Fixed:
1. setInputStringsRegex(String aInputStringsRegex) -> 
setPrefixOrSuffixForClassName (String  aPrefixOrSuffixForClassName)
private static String getIdentTest(DetailAST aNodeWithIdent) ->
getIdent(DetailAST aNodeWithIdent)

2.
extendsClass(mCurrentClassNode, TestCase);
-->
isExtendsClass(mCurrentClassNode, TestCase);

3.
final String prefixOrSuffixForClassName = aPrefixOrSuffixForClassName ==
null ? : aInputStringsRegex;
mInputStringsRegex = Pattern.compile(prefixOrSuffixForClassName);
