Compiler wrapper
First, it reads the TTCN-3 files and extracts the expected messages.
These are regular expressions delimited by // and //
(because // is a comment in TTCN-3 and //xxx// looks somewhat like a sed/Perl/Javascript
regular expression: /xxx/).
Next, it runs the compiler and checks for the expected messages in the output.
