# ANGLE + dEQP

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](DevSetup.md)
instructions. Current targets:

* `angle_deqp_gles2_tests` for GLES 2.0 tests
* `angle_deqp_gles2_no_gtest` for GLES 2.0 tests without google test suite
* `angle_deqp_gles3_tests` for GLES 3.0 tests
* `angle_deqp_gles3_no_gtest` for GLES 3.0 tests without google test suite
* `angle_deqp_egl_tests` for EGL 1.x tests
* `angle_deqp_egl_no_gtest` for EGL 1.x tests without google test suite
* `angle_deqp_gles31_tests` for GLES 3.1 tests (currently very experimental)
* `angle_deqp_gles31_no_gtest` for GLES 3.1 tests (currently very experimental) without google test suite

## How to use dEQP

Note:
To run an individual test, use the `--deqp-case` flag on any of the `no_gtest` targets.
It supports simple wildcard support. For example: `--deqp-case=dEQP-
GLES2.functional.shaders.linkage.*`.
The `gtest` targets support wildcards via the `--gtest_filter` argument,
but have different test names.

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)
* `--deqp-egl-display-type=angle-vulkan` for Vulkan (Android, Linux, Windows)

### Check your results

If run from Visual Studio 2015, dEQP generates a test log to
`out/sln/obj/src/tests/TestResults.qpa`. To view the test log information, you'll need to
use the open-source GUI
[Cherry](https://android.googlesource.com/platform/external/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](https://android.googlesource.com/platform/external/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!
