added pattern test cases for all detectors starting with Alphabet a (…

…#3539)

* added pattern test cases

* some more test cases with some fixes too

* improved apimetrics regex and added test cases

* added more pattern test cases

* added more pattern test cases

* last brick of pattern test cases for a Alphabet
