@jennybc could you please interactively kick the tires of this PR with https://github.com/hadley/testcoverage and convince yourself that it all works as expected?
Yes, I feel like my tire-kicking of https://github.com/hadley/testcoverage has been successful.
But as I've used test_coverage_active_file()
, which apparently I don't do much of in real life, I see this warning, which is coming from covr, I think. I suppose this is a side observation, as I don't think it has anything to do with recent changes in testthat or in this PR.
> test_coverage_active_file()
Warning message:
In mapply(FUN = f, ..., SIMPLIFY = FALSE) :
longer argument not a multiple of length of shorter
I made some other updates on main
to eliminate some nuisance noise in R CMD check
, so I merged that in here.
🥳
Do you have a reprex for the recycling warning? I know I saw it multiple times in the workshop, but now I don't.
I am also not seeing the mapply()
warning any more 😐
This was never used correctly because we're passing the path to the package root, instead of the test directory. Additionally, based on https://github.com/hadley/testcoverage, they don't actually appear to be needed.
Fixes r-lib/testthat#1858
@jennybc my main scepticism here for the case of
test_coverage_active_file()
, I can't see how this can possibly work (even though it does). As far as I can tell, nothing intest_coverage_active_file()
causes eitherTESTTHAT_PKG
or the edition to be set correctly, but the tests still pass....
Ooooh maybe the problem is that
test_coverage_active_file()
never actually reveals when the test fails....
Yes, that was the problem, and once I fixed that, it revealed that the snapshot paths weren't set up correctly, and it helped me understand why
local_test_directory()
is needed here, and why it works. I've added comments so hopefully this is less of a journey in the future.
