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.
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).
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
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.
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
46@subsubsection testmanual_1_3_1 Setup
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.
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
504a8968 65To run all tests, type command *testgrid*
72b7576f 66
504a8968 69~~~~~
70Draw[]> testgrid
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
504a8968 87Example:
72b7576f 89~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.tcl}
90 Tests summary
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
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:
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
118Draw[]> testgrid -regress d:/occt/last_results
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
87f42a3f 142To run a single test, type command *test* followed by names of group, grid, and test case.
72b7576f 143
147 Draw[1]> test blend simple A1
148 CASE blend simple A1: OK
149 Draw[2]>
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>.
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.
ae3eaf7b 157Type <i>help test</i> in DRAW prompt to get help on options supported by *test* command:
936f43da 158
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.
1954. If the test uses data file(s) that are not yet present in the test database, it is possible to put them to (sub)directory pointed out by *CSF_TestDataPath* variable for running test. The files should be attached to the Mantis issue corresponding to the tested modification.
1965. 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.

221@section testmanual_2 Organization of Test Scripts
223@subsection testmanual_2_1 General Layout
225Standard OCCT tests are located in subdirectory tests of the OCCT root folder ($CASROOT).
72b7576f 226
504a8968 227Additional 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 228or colons (*:*) on Linux or Mac. Upon DRAW launch, path to *tests* subfolder of OCCT is added at the end of this variable automatically.
504a8968 229
230Each test folder is expected to contain:
6d368502 231 * Optional file *parse.rules* defining patterns for interpretation of test results, common for all groups in this folder
72b7576f 232 * One or several test group directories.
234Each group directory contains:
504a8968 236 * File *grids.list* that identifies this test group and defines list of test grids in it.
237 * Test grids (sub-directories), each containing set of scripts for test cases, and optional files *cases.list*, *parse.rules*, *begin* and *end*.
72b7576f 238 * Optional sub-directory data
72b7576f 239
504a8968 240By convention, names of test groups, grids, and cases should contain no spaces and be lower-case.
241The names *begin, end, data, parse.rules, grids.list* and *cases.list* are reserved.
72b7576f 242
504a8968 243General layout of test scripts is shown in Figure 1.

72b7576f 248
249@subsection testmanual_2_2 Test Groups
251@subsubsection testmanual_2_2_1 Group Names
504a8968 253The names of directories of test groups containing systematic test grids correspond to the functionality tested by each group.
72b7576f 255Example:
504a8968 257~~~~~
72b7576f 258 caf
259 mesh
260 offset
504a8968 261~~~~~
72b7576f 262
504a8968 263Test group *bugs* is used to collect the tests coming from bug reports. Group *demo* collects tests of the test system, DRAW, samples, etc.
72b7576f 264
504a8968 265@subsubsection testmanual_2_2_2 File "grids.list"
267This test group contains file *grids.list*, which defines an ordered list of grids in this group in the following format:
72b7576f 268
270001 gridname1
271002 gridname2
273NNN gridnameN
279 001 basic
280 002 advanced
504a8968 283@subsubsection testmanual_2_2_3 File "begin"
72b7576f 284
504a8968 285This file is a Tcl script. It is executed before every test in the current group.
72b7576f 286Usually it loads necessary Draw commands, sets common parameters and defines
287additional Tcl functions used in test scripts.
504a8968 288
72b7576f 289Example:
292 pload TOPTEST ;# load topological command
293 set cpulimit 300 ;# set maximum time allowed for script execution
504a8968 296@subsubsection testmanual_2_2_4 File "end"
72b7576f 297
504a8968 298This 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 299
504a8968 300Note: *TEST COMPLETED* string should be present in the output to indicate that the test is finished without crash.
67d7f07f 302See @ref testmanual_3 "Creation and modification of tests" chapter for more information.
504a8968 303
72b7576f 306 if { [isdraw result] } {
307 checkshape result
308 } else {
4ee1bdf4 309 puts "Error: The result shape can not be built"
72b7576f 310 }
4ee1bdf4 311 puts "TEST COMPLETED"
504a8968 312~~~~~
314@subsubsection testmanual_2_2_5 File "parse.rules"
316The 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.
318Each 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.
251a7984 320The 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 321
322The rest of the line can contain a comment message, which will be added to the test report when this status is detected.
