Running regression tests:
|
|
-------------------------
|
|
|
|
Prerequisites: cmake, python, ImageMagick 6.5.9.3 or newer
|
|
|
|
A) Building test environment
|
|
|
|
Linux, Mac:
|
|
$ cd tests
|
|
$ cmake .
|
|
$ make
|
|
|
|
Windows + MSVC:
|
|
|
|
First, get a normal build working by following instructions at
|
|
http://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Building_on_Windows
|
|
Then, from the QT command prompt:
|
|
|
|
> cd tests
|
|
> cmake . -DCMAKE_BUILD_TYPE=Release
|
|
> sed -i s/\/MD/\/MT/ CMakeCache.txt
|
|
> cmake .
|
|
> nmake -f Makefile
|
|
|
|
Cross compiling Linux->Win32:
|
|
|
|
Please see openscad/tests/CMingw-cross-env.cmake for instructions.
|
|
|
|
B) Running tests
|
|
|
|
$ ctest Runs tests enabled by default
|
|
$ ctest -R <regex> Runs only matching tests, e.g. ctest -R dxf
|
|
$ ctest -C <configs> Adds extended tests belonging to configs.
|
|
Valid configs:
|
|
Default - Run default tests
|
|
Heavy - Run more time consuming tests (> ~10 seconds)
|
|
Examples - test all examples
|
|
All - test everything
|
|
|
|
Adding a new regression test:
|
|
------------------------------
|
|
|
|
1) create a test file at an appropriate location under testdata/
|
|
2) if the test is non-obvious, create a human readable description as comments in the test (or in another file in the same directory in case the file isn't human readable)
|
|
3) if a new test app was written, this must be added to tests/CMakeLists.txt
|
|
4) Add the tests to the test apps for which you want them to run (in tests/CMakeLists.txt)
|
|
5) run the test with the environment variable TEST_GENERATE=1, e.g.:
|
|
$ TEST_GENERATE=1 ctest -R mytest
|
|
(this will generate a mytest-expected.txt file which is used for regression testing)
|
|
6) manually verify that the output is correct (tests/regression/<testapp>/mytest-expected.<suffix>)
|
|
7) run the test normally and verify that it passes:
|
|
$ ctest -R mytest
|
|
|
|
Troubleshooting:
|
|
------------------------------
|
|
|
|
0. Headless unix servers
|
|
|
|
If you are attempting to run the tests on a unix-like system but only
|
|
have shell-console access, you may be able to run the tests by using a
|
|
virtual framebuffer program like Xvnc or Xvfb. For example:
|
|
|
|
$ Xvfb :5 -screen 0 800x600x24 &
|
|
$ DISPLAY=:5 ctest
|
|
|
|
Some versions of Xvfb may fail, however.
|
|
|
|
1. Trouble finding libraries on unix
|
|
|
|
To help CMAKE find eigen2, OpenCSG, CGAL, Boost, and GLEW, you can use
|
|
environment variables, just like for the main qmake & openscad.pro. Examples:
|
|
|
|
OPENSCAD_LIBRARIES=~ cmake .
|
|
CGALDIR=~/CGAL-3.9 BOOSTDIR=~/boost-1.47.0 cmake .
|
|
|
|
Valid variables are as follows:
|
|
|
|
BOOSTDIR, CGALDIR, EIGEN2DIR, GLEWDIR, OPENCSGDIR, OPENSCAD_LIBRARIES
|
|
|
|
2. Location of logs
|
|
|
|
Logs of test runs are found in tests/build/Testing/Temporary
|
|
A pretty-printed index.html is in a subdir of tests/build/Testing/Temporary
|
|
Expected results are found in tests/regression/*
|
|
Actual results are found in tests/build/testname-output/*
|
|
|
|
3. Image-based tests takes a long time, they fail, and the log says 'return -11'
|
|
|
|
Imagemagick may have crashed while comparing the expected images to the
|
|
test-run generated (actual) images. You can try using the alternate
|
|
ImageMagick comparison method by by erasing CMakeCache, and re-running
|
|
cmake with -DCOMPARATOR=ncc. This will enable the Normalized Cross
|
|
Comparison method.
|
|
|
|
4. Testing images fails with 'morphology not found" for ImageMagick in the log
|
|
|
|
Your version of imagemagick is old. Upgrade, or pass -DCOMPARATOR=old to
|
|
cmake. The comparison will be of lowered reliability.
|
|
|
|
