
268 * Test grids (sub-directories), each containing set of scripts for test cases, and optional files *cases.list*, *parse.rules*, *begin* and *end*.
72b7576f 269 * Optional sub-directory data
72b7576f 270
504a8968 271By convention, names of test groups, grids, and cases should contain no spaces and be lower-case.
272The names *begin, end, data, parse.rules, grids.list* and *cases.list* are reserved.
72b7576f 273
504a8968 274General layout of test scripts is shown in Figure 1.

280
281@subsubsection testmanual_2_2_1 Group Names
282
504a8968 283The names of directories of test groups containing systematic test grids correspond to the functionality tested by each group.
284
72b7576f 285Example:
286
504a8968 287~~~~~
72b7576f 288 caf
289 mesh
290 offset
504a8968 291~~~~~
72b7576f 292
504a8968 293Test group *bugs* is used to collect the tests coming from bug reports. Group *demo* collects tests of the test system, DRAW, samples, etc.
72b7576f 294
504a8968 295@subsubsection testmanual_2_2_2 File "grids.list"
296
297This test group contains file *grids.list*, which defines an ordered list of grids in this group in the following format:
72b7576f 298
299~~~~~~~~~~~~~~~~~
300001 gridname1
301002 gridname2
302...
303NNN gridnameN

312
504a8968 313@subsubsection testmanual_2_2_3 File "begin"
72b7576f 314
504a8968 315This file is a Tcl script. It is executed before every test in the current group.
72b7576f 316Usually it loads necessary Draw commands, sets common parameters and defines
317additional Tcl functions used in test scripts.
504a8968 318
72b7576f 319Example:
320
321~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
322 pload TOPTEST ;# load topological command
323 set cpulimit 300 ;# set maximum time allowed for script execution
324~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
325
504a8968 326@subsubsection testmanual_2_2_4 File "end"
72b7576f 327
504a8968 328This file is a TCL script. It is executed after every test in the current group. Usually it checks the results of script work, makes a snap-shot of the viewer and writes *TEST COMPLETED* to the output.
72b7576f 329
504a8968 330Note: *TEST COMPLETED* string should be present in the output to indicate that the test is finished without crash.
331
67d7f07f 332See @ref testmanual_3 "Creation and modification of tests" chapter for more information.
504a8968 333
334Example:
335~~~~~
72b7576f 336 if { [isdraw result] } {
337 checkshape result
338 } else {
4ee1bdf4 339 puts "Error: The result shape can not be built"
72b7576f 340 }
4ee1bdf4 341 puts "TEST COMPLETED"
504a8968 342~~~~~
343
344@subsubsection testmanual_2_2_5 File "parse.rules"
345
346The test group may contain *parse.rules* file. This file defines patterns used for analysis of the test execution log and deciding the status of the test run.
347
348Each line in the file should specify a status (single word), followed by a regular expression delimited by slashes (*/*) that will be matched against lines in the test output log to check if it corresponds to this status.
349
251a7984 350The regular expressions should follow <a href="http://www.tcl.tk/man/tcl/TclCmd/re_syntax.htm">Tcl syntax</a>, with a special exception that "\b" is considered as word limit (Perl-style), in addition to "\y" used in Tcl.
504a8968 351
352The rest of the line can contain a comment message, which will be added to the test report when this status is detected.
72b7576f 353
72b7576f 354Example:
355
504a8968 356~~~~~
6d368502 357 FAILED /\b[Ee]xception\b/ exception
358 FAILED /\bError\b/ error
72b7576f 359 SKIPPED /Cannot open file for reading/ data file is missing
360 SKIPPED /Could not read file .*, abandon/ data file is missing
504a8968 361~~~~~
72b7576f 362
363Lines starting with a *#* character and blank lines are ignored to allow comments and spacing.
72b7576f 364
dcc0a33e 365See @ref testmanual_details_results "Interpretation of test results" chapter for details.
504a8968 366
367If a line matches several rules, the first one applies. Rules defined in the grid are checked first, then rules in the group, then rules in the test root directory. This allows defining some rules on the grid level with status *IGNORE* to ignore messages that would otherwise be treated as errors due to the group level rules.
