Android Tests Exception In Constructor Noclassdeffounderror

After solving my issues with project structure and android tests it appears that another issue is coming, when I try to run my tests i get this exception: junit.framework.Assertion

Solution 1:

Following this post junit.framework.AssertionFailedError: Exception in constructor: (java.lang.NoClassDefFoundError) I tried adding the contrib lib with excludes like this:

dependencies {
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.0'
    androidTestCompile 'com.android.support.test:testing-support-lib:0.1'
    androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.0') {
        exclude group: 'com.android.support', module: 'appcompat'
        exclude group: 'com.android.support', module: 'support-v4'
        exclude module: 'recyclerview-v7'
    }
}

and also, moved all test classes to *.app.test package, set

testApplicationId "es.unizar.vv.mobile.catmdedit.app.test"

and now it properly works!
