SkQP

SkQP (Skia Quality Program) is a component of the Android CTS (Compatablity Test Suite) that tests an Android device's GPU and OpenGLES & Vulkan drivers using Skia's existing unit & rendering tests.

See https://skia.org/dev/testing/skqp for pre-build APKs.

How to build and run the SkQP tests

  1. Get the dependencies:

    • You will need Java JDK 8, git, and python.

    • Install Chromium's depot_tools. Add it to your PATH.

      git clone 'https://chromium.googlesource.com/chromium/tools/depot_tools.git'
export PATH="${PWD}/depot_tools:${PATH}"

    • Install the Android NDK.

      ( cd ~; unzip ~/Downloads/android-ndk-*.zip )
ANDROID_NDK=$(ls -d ~/android-ndk-*)   # Or wherever you installed the Android NDK.

    • Install the Android SDK. Set the ANDROID_HOME environment variable.

      mkdir ~/android-sdk
( cd ~/android-sdk; unzip ~/Downloads/sdk-tools-*.zip )
yes | ~/android-sdk/tools/bin/sdkmanager --licenses
export ANDROID_HOME=~/android-sdk  # Or wherever you installed the Android SDK.

      Put adb in your PATH.

      export PATH="${PATH}:${ANDROID_HOME}/platform-tools"

  2. Get the right version of Skia:

    git clone https://skia.googlesource.com/skia.git
cd skia
git checkout origin/skqp/dev  # or whatever release tag you need

  3. Build the APK:

    tools/git-sync-deps
tools/skqp/make_universal_apk

  4. Build, install, and run.

    adb install -r out/skqp/skqp-universal-debug.apk
adb logcat -c
adb shell am instrument -w org.skia.skqp

  5. Monitor the output with:

    adb logcat TestRunner org.skia.skqp skia "*:S"

    Note the test's output path on the device. It will look something like this:

    01-23 15:22:12.688 27158 27173 I org.skia.skqp:
output written to "/storage/emulated/0/Android/data/org.skia.skqp/files/output"

  6. Retrieve and view the report with:

    OUTPUT_LOCATION="/storage/emulated/0/Android/data/org.skia.skqp/files/output"
adb pull $OUTPUT_LOCATION /tmp/
bin/sysopen /tmp/output/skqp_report/report.html

Running a single test

To run a single test, for example gles_aarectmodes:

adb shell am instrument -e class 'org.skia.skqp.SkQPRunner#gles_aarectmodes' -w org.skia.skqp

Unit tests can be run with the unitTest_ prefix:

adb shell am instrument -e class 'org.skia.skqp.SkQPRunner#unitTest_GrSurface -w org.skia.skqp

Run as a non-APK executable

  1. Follow steps 1-3 as above.

  2. Build the SkQP program, load files on the device, and run skqp:

    ninja -C out/skqp/arm skqp
python tools/skqp/run_skqp_exe out/skqp/arm
