Question

This is my first time setting up an Android test project to test a Android project.

I\'ve created a very basic test case which I\'m trying to get to run, however wh

Answer 1

I had this problem after a merge, in which build.gradle was specifying the wrong test package, since I had been using the default.

By simply removing these lines from build.gradle, it was able to find the necessary classes in the default package, which is src/androidTest.

sourceSets {
    instrumentTest.setRoot('src/instrumentTest')
}
//removed this to use the default androidTest source set.

This will probably not be the exact solution, but hopefully guides someone in the right direction.
