// This comment contains the central documentation for how we configured Jetpack Benchmark. Currently:
|
|
// - microbenchmark: configured differently than recommended (see inline notes below)
|
|
// - macrobenchmark: not configured
|
|
//
|
|
// To run our benchmarks, you need to set the "benchmark" gradle property. You can:
|
|
// - (preferred) Run via the command line (change the class you run on):
|
|
// ./gradlew -Pbenchmark app:connectedCheck -Pandroid.testInstrumentationRunnerArguments.class=org.mozilla.fenix.perf.SampleBenchmark
|
|
// - Use the IDE. Temporarily set the "benchmark" property in app/build.gradle with "ext.benchmark=true"
|
|
// near the top of the file. DO NOT COMMIT THIS.
|
|
// - (note: I was unable to get IDE run configurations working)
|
|
//
|
|
// To get the results, look at this file (we recommend using the median; results are in nanoseconds):
|
|
// app/build/outputs/connected_android_test_additional_output/nightlyAndroidTest/connected/<device>/org.mozilla.fenix-benchmarkData.json
|
|
//
|
|
// I was unable to get the results to print directly in Android Studio (perhaps it's my device).
|
|
//
|
|
// The official documentation suggests configuring microbenchmark in a separate module. This would
|
|
// require any benchmarked code to be in a library module, not the :app module (see below). To avoid
|
|
// this requirement, we created the "benchmark" gradle property.
|
|
//
|
|
// For the most accurate results, the documentation recommends running tests on rooted devices with
|
|
// the CPU clock locked.
|
|
//
|
|
// See https://developer.android.com/studio/profile/benchmark#what-to-benchmark for when writing a
|
|
// jetpack microbenchmark is a good fit.
|
|
|
|
// I think `android` represents this object:

// The official documentation https://developer.android.com/studio/profile/benchmark#full-setup
|
|
// recommends setting up the Microbenchmark library in a separate module from your app: AFAICT,
|
|
// the reason for this is to prevent the benchmarks from being configured against debug
|
|
// builds. We chose not to do this because it's a lot of work to pull code out into a
|
|
// separate module just to benchmark it. We were able to replicate the outcome by setting
|
|
// this testBuildType property.

|
|
// "IsolationActivity" to reduce the impact of other work on the device from affecting the benchmark
|
|
// and to opt into a lower-max CPU frequency on unrooted devices that support it
|
|
// - UNLOCKED: ./gradlew lockClocks, which locks the CPU frequency, fails on my device. See
|
|
// https://issuetracker.google.com/issues/176836267 for potential workarounds.
