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 against GLES 2, GLES 3, EGL, and GLES 3.1 (on supported platforms).

How to build dEQP

You should have dEQP as a target if you followed the DevSetup instructions. Current targets:

  • angle_deqp_gles2_tests for GLES 2.0 tests
  • angle_deqp_gles3_tests for GLES 3.0 tests
  • angle_deqp_egl_tests for EGL 1.x tests
  • angle_deqp_gles31_tests for GLES 3.1 tests (currently very experimental)

How to use dEQP

The --deqp-case flag allows you to run individual tests, with simple wildcard support. For example: --deqp-case=dEQP- GLES2.functional.shaders.linkage.*.

The tests lists are sourced from the Android CTS masters in third_party/deqp/src/android/cts/master. See gles2-master.txt, gles3-master.txt, gles31-master.txt and egl-master.txt.

If you're running a full test suite, it might take very long time. Running in Debug is only useful to isolate and fix particular failures, Release will give a better sense of total passing rate.

Choosing a Renderer on Windows

By default Windows ANGLE tests with D3D11. To specify the exact platform for ANGLE + dEQP, use the arguments:

  • --deqp-egl-display-type=angle-d3d11 for D3D11 (highest available feature level)
  • --deqp-egl-display-type=angle-d3d9 for D3D9
  • --deqp-egl-display-type=angle-d3d11-fl93 for D3D11 Feature level 9_3
  • --deqp-egl-display-type=angle-gl for OpenGL Desktop (OSX, Linux and Windows)
  • --deqp-egl-display-type=angle-gles for OpenGL ES (Android/ChromeOS, some Windows platforms)

Check your results

If run from Visual Studio 2015, dEQP generates a test log to src/tests/TestResults.qpa. To view the test log information, you'll need to use the open-source GUI Cherry. ANGLE checks out a copy of Cherry to angle/third_party/cherry when you sync with gclient. Note, if you are using ninja or another build system, the qpa file will be located in your working directory.

See the [official Cherry README]( ernal/cherry/+/master/README) for instructions on how to run Cherry on Linux or Windows.

GoogleTest, ANGLE and dEQP

ANGLE also supports the same set of targets built with GoogleTest, for running on the bots. We don't currently recommend using these for local debugging, but we do maintain lists of test expectations in src/tests/deqp_support. When you fix tests, please remove the suppression(s) from the relevant files!