72b7576f 323
72b7576f 324Example:
504a8968 326~~~~~
6d368502 327 FAILED /\b[Ee]xception\b/ exception
328 FAILED /\bError\b/ error
72b7576f 329 SKIPPED /Cannot open file for reading/ data file is missing
330 SKIPPED /Could not read file .*, abandon/ data file is missing
504a8968 331~~~~~
72b7576f 332
333Lines starting with a *#* character and blank lines are ignored to allow comments and spacing.
72b7576f 334
dcc0a33e 335See @ref testmanual_details_results "Interpretation of test results" chapter for details.
504a8968 336
337If 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.
72b7576f 339Example:
e5bd0d98 342 FAILED /\\bFaulty\\b/ bad shape
72b7576f 343 IGNORE /^Error [23]d = [\d.-]+/ debug output of blend command
344 IGNORE /^Tcl Exception: tolerance ang : [\d.-]+/ blend failure
504a8968 347@subsubsection testmanual_2_2_6 Directory "data"
67d7f07f 348The 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".
504a8968 349
72b7576f 350@subsection testmanual_2_3 Test Grids
352@subsubsection testmanual_2_3_1 Grid Names
504a8968 354The folder of a test group can have several sub-directories (Grid 1… Grid N) defining test grids.
355Each directory contains a set of related test cases. The name of a directory should correspond to its contents.
72b7576f 356
504a8968 359~~~~~
72b7576f 360caf
361 basic
362 bugs
363 presentation
504a8968 364~~~~~
72b7576f 365
504a8968 366Here *caf* is the name of the test group and *basic*, *bugs*, *presentation*, etc. are the names of grids.
72b7576f 367
504a8968 368@subsubsection testmanual_2_3_2 File "begin"
370This file is a TCL script executed before every test in the current grid.
72b7576f 371
72b7576f 372Usually it sets variables specific for the current grid.
504a8968 373
72b7576f 374Example:
377 set command bopfuse ;# command tested in this grid
504a8968 380@subsubsection testmanual_2_3_3 File "end"
382This file is a TCL script executed after every test in current grid.
384Usually it executes a specific sequence of commands common for all tests in the grid.
72b7576f 385
72b7576f 386Example:
936f43da 389 vdump $imagedir/${casename}.png ;# makes a snap-shot of AIS viewer
72b7576f 390~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
504a8968 392@subsubsection testmanual_2_3_4 File "cases.list"
72b7576f 393
394The grid directory can contain an optional file cases.list
504a8968 395defining an alternative location of the test cases.
396This file should contain a single line defining the relative path to the collection of test cases.
72b7576f 397
504a8968 400~~~~~
72b7576f 401../data/simple
504a8968 402~~~~~
404This 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
405subdirectory of the test group, <i>data/simple</i> for example.
72b7576f 406
504a8968 407If file *cases.list* exists, the grid directory should not contain any test cases.
72b7576f 408The specific parameters and pre- and post-processing commands
504a8968 409for test execution in this grid should be defined in the files *begin* and *end*.
412@subsubsection testmanual_2_3_5 Directory "data"
414The test grid may contain subdirectory *data*, containing data files used in tests (BREP, IGES, STEP, etc.) of this grid.
72b7576f 415
416@subsection testmanual_2_4 Test Cases
504a8968 418The test case is a TCL script, which performs some operations using DRAW commands
419and produces meaningful messages that can be used to check the validity of the result.
72b7576f 421Example:
424 pcylinder c1 10 20 ;# create first cylinder
425 pcylinder c2 5 20 ;# create second cylinder
426 ttranslate c2 5 0 10 ;# translate second cylinder to x,y,z
427 bsection result c1 c2 ;# create a section of two cylinders
428 checksection result ;# will output error message if result is bad
504a8968 431The test case can have any name (except for the reserved names *begin, end, data, cases.list* and *parse.rules*).
72b7576f 432For systematic grids it is usually a capital English letter followed by a number.

446@section testmanual_3 Creation And Modification Of Tests
448This section describes how to add new tests and update existing ones.
450@subsection testmanual_3_1 Choosing Group, Grid, and Test Case Name
504a8968 452The new tests are usually added in the frame of processing issues in OCCT Mantis tracker.