368
72b7576f 369Example:
370
371~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
e5bd0d98 372 FAILED /\\bFaulty\\b/ bad shape
72b7576f 373 IGNORE /^Error [23]d = [\d.-]+/ debug output of blend command
374 IGNORE /^Tcl Exception: tolerance ang : [\d.-]+/ blend failure
375~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
376
504a8968 377@subsubsection testmanual_2_2_6 Directory "data"
67d7f07f 378The test group may contain subdirectory *data*, where test scripts shared by different test grids can be put. See also @ref testmanual_2_3_5 "Directory data".

381
382@subsubsection testmanual_2_3_1 Grid Names
383
504a8968 384The folder of a test group can have several sub-directories (Grid 1… Grid N) defining test grids.
385Each directory contains a set of related test cases. The name of a directory should correspond to its contents.

504a8968 396Here *caf* is the name of the test group and *basic*, *bugs*, *presentation*, etc. are the names of grids.
72b7576f 397
504a8968 398@subsubsection testmanual_2_3_2 File "begin"
399
400This file is a TCL script executed before every test in the current grid.
72b7576f 401
72b7576f 402Usually it sets variables specific for the current grid.
504a8968 403
72b7576f 404Example:
405
406~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
407 set command bopfuse ;# command tested in this grid
408~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
409
504a8968 410@subsubsection testmanual_2_3_3 File "end"
411
412This file is a TCL script executed after every test in current grid.
413
414Usually it executes a specific sequence of commands common for all tests in the grid.
72b7576f 415
72b7576f 416Example:
417
418~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
936f43da 419 vdump $imagedir/${casename}.png ;# makes a snap-shot of AIS viewer
72b7576f 420~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
421
504a8968 422@subsubsection testmanual_2_3_4 File "cases.list"
72b7576f 423
424The grid directory can contain an optional file cases.list
504a8968 425defining an alternative location of the test cases.
426This file should contain a single line defining the relative path to the collection of test cases.
72b7576f 427
428Example:
429
504a8968 430~~~~~
72b7576f 431../data/simple
504a8968 432~~~~~
433
434This option is used for creation of several grids of tests with the same data files and operations but performed with differing parameters. The common scripts are usually located place in the common
435subdirectory of the test group, <i>data/simple</i> for example.
72b7576f 436
504a8968 437If file *cases.list* exists, the grid directory should not contain any test cases.
72b7576f 438The specific parameters and pre- and post-processing commands
504a8968 439for test execution in this grid should be defined in the files *begin* and *end*.
440
441
442@subsubsection testmanual_2_3_5 Directory "data"
443
444The test grid may contain subdirectory *data*, containing data files used in tests (BREP, IGES, STEP, etc.) of this grid.
72b7576f 445
446@subsection testmanual_2_4 Test Cases
447
504a8968 448The test case is a TCL script, which performs some operations using DRAW commands
449and produces meaningful messages that can be used to check the validity of the result.
450
72b7576f 451Example:
452
453~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
454 pcylinder c1 10 20 ;# create first cylinder
455 pcylinder c2 5 20 ;# create second cylinder
456 ttranslate c2 5 0 10 ;# translate second cylinder to x,y,z
457 bsection result c1 c2 ;# create a section of two cylinders
458 checksection result ;# will output error message if result is bad
459~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
460
504a8968 461The test case can have any name (except for the reserved names *begin, end, data, cases.list* and *parse.rules*).
72b7576f 462For systematic grids it is usually a capital English letter followed by a number.
463
464Example:
465
504a8968 466~~~~~
72b7576f 467 A1
468 A2
469 B1
470 B2
504a8968 471~~~~~
72b7576f 472
504a8968 473Such naming facilitates compact representation of tests execution results in tabular format within HTML reports.

476@section testmanual_3 Creation And Modification Of Tests
477
478This section describes how to add new tests and update existing ones.
479
480@subsection testmanual_3_1 Choosing Group, Grid, and Test Case Name
481
504a8968 482The new tests are usually added in the frame of processing issues in OCCT Mantis tracker.
