+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](http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html). 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](https://developer.android.com/ndk/downloads/).
+
+ ( cd ~; unzip ~/Downloads/android-ndk-*.zip )
+ ANDROID_NDK=$(ls -d ~/android-ndk-*) # Or wherever you installed the Android NDK.
+
+ - Install the [Android SDK](https://developer.android.com/studio/#command-tools).
+ Set the `ANDROID_HOME` environment variable.
+
+ mkdir ~/android-sdk
+ ( cd ~/android-sdk; unzip ~/Downloads/sdk-tools-*.zip )
+ yes | ~/android-sdk/tools/bin/sdkmanager --licenses
+ export ANDROID_HOME=~/android-sdk # Or wherever you installed the Android SDK.
+
+ Put `adb` in your `PATH`.
+
+ export PATH="${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:
+
+ gn gen out/skqp-arm
+ ninja -C out/skqp-arm skqp
+ python tools/skqp/run_skqp_exe out/skqp-arm
+
