So I've seen the changed testcase failing, rarely, in CI.
It's a bit of a curious testcase because so far as I can see it should only ever go through the branch that I've retained - as previously structured the output was quite unhelpful on failure (
venv.run()
gets called two times, instead of three, in the examples I recall).So I've rearranged that, and also included information from the original exception in the
PackageInfoError
which - I think - must be the one that is being hit. The hope being that next time the test fails, we'll get to see what the problem was.I speculate that this might be #7611 being hit in poetry's own CI pipelines all along.
However obviously now that I want the test script to fail, it is passing reliably, I've tried a few times and not hit problems...
Might just as well merge this though I think - it improves the clarity of the scripts anyway, and probably sooner or later it will pay off and reveal something.
