raised as issue

I love mixed language variable names with Umlauten :D

In the pre-defined test cases the $actual and $expected are reversed.
The definition is assertEquals(mixed $expected, mixed $actual).
This can be confusing in the error messages because the it shows the actual as the expected and vice versa.

Really?

I'm kidding...
actually, this is a onliner formated with spaces and new lines to improve readability ^^

You could easily remove some spaces and write it in one line 😁
