Anyone have a good idea of what to do to get GitHub - anykeyh/crystal-coverage: Coverage tool for Crystal lang updated and into a usable state? (Last commit to master was 2020-04-20, more than a year ago. I ran the non-standard specs and got no output. I didn’t dig much deeper into it.) Or, is there an alternative Code Coverage tool for Crystal?
My bad. I read the doc’s a bit more. But, still had issues, so I worked on updating via a PR of my old fork of the repo (forked off the
e781f8c on Apr 20, 2020 commit, which is the latest commit on the master branch of GitHub - anykeyh/crystal-coverage: Coverage tool for Crystal lang). PR at Drhuffman12/update for crystal 1 0 0 by drhuffman12 · Pull Request #1 · drhuffman12/crystal-coverage · GitHub is kinda working, but still has issues; maybe I didn’t fix enough of the code? I logged an issue here: Update repo for Crystal 1+ and document how to run the tests; maybe add an example shard that uses it · Issue #17 · anykeyh/crystal-coverage · GitHub.
It is not a whole coverage tool but it covers some stories there.
LLVM has llvm-cov, which I think might be a way to have coverage reports, but for that the compiler needs to emit some additional information (via some opt-in flag probably). This is not done neither has been attempted AFAIK.
I’m pretty sure one day something will happen that will allow us to write our own coverage tool in a much easier way ;-)
(no promises, though)
care to elaborate? that sounds very intriguing! even without the prospect of a promise
It’s a tool I’m working on which might enable code coverage and some other things. But I will reveal it in the upcoming Crystal Conference. So you’ll know then, or shortly afterwards. Sorry, I can’t reveal much more right now. Plus it’s not sure it will work!
@bcardiff , Thanks! I’ll check those out!
@asterite , I look forward to your announcement!
I’ll probably shelf my PR for now and see what you two have and come up with.
I know some dev teams have a minimum code coverage percentage policy for all PR merges into their codebases. So, having a working Code Coverage tool for Crystal could be another selling point for adoption of Crystal (or killing point while still missing).
