UNIT TESTING sábado, 30 de noviembre de 13 

What is it? A unit test is an automated piece of code that invokes a unit of work in the system and then checks a single assumption about the behavior of that unit of work. - The art of unit testing What are we going to test in Android? Business Logic View validation Behavior sábado, 30 de noviembre de 13 

Business Logic ‣Better if you make it independent from the Android platform ‣Possible to test using JUnit3 ‣Example sábado, 30 de noviembre de 13 

View validation ‣Mainly check the view elements are correctly displayed View Behavior ‣Check that the view behavior is the expected ¿EXAMPLES?? sábado, 30 de noviembre de 13 

Test What type of test should i use? Use only the JVM Use Android FW LET’S TRY WITH JUNIT alone... sábado, 30 de noviembre de 13

Robolectric to the rescue! sábado, 30 de noviembre de 13 

What is Robolectric? Robolectric is a unit test framework that de-fangs the Android SDK jar so you can test- drive the development of your Android app ‣Rewrite the Android SDK classes to be able to load in the JVM ‣Can use resources, themes, etc ‣Use Shadow Objects a.k.a Proxies: 1. Intercept of loading Android SUT 2. Rewrite the body 3. Bind “shadow object” to the new Android object ‣ Is possible to build your own shadow objects sábado, 30 de noviembre de 13

DAGGER ‣No reflection ‣Lazy ‣Module overrides sábado, 30 de noviembre de 13 

INTEGRATION TESTS sábado, 30 de noviembre de 13 

ActivityInstrumentationTestCase2 ‣Most basic integration test ‣Implements instrumentation to control ‣RunOnUIThread ‣Small, Medium and Large tests ‣Specific tests for Provider and Services sábado, 30 de noviembre de 13 

TYPE OF TESTS Running all small tests: adb shell am instrument -w - e size small com.android.foo/ android.test.InstrumentationTestRunner Running all medium tests: adb shell am instrument - w -e size medium com.android.foo/ android.test.InstrumentationTestRunner Running all large tests: adb shell am instrument -w - e size large com.android.foo/ android.test.InstrumentationTestRunner Source: http://googletesting.blogspot.com.es/2010/12/test-sizes.html sábado, 30 de noviembre de 13
