Deleted unit test, is still executed

The error I got is a bit of a weird one, but really annoying. I'm working on an Android application and I'm creating it in AndroidStudio 1.2.2.

I have created a class with some Unit Tests. But I noticed that's something was wrong so I corrected it. But the changes weren't used the next time I executed the unit-tests. I still get the output of those first unit-tests.

At this point,I've deleted the file, but even when the file is deleted, I still get the same message from those Unit-tests.

Anyone know how I can solve this?

thanks in advance
