Autobenchmark

Gradle Plugin

A Gradle plugin to automate macro-benchmark on baseline profile. Run your macro-benchmark tests for profile verification on Firbase test lab and verify benchmark result JSON. With this plugin it is possible to integrate baseline profile verification in your CI pipeline to fully automate baseline profile.

For generating profile you can leverage the official baseline profile gradle plugin. This plugin closes the loop of automating baseline profile end to end by providing automation on profile verification.

For more information on benchmarking baseline profile visit official Android guide.

Applying plugin

Using plugin DSL

Apply plugin to app module build.gradle.kts file.

plugins {
  id("io.github.sagar-viradiya.autobenchmark") version "1.0.0.alpha02"
}

Using legacy plugin application

Add this to top project level build.gradle.kts

buildscript {
  repositories {
    maven {
      url = uri("https://plugins.gradle.org/m2/")
    }
  }
  dependencies {
    classpath("io.github.sagar-viradiya:autobenchmark:1.0.0.alpha02")
  }
}

And then apply plugin to app module build.gradle.kts file.

apply(plugin = "io.github.sagar-viradiya.autobenchmark")

⚙️ Configuring plugin

Since it is recommended to run macro-benchmark on a physical device this plugin supports running tests on Firebase test lab through Fladle. Following are the mandatory parameters that you need to configure.

autoBenchmark {
    // A relative file path from the root to app apk with baseline profile
    appApkFilePath.set("/sample/build/outputs/apk/benchmark/sample-benchmark.apk")
    // A relative file path from the root to benchmark apk
    benchmarkApkFilePath.set("/benchmark/build/outputs/apk/benchmark/benchmark-benchmark.apk")
    // Service account JSON file path to authenticate GCloud
    serviceAccountJsonFilePath.set("../../.config/gcloud/application_default_credentials.json")
    // Physical device configuration map to run benchmark
    physicalDevices.set(mapOf(
        "model" to "redfin", "version" to "30"
    ))
    // Tolerance percentage for improvement below which verification will fail
    tolerancePercentage.set(10f)
}

🔐 Authenticate G-Cloud to run tests on Firebase test lab

To run tests on Firebase test lab and download JSON result of profile verification, you need to authenticate to G-Cloud.

Authenticating on local machine

  1. Run ./gradlew flankAuth
  2. Sign in to web browser.

This will store credentials in ~/.flank directory

Authenticating on CI

You will need service account JSON file to setup authentication on CI. Follow the test lab docs to create a service account. Base64 encode this file on your local machine and set this as environment variable on CI as GCLOUD_KEY.

base64 -i "$HOME/.config/gcloud/application_default_credentials.json" | pbcopy

Then on CI decode the JSON.

GCLOUD_DIR="$HOME/.config/gcloud/"
mkdir -p "$GCLOUD_DIR"
echo "$GCLOUD_KEY" | base64 --decode > "$GCLOUD_DIR/application_default_credentials.json"

Please refer to GitHub action setup to know how this is being done.

For more info refer this flank guide for authentication as this plugin internally uses Fladle and Flank

📈 Running benchmark tests and baseline profile verification

To run benchmark and verify result run following gradle task.

./gradlew [your_app]:runBenchmarkAndVerifyProfile

First, this will run all benchmark tests on Firebase test lab, and it will download benchmark result JSON from G-Cloud. This JSON file will be analysed next to compare 'No compilation median startup time' with 'baseline profile median startup time'. If the improvement percentage is below provided tolerancePercentage then gradle task will fail.

For example, if no compilation median startup is 233 ms and baseline profile median startup is 206 ms then startup time is improved by ~11%. If the provided tolerance percentage is 10 then task will successfully complete.

Task will also print improvement percentage, no compilation startup time median, and baseline profile startup time median.

> Task :sample:runBenchmarkAndVerifyProfile
No compilation median : 233.609398
Baseline profile median : 206.635229
Improvement percentage : 11.546700

BUILD SUCCESSFUL in 2m 35s
9 actionable tasks: 3 executed, 6 up-to-date

Note : One important requirement for benchmark result JSON parsing to work properly is to have 'NoCompilation' in the test name targeting no compilation mode, and 'BaselineProfile' in the test name targeting baseline profile mode.

Sample

Please refer to sample app to see the plugin setup. Before you issue ./gradlew :sample:runBenchmarkAndVerifyProfile you need to, build sample apk and benchmark apk first.

Run following commands to build apks

./gradlew :sample:assembleBenchmark
./gradlew :benchmark:assembleBenchmark

Also make sure to have service account JSON file in the configured path (serviceAccountJsonFilePath)

For verifying profile on CI, please refer to GitHub action setup.
