* It also makes sure that the expected output does not change when run through the fixer. That means that you
* do not need two test cases like [$expected] and [$expected, $input] (where $expected is the same in both cases)
* as the latter covers both of them.
* This method throws an exception if $expected and $input are equal to prevent test cases that accidentally do
* not test anything.
