We use [`.class.getSimpleName()` extensively](https://github.com/Catrobat/Catroid/search?utf8=%E2%9C%93&q=class.getSimpleName%28%29) because in case we ever decide to rename the class, your IDE will pick up the change and the test case will continue to work, whereas with a hardcoded string you could miss it.

Another point is that changing it in one out of 164 places introduces inconsistency in the code base.

(That being said, IntelliJ/Android Studio's *Refactor &rarr; Rename…* functionality is pretty good and will probably pick up hardcoded strings and even comments.)
