/**
|
|
* This test class generates a basic startup baseline profile for the target package.
|
|
*
|
|
* Refer to the [baseline profile documentation](https://d.android.com/topic/performance/baselineprofiles)
|
|
* for more information.
|
|
*
|
|
* Make sure `autosignReleaseWithDebugKey=true` is present in local.properties.
|
|
*
|
|
* Generate the baseline profile using this gradle task:
|
|
* ```
|
|
* ./gradlew :benchmark:pixel6Api34BenchmarkAndroidTest -P android.testInstrumentationRunnerArguments.class=org.mozilla.fenix.benchmark.baselineprofile.StartupOnlyBaselineProfileGenerator -P benchmarkTest -P disableOptimization
|
|
* ```
|
|
*
|
|
* Check [documentation](https://d.android.com/topic/performance/benchmarking/macrobenchmark-instrumentation-args)
|
|
* for more information about available instrumentation arguments.
|
|
*
|
|
* As the experiment is only for nightly, run
|
|
* ```
|
|
* ./gradlew copyBaselineProfile
|
|
* ```
|
|
* This will copy the baseline profiles to the nightly folder. These are the profiles that will be compiled with the nightly build.
|
|
*
|
|
* Then, copy the profiles to app/src/benchmark/baselineProfiles to verify the improvements by running
|
|
* the [org.mozilla.fenix.benchmark.BaselineProfilesStartupBenchmark] benchmark.
|
|
* Notice that when we run the benchmark, we run the benchmark variant and not the nightly so copying the profiles here is important.
|
|
* These shouldn't be pushed to version control.
|
|
*
|
|
* When using this class to generate a baseline profile, only API 33+ or rooted API 28+ are supported.
