+# CSIT Testcase naming convention rules.
+# https://wiki.fd.io/view/CSIT/csit-test-naming
+# Rules are defined as regular expressions in ordered array and checked in order
+# in a loop, where every iteration is catenated with previous rules. This way we
+# can detect where exactly the naming does not meet criteria and print error
+# from rule string array. This imply that rules are defined in a way of a single
+# string. First rule must start with ^ and last is terminated by $.
+# Rules are written from Left to Right.
+# Bash regular expression logic is used. Once the error is raised the checker is
+# breaked for current Testcase marking the expected fail.
+# One caveat of this solution is that we cannot proceed to check full names now
+# as majority of Testcases does not meet naming criteria.
