Re: Is test case with 700k lines of code a valid test case?


I don't speak with any community authority - I think your test tool is
misconfigured then. I don't see any pragmatic reason to generate such
a test. It's unlikely to mirror any real world code and artificial
test cases like this, at best only serve as some arbitrary data point.