72b7576f 483Such tests in general should be added to group bugs, in the grid
67d7f07f 484corresponding to the affected OCCT functionality. See @ref testmanual_5_2 "Mapping of OCCT functionality to grid names in group bugs".
504a8968 485
486New grids can be added as necessary to contain tests for the functionality not yet covered by existing test grids.
487The test case name in the bugs group should be prefixed by the ID of the corresponding issue in Mantis (without leading zeroes) with prefix *bug*. It is recommended to add a suffix providing a hint on the tested situation. If more than one test is added for a bug, they should be distinguished by suffixes; either meaningful or just ordinal numbers.
72b7576f 488
489Example:
490
491~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
504a8968 492 bug12345_coaxial
493 bug12345_orthogonal_1
494 bug12345_orthogonal_2
72b7576f 495~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
496
504a8968 497If the new test corresponds to a functionality already covered by the existing systematic test grid (e.g. group *mesh* for *BRepMesh* issues), this test can be added (or moved later by OCC team) to that grid.
72b7576f 498
499@subsection testmanual_3_2 Adding Data Files Required for a Test
500
ae3eaf7b 501It is advisable to make self-contained test scripts whenever possible, so as they could be used in the environments where data files are not available. For that simple geometric objects and shapes can be created using DRAW commands in the test script itself.
504a8968 502
ae3eaf7b 503If the test requires a data file, it should be put to the directory listed in environment variable *CSF_TestDataPath*.
936f43da 504Alternatively, it can be put to subdirectory *data* of the test grid.
505It is recommended to prefix the data file with the corresponding issue id prefixed by *bug*, e.g. *bug12345_face1.brep*, to avoid possible conflicts with names of existing data files.
504a8968 506
ae3eaf7b 507Note that when the test is integrated to the master branch, OCC team will move the data file to the data files repository, to keep OCCT sources repository clean from data files.
504a8968 508
ae3eaf7b 509When you prepare a test script, try to minimize the size of involved data model. For instance, if the problem detected on a big shape can be reproduced on a single face extracted from that shape, use only that face in the test.
504a8968 510
511
512@subsection testmanual_3_3 Adding new DRAW commands
513
514If the test cannot be implemented using available DRAW commands, consider the following possibilities:
515* If the existing DRAW command can be extended to enable possibility required for a test in a natural way (e.g. by adding an option to activate a specific mode of the algorithm), this way is recommended. This change should be appropriately documented in a relevant Mantis issue.
516* If the new command is needed to access OCCT functionality not exposed to DRAW previously, and this command can be potentially reused (for other tests), it should be added to the package where similar commands are implemented (use *getsource* DRAW command to get the package name). The name and arguments of the new command should be chosen to keep similarity with the existing commands. This change should be documented in a relevant Mantis issue.
517* Otherwise the new command implementing the actions needed for this particular test should be added in *QABugs* package. The command name should be formed by the Mantis issue ID prefixed by *bug*, e.g. *bug12345*.
518
519Note that a DRAW command is expected to return 0 in case of a normal completion, and 1 (Tcl exception) if it is incorrectly used (e.g. a wrong number of input arguments). Thus if the new command needs to report a test error, this should be done by outputting an appropriate error message rather than by returning a non-zero value.
ae3eaf7b 520File names must be encoded in the script rather than in the DRAW command and passed to the DRAW command as an argument.
504a8968 521
522@subsection testmanual_3_4 Script Implementation
523
524The test should run commands necessary to perform the tested operations, in general assuming a clean DRAW session. The required DRAW modules should be loaded by *pload* command, if it is not done by *begin* script. The messages produced by commands in a standard output should include identifiable messages on the discovered problems if any.
525
526Usually the script represents a set of commands that a person would run interactively to perform the operation and see its results, with additional comments to explain what happens.
527
72b7576f 528Example:
504a8968 529~~~~~
530# Simple test of fusing box and sphere
531box b 10 10 10
532sphere s 5
533bfuse result b s
534checkshape result
535~~~~~
72b7576f 536
504a8968 537Make sure that file *parse.rules* in the grid or group directory contains a regular expression to catch possible messages indicating the failure of the test.
