Amazing Google I/O 2015. I'm very happy to see that developers are excited about testing on Android. The feedback was very clear: build is slow, testing on an array of devices is hard, the testing efforts have helped a lot, we need to talk about architecture, we need bigger samples and we need bigger venues for testing talks.

Our testing codelab was a major hit:

Talking to +Iberia Líneas Aéreas:
 - ...apart from your check-in system being almost completely broken, the page where you buy extra luggage doesn't work.
 - We recommend that if you're using Google Chrome or Safari, you try another browser.
 - ... you realize you're wasting money talking to angry customers like me because your intern did a bad job?
 - Yeah haha.

Last week we published a small but important sample for Espresso Intents on GitHub. It shows you how to fake an ActivityResult to keep your test hermetic, stubbing an Intent and simulating that a picture is fetched from the camera without leaving the main app.

We prefer short, focused UI tests to long end-to-end or flow tests. Espresso Intents lets you stay in your Activity and focus on your code. 

Take a look:

Ladies and Gentlemen, it's time to start your engines and do a git pull on our Android testing samples repository[0]!

We updated all the samples to use Runner/Rules 0.3, Espresso 2.2 and the new @VisibleForTesting annotation from support-annotations[1].

Your shiny new dependency configuration should look like this:

dependencies {
    compile 'com.android.support:support-annotations:22.2.0'
    androidTestCompile 'com.android.support.test:runner:0.3'
    androidTestCompile 'com.android.support.test:rules:0.3'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2'
}

Any chance you can share your slide deck? I was really keen to see your talk (but didn't manage to get a ticket in the lottery)

The crazy thrust vector control, the helpless RCS thruster giving up at the end, the incredible explosion... I for one am happy this didn't succeed.

Debugging and testing in Android Studio is now a lot easier thanks to recent enhancements in the IDE and our Gradle plugin, as well as the release of the Android Testing Support Library. Take a quick tour of new features with this Android Studio DevByte from +Wojtek Kaliciński

Here are my slides from my session at +Droidcon Spain where I talked about the new Unit testing support and the new Android Testing Support Library, with JUnit4 and Espresso-Intents:

http://goo.gl/Jwwroz

After the talk we discussed:
 - Testing Wear projects: Unit testing OK, Espresso OK but running Wear apps on "big" Android is weird. Explore it, file bugs!
 - We provide simple samples but we should also show how to combine different testing methodologies and publish bigger apps. Yes! And we should explore testing complex architectures and using popular frameworks.  
 - Code coverage 1: Make Java programs first and integrate with Android later. Cover that Java program with unit tests. UI test coverage makes no sense to me (as a metric). 
 - Code coverage 2: The JaCoCo workaround I've used is in https://code.google.com/p/android/issues/detail?id=144664  - What to test using Espresso: One good approach is to test the behavior of your activities isolated from the rest of the app and the network. Then create a small set of end-to-end tests that exercise long user flows with network access but expect these to be flaky.
