Partial fix for upcoming testthat release

[hadley]

expect_success() and expect_failure() now test that you have exactly one success/failure and zero failures/successes. I can't quite figure out why the tests are still failing here; maybe it's something to do with recycling? I'm happy to help but I unfortunately I don't know enough about the lintr internals to figure out what's going wrong here.

We're planning to submit testthat to CRAN on Nov 10.

Thanks @hadley! Can I check if this is back-compatible? We have testthat (>= 3.2.1),, I just confirmed it works on 3.2.3 at least

NVM, confirmed succeed() and fail() are present in 3.2.1:

AFAICT you were only failing the {lintr} check, the main thing was by switching from Map() to a nested for loop it increased the cyclomatic complexity of the implementation enough to trigger a lint. I refactored the nested loops into a helper instead. Bonus -- we could drop the itr_env (replacing older <<- usage) in the new approach which I also find cleaner.

Thanks for the proactive fix! Your release time is perfectly fine. We are overdue for a release anyway.