538
539For instance, for catching errors reported by *checkshape* command relevant grids define a rule to recognize its report by the word *Faulty*:
540
541~~~~~
542FAILED /\bFaulty\b/ bad shape
543~~~~~
544
545For the messages generated in the script it is recommended to use the word 'Error' in the error message.
72b7576f 546
72b7576f 547Example:
548
504a8968 549~~~~~
550set expected_length 11
551if { [expr $actual_length - $expected_length] > 0.001 } {
552 puts "Error: The length of the edge should be $expected_length"
553}
554~~~~~
555
556At the end, the test script should output *TEST COMPLETED* string to mark a successful completion of the script. This is often done by the *end* script in the grid.
557
558When the test script requires a data file, use Tcl procedure *locate_data_file* to get a path to it, instead of putting the path explicitly. This will allow easy move of the data file from OCCT sources repository to the data files repository without the need to update the test script.
72b7576f 559
72b7576f 560Example:
561
504a8968 562~~~~~
563stepread [locate_data_file CAROSKI_COUPELLE.step] a *
564~~~~~
565
936f43da 566When the test needs to produce some snapshots or other artefacts, use Tcl variable *imagedir* as the location where such files should be put.
ae3eaf7b 567* Command *testgrid* sets this variable to the subdirectory of the results folder corresponding to the grid.
568* Command *test* by default creates a dedicated temporary directory in the system temporary folder (normally the one specified by environment variable *TempDir*, *TEMP*, or *TMP*) for each execution, and sets *imagedir* to that location.
569
570However if variable *imagedir* is defined on the top level of Tcl interpretor, command *test* will use it instead of creating a new directory.
936f43da 571
572Use Tcl variable *casename* to prefix all files produced by the test.
573This variable is set to the name of the test case.
ae3eaf7b 574
575The test system can recognize an image file (snapshot) and include it in HTML log and differences if its name starts with the name of the test case (use variable *casename*), optionally followed by underscore or dash and arbitrary suffix.
576
936f43da 577The image format (defined by extension) should be *png*.
72b7576f 578
72b7576f 579Example:
504a8968 580~~~~~
936f43da 581xwd $imagedir/${casename}.png
504a8968 582vdisplay result; vfit
936f43da 583vdump $imagedir/${casename}-axo.png
504a8968 584vfront; vfit
936f43da 585vdump $imagedir/${casename}-front.png
504a8968 586~~~~~
72b7576f 587
504a8968 588would produce:
589~~~~~
590A1.png
591A1-axo.png
592A1-front.png
593~~~~~
72b7576f 594
504a8968 595Note that OCCT must be built with FreeImage support to be able to produce usable images.
72b7576f 596
936f43da 597Other Tcl variables defined during the test execution are:
ae3eaf7b 598- *groupname*: name of the test group;
599- *gridname*: name of the test grid;
600- *dirname*: path to the root directory of the current set of test scripts.
936f43da 601
504a8968 602In order to ensure that the test works as expected in different environments, observe the following additional rules:
603* Avoid using external commands such as *grep, rm,* etc., as these commands can be absent on another system (e.g. on Windows); use facilities provided by Tcl instead.
3f812249 604* Do not put call to *locate_data_file* in catch statement -- this can prevent correct interpretation of the missing data file by the test system.
6d368502 605* Do not use commands *decho* and *dlog* in the test script, to avoid interference with use of these commands by the test system.
72b7576f 606
dcc0a33e 607@subsection testmanual_details_results Interpretation of test results
72b7576f 608
504a8968 609The result of the test is evaluated by checking its output against patterns defined in the files *parse.rules* of the grid and group.
72b7576f 610
504a8968 611The OCCT test system recognizes five statuses of the test execution:
612* SKIPPED: reported if a line matching SKIPPED pattern is found (prior to any FAILED pattern). This indicates that the test cannot be run in the current environment; the most typical case is the absence of the required data file.
