Should we maybe also pin the version of hypothesis we're installing in CI here? https://github.com/python/cpython/blob/main/.github/workflows/build.yml#L434

It seems fairly likely that Hypothesis could add other health checks in the future that would cause our CI to randomly start failing. And it's just generally good practice to pin test dependencies as well, so that we can easily reproduce errors that are happening in CI.

@dependabot and @sobolevn will bump hypothesis from time to time 👍

[AlexWaygood]

Maybe requirements-hypothesis.txt? Tools/requirements-tests.txt feels too similar to the existing Tools/requirements-dev.txt file we already have (and I think it's unlikely we'd use the same file for test dependencies that aren't related to the Hypothesis CI job).

I'm not even sure the file belongs in the Tools/ directory... maybe it should just be a top-level file?

[sobolevn]

Dependabot already knows about this dir and Hypothesis is clearly a tool :)
So, let's leave it there.

We could move them all into some other directory later, maybe .github/dependabot/, but let's get the CI back to green first.

[AlexWaygood]

yeah, Tools/ still doesn't feel ideal to me, but I don't feel strongly about where they should go 👍

[AlexWaygood]

LGTM, thanks! Will wait a little bit in case Hugo/Zac/Ezio want to chime in, though :)

I'm a big fan of pinning your transitive dependencies too with e.g. the pip-tools package, so long as they're updated regularly - hypothesis itself has an automated weekly PR for that.

We most recently added a new health check in January 2021, but I'd pin anyway. For example, a while ago Astropy's CI started failing because a new Hypothesis release was better at finding numerical bugs, and while you do want to find out about them (updates) you don't want them to break everyone's regression tests (pins). See also this blog post.

[sobolevn]

Two transitive deps that are installed in CI are: attrs and sortedcontainers. I think we can skip pinning them (the first regression here can prove me wrong).

Thanks for your help 👍
