Gra-Fi-Te Leveraging Gradle and Firebase for Android Testing Santosh Astagi Rally Health 

Gradlew wrapper - ./gradlew 

Gradle tasks - ./gradlew tasks 

Android plugin for gradle - com.android.tools.build:gradle:#.#.# Android tasks Build tasks Install tasks Verification tasks - Testing tasks 

Unit tests - test Running all tests - ./gradlew test Running all tests for a flavor - ./gradlew test{flavor}UnitTest Running individual tests - ./gradlew test{flavor}UnitTest\ —tests {packageName}.{testMethodName} Wild cards - ./gradlew test{flavor}UnitTest\ —tests *includedTestTitle* 

Instrumentation tests - androidTest Running all tests - ./gradlew connectedAndroidTest OR cAT Running a specific test - ./gradlew connectedAndroidTest\ -Pandroid.testInstrumentationRunnerArguments.class\ ={package name}.{class name}#{method name} GOTCHA - testCoverage, orchestrator:1.0.2 with gradle plugin <3.2 android plugin - 3.3.0+, gradle version - 4.9 

Filtering tests - Annotations @SmallTest - < 100ms, unit tests ./gradlew connectedAndroidTest\ -Pandroid.testInstrumentationRunnerArguments.size\ =Large @MediumTest - < 2s, every checkin, avoid blocking operations @LargeTest - <120s, Atleast once a day, all external communications 

testOptions{} - Android Plugin DSL Reference Specify reportDir, resultsDir testBuildType to change default from debug unitTests {…} (Possible additions below) includeAndroidResources true returnDefaultValues true 

Coverage reports testCoverageEnabled true ./gradlew createDebugCoverageReport apply plugin: "jacoco" Coverage report: jacoco/test{flavor}UnitTest.exec 

Gradle tasks task taskname( ) { } Copy from "origin" into "destination" Gradle DSL method not found: 'from()' type: 

Gradle tasks task taskname( ) type: //Pre built task description: //Meaningful enough dependsOn: //task to be executed before group: //E.g. verification, install ./gradlew taskName -PpropertyName=propertyValue project.hasProperty(“propertyName”) project.property(“propertyName”) 

Unified reports task unifiedReport( type: JacocoReport, dependsOn: ['testDebugUnitTest'], ‘createDebugCoverageReport’] ) { sourceDirectories = files(coverageSourceDirs) classDirectories = files([javaClasses], [kotlinClasses]) executionData = fileTree(dir: project.projectDir, includes: [“coverage.exec”, “testDebugUnitTest.exec”) 

Unified reports task unifiedReport( type: JacocoReport, dependsOn: ['testDebugUnitTest'] ) { } reports { xml.enabled = true html.enabled = true } /build/reports/jacoco/…

Robolectric tests coverage Prior 3.0 plugin, jacoco node in unitTests block Search for tasks of type test tasks.withType(Test) { jacoco.includeNoLocationClasses = true } } 

Kotlin data classes 

Jacoco snapshot build https://oss.sonatype.org/content/repositories/snapshots project.jacoco { toolVersion = '0.8.2-SNAPSHOT' } 

Multi module apps 

app models networking ext.jacocoReport = {Project project, String variant -> } jacocoReport(project, ‘debug’) jacocoReport(project, ‘debug’) jacocoReport(project, ‘debug’) 

Gradle methods ext.jacocoTestReport = {Project project, String variant -> } jacocoTestReport(project, ‘flavorName’) project.tasks.create( name: ‘jacocoTestReport’ ) { } 

Combining reports apply plugin: ‘android-reporting’ ./gradlew connectedAndroidTest mergeAndroidReports {root project}/build/reports ./gradlew createDebugCoverageReport mergeAndroidReports 

Unified reporting root level gradle task Update coverage directories using $rootProject Update class directories using $rootProject /build/reports/jacoco/… 

Cloud testing 

Cloud testing Firebase testlab, Saucelabs, Genymotion, Amazon, Xamarin etc. Firebase testlab beta for iOS announced at I/O 18 Firebase - wide range of devices and emulators 

Testlab - options, useful configurations - -timeout - max. time this execution can run (timeout code sent back) - - performance-metrics - CPU usage, network usage, FPS - - results-bucket - Specify gcloud bucket Specific exit codes to play nicely with scripts 

Firebase console - using reports Stored in Google Cloud bucket Contains more than just logs, views and performance, can get code coverage, results xml, full log 

Firebase testlab - Running tests 

Firebase - device options gcloud firebase test android models list 

Firebase console - command line Type - robo, instrumentation, game-loop gcloud firebase test android run --type instrumentation --app app/build/outputs/apk/debug/app-debug.apk --test app/build/outputs/apk/androidTest/debug/app-debug-androidTest.apk --devices-ids Nexus5 --os-version-ids 23 --locales en --orientations portrait --environment-variables coverage=true,coverageFile="/sdcard/coverage.ec" 

Firebase testlab - Artifacts and fetching 

Firebase - gcloud options Firebase test artifacts stores in Google cloud buckets Install gsutil to get CLI to interact with bucket artifacts gsutil ls gs://testingplaygroundresults 

Coverage reports Enable device storage in manifest --directories-to-pull /sdcard gsutil cp gs://testingplaygroundresults/*/*/artifacts/ coverage.ec .

Test sharing through flank 

Flank - Walmart Labs Scaling automated UI tests - Espresso and Appium Throttling support Device config Test results downloaded to project root 

Flank - Walmart Labs Test 1 Test 2 Test 3 Test 4 Test 5 Stores test times during first run Uses test times to distribute tests across devices https://github.com/TestArmada/flank