6d368502 613* FAILED: reported if a line matching pattern with status FAILED is found (unless it is masked by the preceding IGNORE pattern or a TODO or REQUIRED statement), or if message TEST COMPLETED or at least one of REQUIRED patterns is not found. This indicates that the test has produced a bad or unexpected result, and usually means a regression.
614* BAD: reported if the test script output contains one or several TODO statements and the corresponding number of matching lines in the log. This indicates a known problem. The lines matching TODO statements are not checked against other patterns and thus will not cause a FAILED status.
504a8968 615* IMPROVEMENT: reported if the test script output contains a TODO statement for which no corresponding line is found. This is a possible indication of improvement (a known problem has disappeared).
616* OK: reported if none of the above statuses have been assigned. This means that the test has passed without problems.
72b7576f 617
504a8968 618Other statuses can be specified in *parse.rules* files, these will be classified as FAILED.
72b7576f 619
504a8968 620For integration of the change to OCCT repository, all tests should return either OK or BAD status.
621The new test created for an unsolved problem should return BAD. The new test created for a fixed problem should return FAILED without the fix, and OK with the fix.
72b7576f 622
504a8968 623@subsection testmanual_3_6 Marking BAD cases
72b7576f 624
ae3eaf7b 625If the test produces an invalid result at a certain moment then the corresponding bug should be created in the OCCT issue tracker located at http://tracker.dev.opencascade.org, and the problem should be marked as TODO in the test script.
72b7576f 626
504a8968 627The following statement should be added to such a test script:
628~~~~~
629puts "TODO BugNumber ListOfPlatforms: RegularExpression"
630~~~~~
631
632Here:
633* *BugNumber* is the bug ID in the tracker. For example: #12345.
863f782a 634* *ListOfPlatforms* is a list of platforms, at which the bug is reproduced (Linux, Windows, MacOS, or All). Note that the platform name is custom for the OCCT test system; Use procedure *checkplatform* to get the platform name.
72b7576f 635
636Example:
504a8968 637~~~~~
863f782a 638Draw[2]> checkplatform
639Windows
504a8968 640~~~~~
72b7576f 641
ae3eaf7b 642* RegularExpression is a regular expression, which should be matched against the line indicating the problem in the script output.
72b7576f 643
72b7576f 644Example:
504a8968 645~~~~~
646puts "TODO #22622 Mandriva2008: Abort .* an exception was raised"
647~~~~~
72b7576f 648
504a8968 649The parser checks the test output and if an output line matches the *RegularExpression* then it will be assigned a BAD status instead of FAILED.
72b7576f 650
504a8968 651A separate TODO line must be added for each output line matching an error expression to mark the test as BAD. If not all TODO messages are found in the test log, the test will be considered as possible improvement.
652
653To mark the test as BAD for an incomplete case (when the final *TEST COMPLETE* message is missing) the expression *TEST INCOMPLETE* should be used instead of the regular expression.
72b7576f 654
655Example:
656
504a8968 657~~~~~
658puts "TODO OCC22817 All: exception.+There are no suitable edges"
659puts "TODO OCC22817 All: \\*\\* Exception \\*\\*"
660puts "TODO OCC22817 All: TEST INCOMPLETE"
661~~~~~
72b7576f 662
6d368502 663@subsection testmanual_3_7 Marking required output
664
251a7984 665To check the obtained test output matches the expected results considered correct, add REQUIRED statement for each specific message.
666For that, the following statement should be added to the corresponding test script:
6d368502 667
668~~~~~
669puts "REQUIRED ListOfPlatforms: RegularExpression"
670~~~~~
671
672Here *ListOfPlatforms* and *RegularExpression* have the same meaning as in TODO statements described above.
673
251a7984 674The REQUIRED statement can also be used to mask the message that would normally be interpreted as error (according to the rules defined in *parse.rules*) but should not be considered as such within the current test.
6d368502 675
676Example:
677~~~~~
b502ddc1 678puts "REQUIRED Linux: Faulty shapes in variables faulty_1 to faulty_5"
6d368502 679~~~~~
680
681This statement notifies test system that errors reported by *checkshape* command are expected in that test case, and test should be considered as OK if this message appears, despite of presence of general rule stating that 'Faulty' signals failure.
