与Robotium进行junit测试时出现AssertionFailedError

Question

I keep getting the following exception on every test and I can't figure out why. Hoping someone has some insight.

 ----- begin exception -----

Answer 1

You have write the correct name of the Activity you want to go back to. I think the name of your activity is MainActivity and not mainActivity.
