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.

How to 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 ~/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. Download dependencies, the model, and configure the build. (If you want to test another architecture, replace arm with x86, x64, or arm64.)

   python tools/skqp/download_model
   python tools/skqp/setup_resources
   python tools/git-sync-deps
   python tools/skqp/generate_gn_args out/skqp-arm "$ANDROID_NDK" arm
   bin/gn gen out/skqp-arm
   

4. Build, install, and run.

   platform_tools/android/bin/android_build_app -C out/skqp-arm skqp
   adb install -r out/skqp-arm/skqp.apk
   adb logcat -c
   adb shell am instrument -w org.skia.skqp/android.support.test.runner.AndroidJUnitRunner
   

5. Monitor the output with:

   adb logcat 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/
   tools/skqp/sysopen.py /tmp/output/skqp_report/report.html
   

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