504a8968 682
6d368502 683If output does not contain required statement, test case will be marked as FAILED.
504a8968 684

72b7576f 686
687@subsection testmanual_4_1 Running Tests on Older Versions of OCCT
688
ae3eaf7b 689Sometimes it might be necessary to run tests on the previous versions of OCCT (<= 6.5.4) that do not include this test system. This can be done by adding DRAW configuration file *DrawAppliInit* in the directory, which is current by the moment of DRAW start-up, to load test commands and to define the necessary environment.
72b7576f 690
504a8968 691Note: in OCCT 6.5.3, file *DrawAppliInit* already exists in <i>$CASROOT/src/DrawResources</i>, new commands should be added to this file instead of a new one in the current directory.
692
693For example, let us assume that *d:/occt* contains an up-to-date version of OCCT sources with tests, and the test data archive is unpacked to *d:/test-data*):
694
695~~~~~
696set env(CASROOT) d:/occt
697set env(CSF_TestScriptsPath) $env(CASROOT)/tests
698source $env(CASROOT)/src/DrawResources/TestCommands.tcl
699set env(CSF_TestDataPath) $env(CASROOT)/data;d:/test-data
700return
701~~~~~
702
ae3eaf7b 703Note that on older versions of OCCT the tests are run in compatibility mode and thus not all output of the test command can be captured; this can lead to absence of some error messages (can be reported as either a failure or an improvement).
504a8968 704
705@subsection testmanual_4_2 Adding custom tests
706
707You can extend the test system by adding your own tests. For that it is necessary to add paths to the directory where these tests are located, and one or more additional data directories, to the environment variables *CSF_TestScriptsPath* and *CSF_TestDataPath*. The recommended way for doing this is using DRAW configuration file *DrawAppliInit* located in the directory which is current by the moment of DRAW start-up.
708
4ee1bdf4 709Use Tcl command <i>_path_separator</i> to insert a platform-dependent separator to the path list.
504a8968 710
711For example:
712~~~~~
713set env(CSF_TestScriptsPath) \
714 $env(TestScriptsPath)[_path_separator]d:/MyOCCTProject/tests
715set env(CSF_TestDataPath) \
716 d:/occt/test-data[_path_separator]d:/MyOCCTProject/data
717return ;# this is to avoid an echo of the last command above in cout
718~~~~~
719
720@subsection testmanual_4_3 Parallel execution of tests
721
722For better efficiency, on computers with multiple CPUs the tests can be run in parallel mode. This is default behavior for command *testgrid* : the tests are executed in parallel processes (their number is equal to the number of CPUs available on the system). In order to change this behavior, use option parallel followed by the number of processes to be used (1 or 0 to run sequentially).
72b7576f 723
87f42a3f 724Note that the parallel execution is only possible if Tcl extension package *Thread* is installed.
725If this package is not available, *testgrid* command will output a warning message.
72b7576f 726
504a8968 727@subsection testmanual_4_4 Checking non-regression of performance, memory, and visualization
72b7576f 728
504a8968 729Some test results are very dependent on the characteristics of the workstation, where they are performed, and thus cannot be checked by comparison with some predefined values. These results can be checked for non-regression (after a change in OCCT code) by comparing them with the results produced by the version without this change. The most typical case is comparing the result obtained in a branch created for integration of a fix (CR***) with the results obtained on the master branch before that change is made.
730
731OCCT test system provides a dedicated command *testdiff* for comparing CPU time of execution, memory usage, and images produced by the tests.
732
733~~~~~
734testdiff dir1 dir2 [groupname [gridname]] [options...]
735~~~~~
736Here *dir1* and *dir2* are directories containing logs of two test runs.
