Hi there,
I have a more general problem namely I wrote a grammar and now I want
to test it, which means I need test cases so that every posibility of
the grammar is covered by one test case.
Example:
rule : "from" IDENT "select" (IDENT)?
for a complete coverage I need two test cases:
1. "from" abc "select"
2. "from" abc "select" def
Do you know an efficient approach getting all these test cases? How
about recursion regarding a rule like this: plus : IDENT ("+" plus)+ ?
Thanks a lot,
Uli
