I agreed that  the using of Cleaner is still heavy, but it may be acceptable as the code is for testing only.   If a new static method is introduced, test cases using the current API would also need update so as to benefit from it.  I was hesitate for test cases update as it may involve more evaluations (and risks).  But let me check.
