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.
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_HOME=$(ls -d ~/android-ndk-*) # Or wherever you installed the Android NDK.
Install the Android SDK. Set the ANDROID_HOME
environment variable.
mkdir ~/android-sdk ( cd ~/android-sdk; unzip ~/Downloads/sdk-tools-*.zip ) yes | ~/android-sdk/tools/bin/sdkmanager --licenses export ANDROID_HOME=~/android-sdk # Or wherever you installed the Android SDK.
Put adb
in your PATH
.
export PATH="${PATH}:${ANDROID_HOME}/platform-tools"
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
Build the APK:
tools/git-sync-deps tools/skqp/make_universal_apk
Build, install, and run.
adb install -r out/skqp/skqp-universal-debug.apk adb logcat -c adb shell am instrument -w org.skia.skqp
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"
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
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
Follow steps 1-3 as above.
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
