## Window manager performance tests
### Precondition
To reduce the variance of the test, if `perf-setup.sh` (platform_testing/scripts/perf-setup)
is available, it is better to use the following instructions to lock CPU and GPU frequencies.
```
m perf-setup
PERF_SETUP_PATH=/data/local/tmp/perf-setup.sh
adb push $OUT/$PERF_SETUP_PATH $PERF_SETUP_PATH
adb shell chmod +x $PERF_SETUP_PATH
adb shell $PERF_SETUP_PATH
```
### Example to run
Use `atest`
```
atest WmPerfTests:RelayoutPerfTest -- \
--module-arg WmPerfTests:instrumentation-arg:kill-bg:=true
```
Use `am instrument`
```
adb shell am instrument -w -r -e class android.wm.RelayoutPerfTest \
-e listener android.wm.WmPerfRunListener \
-e kill-bg true \
com.android.perftests.wm/androidx.test.runner.AndroidJUnitRunner
```
* `kill-bg` is optional.
Test arguments
- kill-bg
* boolean: Kill background process before running test.
- profiling-iterations
* int: Run the extra iterations with enabling method profiling.
- profiling-sampling
* int: The interval (0=trace each method, default is 10) of sample profiling in microseconds.