72b7576f 453Such tests in general should be added to group bugs, in the grid
67d7f07f 454corresponding to the affected OCCT functionality. See @ref testmanual_5_2 "Mapping of OCCT functionality to grid names in group bugs".
504a8968 455
456New grids can be added as necessary to contain tests for the functionality not yet covered by existing test grids.
457The 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 458
504a8968 462 bug12345_coaxial
463 bug12345_orthogonal_1
464 bug12345_orthogonal_2
72b7576f 465~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
504a8968 467If 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 468
469@subsection testmanual_3_2 Adding Data Files Required for a Test
ae3eaf7b 471It 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 472
ae3eaf7b 473If the test requires a data file, it should be put to the directory listed in environment variable *CSF_TestDataPath*.
936f43da 474Alternatively, it can be put to subdirectory *data* of the test grid.
475It 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 476
ae3eaf7b 477Note 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 478
ae3eaf7b 479When 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 480
482@subsection testmanual_3_3 Adding new DRAW commands
484If the test cannot be implemented using available DRAW commands, consider the following possibilities:
485* 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.
486* 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.
487* 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*.
489Note 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 490File names must be encoded in the script rather than in the DRAW command and passed to the DRAW command as an argument.
504a8968 491
492@subsection testmanual_3_4 Script Implementation
494The 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.
496Usually 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.
72b7576f 498Example:
504a8968 499~~~~~
500# Simple test of fusing box and sphere
501box b 10 10 10
502sphere s 5
503bfuse result b s
504checkshape result
72b7576f 506
504a8968 507Make 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.
509For instance, for catching errors reported by *checkshape* command relevant grids define a rule to recognize its report by the word *Faulty*:
512FAILED /\bFaulty\b/ bad shape
515For the messages generated in the script it is recommended to use the word 'Error' in the error message.
72b7576f 516
72b7576f 517Example:
504a8968 519~~~~~
520set expected_length 11
521if { [expr $actual_length - $expected_length] > 0.001 } {
522 puts "Error: The length of the edge should be $expected_length"
526At 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.
528When 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 529
72b7576f 530Example:
504a8968 532~~~~~
533stepread [locate_data_file CAROSKI_COUPELLE.step] a *
936f43da 536When the test needs to produce some snapshots or other artefacts, use Tcl variable *imagedir* as the location where such files should be put.
ae3eaf7b 537* Command *testgrid* sets this variable to the subdirectory of the results folder corresponding to the grid.
538* 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.
540However if variable *imagedir* is defined on the top level of Tcl interpretor, command *test* will use it instead of creating a new directory.
936f43da 541
542Use Tcl variable *casename* to prefix all files produced by the test.
543This variable is set to the name of the test case.
ae3eaf7b 544
545The 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.
936f43da 547The image format (defined by extension) should be *png*.
72b7576f 548
72b7576f 549Example:
504a8968 550~~~~~
936f43da 551xwd $imagedir/${casename}.png
504a8968 552vdisplay result; vfit
936f43da 553vdump $imagedir/${casename}-axo.png
504a8968 554vfront; vfit
936f43da 555vdump $imagedir/${casename}-front.png
504a8968 556~~~~~
72b7576f 557
504a8968 558would produce:
72b7576f 564
504a8968 565Note that OCCT must be built with FreeImage support to be able to produce usable images.
72b7576f 566
936f43da 567Other Tcl variables defined during the test execution are:
ae3eaf7b 568- *groupname*: name of the test group;
569- *gridname*: name of the test grid;
570- *dirname*: path to the root directory of the current set of test scripts.
936f43da 571
504a8968 572In order to ensure that the test works as expected in different environments, observe the following additional rules:
573* 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 574* 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 575* Do not use commands *decho* and *dlog* in the test script, to avoid interference with use of these commands by the test system.
72b7576f 576
dcc0a33e 577@subsection testmanual_details_results Interpretation of test results
72b7576f 578
504a8968 579The result of the test is evaluated by checking its output against patterns defined in the files *parse.rules* of the grid and group.
72b7576f 580
504a8968 581The OCCT test system recognizes five statuses of the test execution:
582* 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 583* 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.
584* 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 585* 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).
586* OK: reported if none of the above statuses have been assigned. This means that the test has passed without problems.
72b7576f 587
504a8968 588Other statuses can be specified in *parse.rules* files, these will be classified as FAILED.
