Note that + this will also leave the android emulator running, so repeating the command will be + even faster the next time around as it won't need to redownload the AVDs or restart + the emulator. It will reinstall the APK and re-push the reftests folder though. + + If you want to use a release APK (runs much faster), build it as per the "Release mode" + instructions above and set the WRENCH_APK env var to point to the APK: + to point to it: + export WRENCH_APK=gfx/wr/target/release/apk/wrench.apk + ./mach python testing/mozharness/scripts/android_wrench.py --config testing/mozharness/configs/android/wrench.py + +Running reftests like a boss (on a local device): +------------------------------------------------- + + Same steps as running on a local emulator, except you need to do this: + export DEVICE_SERIAL=<your device's serial> + before running the `./mach python` command. You can get the serial of + your device by running `adb devices` with the device plugged in.
