Cannot resolve symbol 'AndroidJUnit4'

Question

Obviously I need the correct import statment to solve this problem. According to the docs for AndroidJUnit4, this should be

import android.support.test.runn         


        

Answer 1

Ok so here is your mistake and mine!

If we are going to write a pice of code for Local Unit Testing we shouldn't use @RunWith(AndroidJUnit4.class) cause we do not use AndroidJUnit4 but we need Junit4. so we should write @RunWith(JUnit4.class). And of course your java test file is under app/src/test/java/your.package.name directory.

Else if (!!) we want to write some Android Instrumented Unit Test we should put our test java files in app/src/androidTest/java/your.package.name directory and use annotation like @RunWith(AndroidJUnit4.class)