72b7576f 589
504a8968 590For integration of the change to OCCT repository, all tests should return either OK or BAD status.
591The 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 592
504a8968 593@subsection testmanual_3_6 Marking BAD cases
72b7576f 594
ae3eaf7b 595If 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 596
504a8968 597The following statement should be added to such a test script:
599puts "TODO BugNumber ListOfPlatforms: RegularExpression"
603* *BugNumber* is the bug ID in the tracker. For example: #12345.
863f782a 604* *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 605
504a8968 607~~~~~
863f782a 608Draw[2]> checkplatform
504a8968 610~~~~~
72b7576f 611
ae3eaf7b 612* RegularExpression is a regular expression, which should be matched against the line indicating the problem in the script output.
72b7576f 613
72b7576f 614Example:
504a8968 615~~~~~
616puts "TODO #22622 Mandriva2008: Abort .* an exception was raised"
72b7576f 618
504a8968 619The 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 620
504a8968 621A 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.
623To 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 624
504a8968 627~~~~~
628puts "TODO OCC22817 All: exception.+There are no suitable edges"
629puts "TODO OCC22817 All: \\*\\* Exception \\*\\*"
630puts "TODO OCC22817 All: TEST INCOMPLETE"
72b7576f 632
6d368502 633@subsection testmanual_3_7 Marking required output
251a7984 635To check the obtained test output matches the expected results considered correct, add REQUIRED statement for each specific message.
636For that, the following statement should be added to the corresponding test script:
6d368502 637
639puts "REQUIRED ListOfPlatforms: RegularExpression"
642Here *ListOfPlatforms* and *RegularExpression* have the same meaning as in TODO statements described above.
251a7984 644The 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 645
b502ddc1 648puts "REQUIRED Linux: Faulty shapes in variables faulty_1 to faulty_5"
6d368502 649~~~~~
651This 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 652
6d368502 653If output does not contain required statement, test case will be marked as FAILED.
504a8968 654
655@section testmanual_4 Advanced Use
72b7576f 656
657@subsection testmanual_4_1 Running Tests on Older Versions of OCCT
ae3eaf7b 659Sometimes 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 660
504a8968 661Note: 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.
663For 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*):
666set env(CASROOT) d:/occt
667set env(CSF_TestScriptsPath) $env(CASROOT)/tests
668source $env(CASROOT)/src/DrawResources/TestCommands.tcl
669set env(CSF_TestDataPath) $env(CASROOT)/data;d:/test-data
ae3eaf7b 673Note 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 674
675@subsection testmanual_4_2 Adding custom tests
677You 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.
4ee1bdf4 679Use Tcl command <i>_path_separator</i> to insert a platform-dependent separator to the path list.
504a8968 680
681For example:
683set env(CSF_TestScriptsPath) \
684 $env(TestScriptsPath)[_path_separator]d:/MyOCCTProject/tests
685set env(CSF_TestDataPath) \
686 d:/occt/test-data[_path_separator]d:/MyOCCTProject/data
687return ;# this is to avoid an echo of the last command above in cout
690@subsection testmanual_4_3 Parallel execution of tests
692For better efficiency, on computers with multiple CPUs the tests can be run in parallel mode. This is default behavior for command *testgrid* : the tests are executed in parallel processes (their number is equal to the number of CPUs available on the system). In order to change this behavior, use option parallel followed by the number of processes to be used (1 or 0 to run sequentially).
72b7576f 693
87f42a3f 694Note that the parallel execution is only possible if Tcl extension package *Thread* is installed.
695If this package is not available, *testgrid* command will output a warning message.
72b7576f 696
504a8968 697@subsection testmanual_4_4 Checking non-regression of performance, memory, and visualization
72b7576f 698
504a8968 699Some test results are very dependent on the characteristics of the workstation, where they are performed, and thus cannot be checked by comparison with some predefined values. These results can be checked for non-regression (after a change in OCCT code) by comparing them with the results produced by the version without this change. The most typical case is comparing the result obtained in a branch created for integration of a fix (CR***) with the results obtained on the master branch before that change is made.
701OCCT test system provides a dedicated command *testdiff* for comparing CPU time of execution, memory usage, and images produced by the tests.
704testdiff dir1 dir2 [groupname [gridname]] [options...]
706Here *dir1* and *dir2* are directories containing logs of two test runs.
