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

The same error occurred to me when I follow Google IOSched app and set up my project with three build types [debug,release,staging] where debug and release share the same source directory

sourceSets {
    debug.java.srcDir 'src/debugRelease/java'
    release.java.srcDir 'src/debugRelease/java'
}

In this case, specify the testBuildType in your module-level build.gradle file and the project should now be able to resolve symbol 'AndroidJUnit4'.

...
sourceSets {
    debug.java.srcDir 'src/debugRelease/java'
    release.java.srcDir 'src/debugRelease/java'
}

testBuildType "staging"
...
