DevFest Atlanta - Firebase Remote Config + Firebase Test Lab

Transcript

1. Firebase Remote Config & Test Lab Rebecca Franks Google Developer Expert - Android @riggaroo riggaroo.co.za
2. Who am I?
4. Firebase Product Offering
5. Firebase Dev Summit 2016 - Berlin • New Analytics Features - StreamView / DebugView • Crash Reporting is now out of Beta with new features • Udacity Course - Firebase in a weekend • Lots of other small things
6. Agenda • Remote Config • Setup & Basic Usage • Conditions • A/B Testing • Staged Rollouts • Custom Analytics Audiences • Test Lab • Robo Tests • Instrumentation Tests
7. Remote Config
8. • Key / Value Pairs saved on Firebase server • Change behaviour at runtime • No app update required Remote Config
9. Features • Quickly deploy changes • Customise your app for segments of user base • Run A/B Tests • Free!
10. Available for Android iOS
11. Firebase Server Setup
12. Android Setup Project Level build.gradle: buildscript { // ... dependencies { // ... classpath 'com.google.gms:google-services:3.0.0' } }
13. Android Setup App Level app/build.gradle: dependencies { // ... compile 'com.google.firebase:firebase-core:9.8.0' compile 'com.google.firebase:firebase-config:9.8.0' } // At the bottom apply plugin: 'com.google.gms.google-services'
14. Android Setup • Download google-services.json • Place in app/ folder. • Create remote config defaults file - res/xml/ remote_config.xml <?xml version="1.0" encoding="utf-8"?> <defaultsMap> <entry> <key>welcome_message</key> <value>Hello User!</value> </entry> </defaultsMap>
15. Initialise Firebase Remote Config remoteConfig = FirebaseRemoteConfig.getInstance(); FirebaseRemoteConfigSettings config = new FirebaseRemoteConfigSettings.Builder() .setDeveloperModeEnabled(BuildConfig.DEBUG) .build(); remoteConfig.setConfigSettings(config); remoteConfig.setDefaults(R.xml.remote_config);
16. Fetch remoteConfig.fetch(CACHE_TIME_SECONDS).addOnComplete Listener(new OnCompleteListener<Void>() { }); @Override public void onComplete(@NonNull Task<Void> task) { if (task.isSuccessful()) { Log.d(TAG, "Fetch Succeeded"); remoteConfig.activateFetched(); } else { Log.d(TAG, "Fetch Failed"); } displayWelcomeMessage(); }
17. Display void displayWelcomeMessage(){ String helloMessage = remoteConfig.getString("welcome_message"); greetingTextView.setText(helloMessage); }
18. Demo Android app fetching single remote config value
19. Types you can store on Remote Config • Strings • Integers • Booleans • Long • Double • Byte Arrays
20. Conditions • Powerful decision- making server • Target a group of app instances • Made up of one or more rules that must evaluate to true
21. Different greeting per platform?
22. Demo - No code changes!
23. Types of Conditionals • OS Type • App ID • Device in Region or Country • App Version • Language • Audience from Analytics • Random Percentile
24. How does the app decide what value to use? In-app default value? Static initialised value No No Yes Yes Parameter value Value fetched from the server?
25. Priority of Conditionals
26. A/B Testing & Feature Rollout • Experimenting with your UI • Different audiences receive different UI
27. A/B Testing - Server Setup
28. A/B Testing - Android Setup String experiment = config.getString("experiment_variant"); FirebaseAnalytics.getInstance(this) .setUserProperty("Experiment", experiment); if (experiment.equals("variant_a")) { //.. } else if (experiment.equals("variant_b")) { //... } else { //.. }
29. Demo A B No Experiment
30. Analytics Log your events + track in the Firebase Console buttonCheckout.setOnClickListener(new View.OnClickListener() { @Override public void onClick(final View view) { //.. } }); firebaseAnalytics.logEvent(“CheckoutClicked”, new Bundle());
31. A/B Testing - Analytics
32. Filter - Variant_A
33. OR Export to BigQuery
34. Experiment A - Winner! A
35. Gradual Feature Rollouts • Leverage “User in Random Percentile” feature • Gradually increase the value of the percentage • Rollout to more customers as you gain confidence
36. Create stage rollout condition
37. Create config using that condition
38. Gradually increase value
39. Custom Audiences - Events
40. Remote Config using Custom Audience
41. Unsupported App Versions
42. Unsupported App Versions
43. Unsupported App Versions void loadAppSupported() { boolean appSupported = remoteConfig.getBoolean("app_supported"); if (!appSupported) { showAppNotSupportedDialog(); } }
44. Test Lab
45. What is Firebase Test Lab? • Run tests at Googles Device Farm • Virtual Devices + Physical Devices • Robo Tests & Custom Instrumentation Tests • Free Tier • 5 tests per day on physical devices • 10 tests per day on virtual devices • Pay per hour
46. Runs on Android
47. Why run tests on Firebase? • History of results • Logs attached to each test • Screenshots & videos • Don’t have to manage your own device farm
48. Robo Test • Random clicking around in your application + recording results • No code changes required to run a Robo Test • Uses Monkey Runner
49. Running Monkey Locally $ adb shell monkey -p your.package.name -v 500 Command line:
50. Running Monkey on Firebase
51. Viewing Robo Test Results
52. Instrumentation Tests • Need to be writing test code • Espresso • Robotium • UIAutomator
53. Run Instrumentation Tests Locally • Device / Emulator attached • Espresso: ./gradlew connectedAndroidTest
54. Options for running tests • Firebase Console • Command Line - Using gcloud API • Android Studio
55. Running Instrumentation Tests in Android Studio
56. Viewing Test Results
57. Recap •Remote Config •Getting setup •Using remote config •A/B Testing + Gradual Roll outs •Test Lab •Robo Tests •Instrumentation tests