708Possible options are:
3f812249 709* <i>-save \<filename\> </i> -- saves the resulting log in a specified file (<i>$dir1/diff-$dir2.log</i> by default). HTML log is saved with the same name and extension .html;
710* <i>-status {same|ok|all}</i> -- allows filtering compared cases by their status:
711 * *same* -- only cases with same status are compared (default);
712 * *ok* -- only cases with OK status in both logs are compared;
713 * *all* -- results are compared regardless of status;
714* <i>-verbose \<level\> </i> -- defines the scope of output data:
715 * 1 -- outputs only differences;
716 * 2 -- additionally outputs the list of logs and directories present in one of directories only;
717 * 3 -- (by default) additionally outputs progress messages;
44fae8b1 718* <i>-image [filename]</i> - compare images and save the resulting log in specified file (<i>$dir1/diffimage-$dir2.log</i> by default)
719* <i>-cpu [filename]</i> - compare overall CPU and save the resulting log in specified file (<i>$dir1/diffcpu-$dir2.log</i> by default)
720* <i>-memory [filename]</i> - compare memory delta and save the resulting log in specified file (<i>$dir1/diffmemory-$dir2.log</i> by default)
721* <i>-highlight_percent \<value\></i> - highlight considerable (>value in %) deviations of CPU and memory (default value is 5%)
72b7576f 722
72b7576f 723Example:
504a8968 724
44fae8b1 726Draw[]> testdiff results/CR12345-2012-10-10T08:00 results/master-2012-10-09T21:20
729Particular tests can generate additional data that need to be compared by *testdiff* command.
730For 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.
732Example of test code:
735puts "COUNTER Memory heap usage at step 5: [meminfo h]"

5ae01c85 1040@subsection testmanual_5_3 Recommended approaches to checking test results
504a8968 1041
1042@subsubsection testmanual_5_3_1 Shape validity
1044Run 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.
1048checkshape result
5ae01c85 1051To check the number of faults in the shape command *checkfaults* can be used.
1053Use: checkfaults shape source_shape [ref_value=0]
1055The default syntax of *checkfaults* command:
1057checkfaults results a_1
1060The command will check the number of faults in the source shape (*a_1*) and compare it
1061with number of faults in the resulting shape (*result*). If shape *result* contains
1062more faults, you will get an error:
1064checkfaults results a_1
1065Error : Number of faults is 5
1067It is possible to set the reference value for comparison (reference value is 4):
1070checkfaults results a_1 4
1073If number of faults in the resulting shape is unstable, reference value should be set to "-1".
1074As a result command *checkfaults* will return the following error:
1077checkfaults results a_1 -1
1078Error : Number of faults is UNSTABLE
504a8968 1081@subsubsection testmanual_5_3_2 Shape tolerance
dcb359e0 1082
504a8968 1083The maximal tolerance of sub-shapes of each kind of the resulting shape can be extracted from output of tolerance command as follows:
1086set tolerance [tolerance result]
1087regexp { *FACE +: +MAX=([-0-9.+eE]+)} $tolerance dummy max_face
1088regexp { *EDGE +: +MAX=([-0-9.+eE]+)} $tolerance dummy max_edgee
1089regexp { *VERTEX +: +MAX=([-0-9.+eE]+)} $tolerance dummy max_vertex
5ae01c85 1092It is possible to use command *checkmaxtol* to check maximal tolerance of shape and compare it with reference value.
fb60057d 1094Use: checkmaxtol shape [options...]
5ae01c85 1095
1096Allowed options are:
dcb359e0 1097 * <i>-ref</i> -- reference value of maximum tolerance;
1098 * <i>-source</i> -- list of shapes to compare with;
1099 * <i>-min_tol</i> -- minimum tolerance for comparison;
1100 * <i>-multi_tol</i> -- tolerance multiplier.
5ae01c85 1101
5ae01c85 1102The default syntax of *checkmaxtol* command for comparison with the reference value:
fb60057d 1104checkmaxtol result -ref 0.00001
5ae01c85 1105~~~~~
1107There is an opportunity to compare max tolerance of resulting shape with max tolerance of source shape.
1108In the following example command *checkmaxtol* gets max tolerance among objects *a_1* and *a_2*.
