/**
* This test class benchmarks the speed of app startup.
* Run this benchmark to verify how effective a Baseline Profile is.
* It does this by comparing [CompilationMode.None], which represents the app with no Baseline
* Profiles optimizations, and [CompilationMode.Partial], which uses Baseline Profiles.
*
* Run this benchmark to see startup measurements and captured system traces for verifying
* the effectiveness of your Baseline Profiles. You can run it directly from Android
* Studio as an instrumentation test, or run all benchmarks for a variant, for example benchmarkRelease,
* with this Gradle task:
* ```
* ./gradlew :baselineprofile:connectedBenchmarkReleaseAndroidTest
* ```
*
* You should run the benchmarks on a physical device, not an Android emulator, because the
* emulator doesn't represent real world performance and shares system resources with its host.
*
* For more information, see the [Macrobenchmark documentation](https://d.android.com/macrobenchmark#create-macrobenchmark)
* and the [instrumentation arguments documentation](https://d.android.com/topic/performance/benchmarking/macrobenchmark-instrumentation-args).