737
738Possible options are:
3f812249 739* <i>-save \<filename\> </i> -- saves the resulting log in a specified file (<i>$dir1/diff-$dir2.log</i> by default). HTML log is saved with the same name and extension .html;
740* <i>-status {same|ok|all}</i> -- allows filtering compared cases by their status:
741 * *same* -- only cases with same status are compared (default);
742 * *ok* -- only cases with OK status in both logs are compared;
743 * *all* -- results are compared regardless of status;
744* <i>-verbose \<level\> </i> -- defines the scope of output data:
745 * 1 -- outputs only differences;
746 * 2 -- additionally outputs the list of logs and directories present in one of directories only;
747 * 3 -- (by default) additionally outputs progress messages;
44fae8b1 748* <i>-image [filename]</i> - compare images and save the resulting log in specified file (<i>$dir1/diffimage-$dir2.log</i> by default)
749* <i>-cpu [filename]</i> - compare overall CPU and save the resulting log in specified file (<i>$dir1/diffcpu-$dir2.log</i> by default)
750* <i>-memory [filename]</i> - compare memory delta and save the resulting log in specified file (<i>$dir1/diffmemory-$dir2.log</i> by default)
751* <i>-highlight_percent \<value\></i> - highlight considerable (>value in %) deviations of CPU and memory (default value is 5%)
72b7576f 752
72b7576f 753Example:

757~~~~~
758
759Particular tests can generate additional data that need to be compared by *testdiff* command.
760For that, for each parameter to be controlled, the test should produce the line containing keyword "COUNTER* followed by arbitrary name of the parameter, then colon and numeric value of the parameter.
761
762Example of test code:
763

5ae01c85 1072@subsection testmanual_5_3 Recommended approaches to checking test results
504a8968 1073
1074@subsubsection testmanual_5_3_1 Shape validity
1075
1076Run command *checkshape* on the result (or intermediate) shape and make sure that *parse.rules* of the test grid or group reports bad shapes (usually recognized by word "Faulty") as error.
1077
1078Example
1079~~~~~
1080checkshape result
1081~~~~~
1082
5ae01c85 1083To check the number of faults in the shape command *checkfaults* can be used.
1084
1085Use: checkfaults shape source_shape [ref_value=0]
1086
1087The default syntax of *checkfaults* command:
1088~~~~~
1089checkfaults results a_1
1090~~~~~
1091
1092The command will check the number of faults in the source shape (*a_1*) and compare it
1093with number of faults in the resulting shape (*result*). If shape *result* contains
1094more faults, you will get an error:
1095~~~~~
1096checkfaults results a_1
1097Error : Number of faults is 5
1098~~~~~
1099It is possible to set the reference value for comparison (reference value is 4):
1100
1101~~~~~
1102checkfaults results a_1 4
1103~~~~~
1104
1105If number of faults in the resulting shape is unstable, reference value should be set to "-1".
1106As a result command *checkfaults* will return the following error:
1107
1108~~~~~
1109checkfaults results a_1 -1
1110Error : Number of faults is UNSTABLE
1111~~~~~
1112
504a8968 1113@subsubsection testmanual_5_3_2 Shape tolerance
dcb359e0 1114
504a8968 1115The maximal tolerance of sub-shapes of each kind of the resulting shape can be extracted from output of tolerance command as follows:
1116
1117~~~~~
1118set tolerance [tolerance result]
1119regexp { *FACE +: +MAX=([-0-9.+eE]+)} $tolerance dummy max_face
1120regexp { *EDGE +: +MAX=([-0-9.+eE]+)} $tolerance dummy max_edgee
1121regexp { *VERTEX +: +MAX=([-0-9.+eE]+)} $tolerance dummy max_vertex
1122~~~~~
1123
5ae01c85 1124It is possible to use command *checkmaxtol* to check maximal tolerance of shape and compare it with reference value.
1125
fb60057d 1126Use: checkmaxtol shape [options...]
5ae01c85 1127
1128Allowed options are:
dcb359e0 1129 * <i>-ref</i> -- reference value of maximum tolerance;
1130 * <i>-source</i> -- list of shapes to compare with;
1131 * <i>-min_tol</i> -- minimum tolerance for comparison;
1132 * <i>-multi_tol</i> -- tolerance multiplier.