1109Then it chooses the maximum value between founded tolerance and value -min_tol (0.000001)
1110and multiply it on the coefficient -multi_tol (i.e. 2):
fb60057d 1113checkmaxtol result -source {a_1 a_2} -min_tol 0.000001 -multi_tol 2
5ae01c85 1114~~~~~
1116If the value of maximum tolerance more than founded tolerance for comparison, the command will return an error.
fb60057d 1118Also, command *checkmaxtol* can be used to get max tolerance of the shape:
1121set maxtol [checkmaxtol result]
504a8968 1124@subsubsection testmanual_5_3_3 Shape volume, area, or length
1126Use command *vprops, sprops,* or *lprops* to correspondingly measure volume, area, or length of the shape produced by the test. The value can be extracted from the result of the command by *regexp*.
1130# check area of shape result with 1% tolerance
1131regexp {Mass +: +([-0-9.+eE]+)} [sprops result] dummy area
1132if { abs($area - $expected) > 0.1 + 0.01 * abs ($area) } {
1133 puts "Error: The area of result shape is $area, while expected $expected"
1137@subsubsection testmanual_5_3_4 Memory leaks
dcb359e0 1139The test system measures the amount of memory used by each test case. Considerable deviations (as well as the overall difference) in comparison with reference results can be reported by command *testdiff* (see @ref testmanual_4_4).
504a8968 1140
dcb359e0 1141To check memory leak on a particular operation, run it in a cycle, measure the memory consumption at each step and compare it with a threshold value.
1142The command *checktrend* (defined in *tests/bugs/begin*) can be used to analyze a sequence of memory measurements and to get a statistically based evaluation of the leak presence.
504a8968 1143
1146set listmem {}
1147for {set i 1} {$i < 100} {incr i} {
1148 # run suspect operation
1150 # check memory usage (with tolerance equal to half page size)
1151 lappend listmem [expr [meminfo w] / 1024]
1152 if { [checktrend $listmem 0 256 "Memory leak detected"] } {
1153 puts "No memory leak, $i iterations"
1154 break
1155 }
1159@subsubsection testmanual_5_3_5 Visualization
dcb359e0 1161The 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 1162
1166vdisplay result
1167vsetdispmode 1
1170vdump $imagedir/${casename}_shading.png
1173This 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 1174
5747059b 1175Also it is possible to use command *checkview* to make a snapshot of the viewer.
1177Use: checkview [options...]

1182* <i>-path PATH</i> -- sets the location of the saved viewer screenshot;
1183* <i>-vdispmode N</i> -- sets *vdispmode* for 3d viewer (default value is 1)
1184* <i>-screenshot</i> -- makes a screenshot of already created viewer
1185* The procedure can check a property of shape (length, area or volume) and compare it with value *N*:
1186 * <i>-l [N]</i>
1187 * <i>-s [N]</i>
1188 * <i>-v [N]</i>
1189 * If the current property is equal to value *N*, the shape is marked as valid in the procedure.
1190 * If value *N* is not given, the procedure will mark the shape as valid if the current property is non-zero.
1191* <i>-with {a b c}</i> -- displays shapes *a, b* and *c* together with the shape (if the shape is valid)
1192* <i>-otherwise {d e f}</i> -- displays shapes *d, e* and *f* instead of the shape (if the shape is NOT valid)
1194Note that is required to use either option <i> -2d </i> or option <i> -3d</i>.

5ae01c85 1221@subsubsection testmanual_5_3_6 Number of free edges
dcb359e0 1223Procedure *checkfreebounds* compares the number of free edges with a reference value.
5ae01c85 1224
1225Use: checkfreebounds shape ref_value [options...]
1227Allowed options are:
dcb359e0 1228 * <i>-tol N</i> -- used tolerance (default -0.01);
1229 * <i>-type N</i> -- used type, possible values are "closed" and "opened" (default "closed").

1232checkfreebounds result 13
dcb359e0 1235Option <i>-tol N</i> defines tolerance for command *freebounds*, which is used within command *checkfreebounds*.
5ae01c85 1236
dcb359e0 1237Option <i>-type N</i> is used to select the type of counted free edges: closed or open.
5ae01c85 1238
dcb359e0 1239If the number of free edges in the resulting shape is unstable, the reference value should be set to "-1".
5ae01c85 1240As a result command *checkfreebounds* will return the following error:
1243checkfreebounds result -1
1244Error : Number of free edges is UNSTABLE
