# Testing in KWin
|
||
|
|
KWin provides a unit and integration test suite for X11 and Wayland. The source code for the tests can be found in the subdirectory autotests. The test suite should be run prior to any merge to KWin.
|
||
|
|
|
||
|
|
# Dependencies
|
||
|
|
The following additional software needs to be installed for running the test suite:
|
||
|
|
|
||
|
|
* Xvfb
|
||
|
|
* Xephyr
|
||
|
|
* glxgears
|
||
|
|
* DMZ-white cursor theme
|
||
|
|
* breeze window decoration
|
||
|
|
|

# Preparing OpenGL
|
||
|
|
Some of the tests require OpenGL. The test suite is implemented against Mesa and uses the Mesa specific EGL extension
|
||
|
|
EGL_MESA_platform_surfaceless. This extension supports rendering without any real GPU using llvmpipe as software
|
||
|
|
emulation. This gives the tests a stable base removing variance introduced by different hardware and drivers.
|
||
|
|
|
||
|
|
Users of non-Mesa drivers (e.g. proprietary NVIDIA driver) need to ensure that Mesa is also installed. If your system
|
||
|
|
uses libglvnd this should work out of the box, if not you might need to tune LD_LIBRARY_PATH.
|
||
|
|
|
||
|
|
# Running the test suite
|
||
|
|
The test suite can be run from the build directory. Best is to do:
|
||
|
|
|
||
|
|
cd path/to/build/directory
|
||
|
|
xvfb-run ctest
|
||
|
|
|
||
|
|
# Running individual tests
|
||
|
|
All tests executables are created in the directory "bin" in the build directory. Each test can be executed by just starting it from within the test directory. To prevent side effects with the running session it is recommended to start a dedicated dbus session:
|
||
|
|
|
||
|
|
cd path/to/build/directory/bin
|
||
|
|
dbus-run-session ./testFoo
|
||
|
|
|
||
|
|
For tests relying on X11 one should also either start a dedicated Xvfb and export DISPLAY or use xvfb-run as described above.
