About me 

Firebase Quality Products ● Robo Tests ● Analysis Report ● Action Report ● Crash Reports ● Stack traces ● Tracking with logs ● Performance Monitoring ● Performance Tracing Test Lab Crashlytics Performance 

Firebase Test Lab 

Firebase Test Lab ● Allows us to run Robo Tests (No Espresso Tests Required) ● Supports APKs and AAB’s ● Can Run UI (Espresso) Tests as daily checks. ● Allows us to test on Real and Virtual Devices. ● Gives us comprehensive reports. ● Provides Screenshots and Crawling Graph ● Performance Results of the app ● Video records the full test ● Has Cloud function functionality 

exports.handleTestMatrixCompletion = functions.testLab. testMatrix().onComplete(testMatrix => { switch (testMatrix.state) { case 'FINISHED': console.log(`Test Lab Outcome${testMatrix.outcomeSummary}`); //SUCCESS: //FAILURE: //INCONCLUSIVE: //SKIPPED: break; default: console.log(`Completed with state ${testMatrix.state}`); } return null; }); Firebase Test Lab Cloud Function 

Firebase Crashlytics 

// Add dependency for Android implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1' # Pods for iOS pod 'Fabric', '~> 1.10.2' pod 'Crashlytics', '~> 3.13.4' Firebase Crashlytics 

Firebase Crashlytics 

Demo Crashlytics 

Firebase Crashlytics ● Automatic Crash reporting ● Checks if bugs have regressed or are new. ● Cloud function triggers to help with integrations. ● Custom Keys help us trace our steps. ● Analytics are also shown in the Log report. ● Reports information about device that app is crashing on. ● Velocity Alerts help us with recurring issues affecting users in almost real time. ● Can check crashes for unique users with userIndentifier method. 

Firebase Crashlytics: Custom keys Crashlytics.setString(key, "foo" /* string value */) Crashlytics.setBool(key, true /* boolean value */) Crashlytics.setDouble(key, 1.0 /* double value */) Crashlytics.setFloat(key, 1.0f /* float value */) Crashlytics.setInt(key, 1 /* int value */) 

exports.sendOnNewIssue = functions.crashlytics.issue(). onNew(async (issue) => { }); exports.sendOnRegressedIssue = functions.crashlytics.issue(). onRegressed(async (issue) => { }); exports.sendOnVelocityAlert = functions.crashlytics.issue() .onVelocityAlert(async (issue) => { }); Firebase Crashlytics Cloud Function 3 Firebase triggers Crashlytics triggers: 

Firebase Crashlytics Integration function createJiraIssue(summary, description, priority) { const project_url = functions.config().jira.project_url; const user = functions.config().jira.user; const pass = functions.config().jira.pass; const issue_type = functions.config().jira.issue_type; const component_id = functions.config().jira.component_id; ... };

Demo Firebase Performance 

Firebase Performance ● Automatic performance reporting ● HTTP Performance tracking Metrics ● Custom Performance Traces 

Firebase Performance: Custom Traces import com.google.firebase.perf.FirebasePerformance; import com.google.firebase.perf.metrics.Trace; val myTrace = FirebasePerformance.getInstance().newTrace("test_trace") myTrace.start() cache.fetch()?.let { myTrace.incrementMetric("item_cache_hit", 1) } ?: run { myTrace.incrementMetric("item_cache_miss", 1) } myTrace.stop() val metric = FirebasePerformance.getInstance(). newHttpMetric(...,FirebasePerformance.HttpMethod.GET)
