Difference between ActivityUnitTestCase and ActivityInstrumentationTestCase2

Question

I am new to Android Instrumentation cases. i have been looking at the API samples and see that sometimes we use ActivityUnitTestCase and the ActivityInstrumentationTestCase2. What is the difference between the two ? When would we use one over the other ?

Answer 1

See the difference discussed here: http://www.vogella.com/articles/AndroidTesting/article.html#activity_testing

Key points:

• ActivityUnitTestCase can be used for testing layout and isolated methods.
• ActivityInstrumentationTestCase2 can be used when you want to send touch/mouse events and to test state management.

Answer 2

ActivityInstrumentationTestCase2 class used for functional testing and ActivityUnitTestCase used for Unit testing an Activity.