5ae01c85 1133
5ae01c85 1134The default syntax of *checkmaxtol* command for comparison with the reference value:
1135~~~~~
fb60057d 1136checkmaxtol result -ref 0.00001
5ae01c85 1137~~~~~
1138
1139There is an opportunity to compare max tolerance of resulting shape with max tolerance of source shape.
1140In the following example command *checkmaxtol* gets max tolerance among objects *a_1* and *a_2*.
1141Then it chooses the maximum value between founded tolerance and value -min_tol (0.000001)
1142and multiply it on the coefficient -multi_tol (i.e. 2):
1143
1144~~~~~
fb60057d 1145checkmaxtol result -source {a_1 a_2} -min_tol 0.000001 -multi_tol 2
5ae01c85 1146~~~~~
1147
1148If the value of maximum tolerance more than founded tolerance for comparison, the command will return an error.
1149
fb60057d 1150Also, command *checkmaxtol* can be used to get max tolerance of the shape:
1151
1152~~~~~
1153set maxtol [checkmaxtol result]
1154~~~~~
1155
504a8968 1156@subsubsection testmanual_5_3_3 Shape volume, area, or length
1157
1158Use command *vprops, sprops,* or *lprops* to correspondingly measure volume, area, or length of the shape produced by the test. The value can be extracted from the result of the command by *regexp*.
1159
1160Example:
1161~~~~~
1162# check area of shape result with 1% tolerance
1163regexp {Mass +: +([-0-9.+eE]+)} [sprops result] dummy area
1164if { abs($area - $expected) > 0.1 + 0.01 * abs ($area) } {
1165 puts "Error: The area of result shape is $area, while expected $expected"
1166}
1167~~~~~
1168
1169@subsubsection testmanual_5_3_4 Memory leaks
1170
dcb359e0 1171The test system measures the amount of memory used by each test case. Considerable deviations (as well as the overall difference) in comparison with reference results can be reported by command *testdiff* (see @ref testmanual_4_4).
504a8968 1172
dcb359e0 1173To check memory leak on a particular operation, run it in a cycle, measure the memory consumption at each step and compare it with a threshold value.
1174The command *checktrend* (defined in *tests/bugs/begin*) can be used to analyze a sequence of memory measurements and to get a statistically based evaluation of the leak presence.
504a8968 1175
1176Example:
1177~~~~~
1178set listmem {}
1179for {set i 1} {$i < 100} {incr i} {
1180 # run suspect operation
1181
1182 # check memory usage (with tolerance equal to half page size)
1183 lappend listmem [expr [meminfo w] / 1024]
1184 if { [checktrend $listmem 0 256 "Memory leak detected"] } {
1185 puts "No memory leak, $i iterations"
1186 break
1187 }
1188}
1189~~~~~
1190
1191@subsubsection testmanual_5_3_5 Visualization
1192
dcb359e0 1193The following command sequence allows you to take a snapshot of the viewer, give it the name of the test case, and save in the directory indicated by Tcl variable *imagedir*.
504a8968 1194
1195~~~~~
1196vinit
1197vclear
1198vdisplay result
1199vsetdispmode 1
1200vfit
1201vzfit
1202vdump $imagedir/${casename}_shading.png
1203~~~~~
1204
1205This image will be included in the HTML log produced by *testgrid* command and will be checked for non-regression through comparison of images by command *testdiff*.
5ae01c85 1206
5747059b 1207Also it is possible to use command *checkview* to make a snapshot of the viewer.
1208
1209Use: checkview [options...]
1210Allowed options are:
dcb359e0 1211* <i>-display shapename </i> -- displays shape with name *shapename*;
1212* <i>-3d </i> -- displays shape in 3d viewer;
1213* <i>-2d [ v2d / smallview ] </i> - displays shape in 2d viewer (the default viewer is *smallview*);
1214* <i>-path PATH</i> -- sets the location of the saved viewer screenshot;
1215* <i>-vdispmode N</i> -- sets *vdispmode* for 3d viewer (default value is 1)
1216* <i>-screenshot</i> -- makes a screenshot of already created viewer
1217* The procedure can check a property of shape (length, area or volume) and compare it with value *N*:
1218 * <i>-l [N]</i>
1219 * <i>-s [N]</i>
