drawElements (dEQP) is a very robust and comprehensive set of open-source tests for GLES2, GLES3+ and EGL. They provide a huge net of coverage for almost every GL API feature. ANGLE by default builds dEQP testing targets for testing with GLES 2 with D3D9/11 and OpenGL, and GLES 3 with D3D11.
You should have dEQP as a target if you followed the DevSetup instructions. There are two executables, angle_deqp_gles2_tests and angle_deqp_gles3_tests.
Currently we only support Windows platforms.
Running the full test suite in Debug can take a very long time. We recommend first dumping the complete lists of tests to a text file, then running the tests that apply to your changes.
To dump a list of test cases, append the command line arguments --deqp-runmode=txt-caselist, run the GLES2 or GLES3 target, then look for the file named src\tests\third_party\deqp\data\dEQP-GLES2-cases.txt. (Or GLES3).
Scan the case list files for tests with names similar to the features you're working on. Then, to run particular tests, use the command line arguments --deqp-case=dEQP-GLES2.functional.shaders.linkage.* (for example). Replace the test name string with the test your want from the case list files you dumped above.
By default the tests run on ANGLE D3D11. To specify the exact platform for ANGLE + dEQP, use the arguments:
--deqp-egl-native-display-type=angle-d3d11 for D3D11 (high feature level)--deqp-egl-native-display-type=angle-d3d9 for D3D9--deqp-egl-native-display-type=angle-d3d11-fl93 for D3D11 Feature level 9_3--deqp-egl-native-display-type=angle-gl for OpenGLFor now, the recommended practice is to manually compare your passes/failures with the results prior to your modifications.
dEQP uses the open-source GUI Cherry for viewing batch test results (see the TestResults.qpa file). ANGLE doesn't currently build or distribute Cherry, but feel free to check it out!
