  1. Ensure that STDERR is empty during connect_ok

    Daniel Gustafsson <daniel@yesql.se> — 2022-02-02T14:40:39Z

    As part of the NSS patchset, quite a few bugs (and NSS quirks) were found by
inspecting STDERR in connect_ok and require it to be empty.  This is not really
NSS specific, and could help find issues in other libraries as well so I
propose to apply it regardless of the fate of the NSS patchset.

(The change in the SCRAM tests stems from this now making all testruns have the
same number of tests.  While I prefer to not plan at all and instead run
done_testing(), doing that consistently is for another patch, keeping this with
the remainder of the suites.)

Since commit 405f32fc4960 we can rely on subtests for this, so perhaps
we should group all the tests in connect_ok() (including your new one)
into a subtest; then each connect_ok() calls count as a single test, and
we can add more tests in it without having to change the callers.

+1

+1 to that too, counting the tests is a pretty useless exercise.

Disclaimer: longer term I would prefer to remove test plan counting like above
and Toms comment downthread.  This is just to make this patch more palatable on
the way there.

Making this a subtest in order to not having to change the callers, turns the
patch into the attached.  For this we must group the new test with one already
existing test, if we group more into it (which would make more sense) then we
need to change callers as that reduce the testcount across the tree.

This makes the patch smaller, but not more readable IMO (given that we can't
make it fully use subtests), so my preference is still the v1 patch.

Or did I misunderstand you?

Well, it wasn't my intention that this patch would not have to change
the callers.  What I was thinking about is making connect_ok() have a
subtest for *all* the tests it contains (and changing the callers to
match), so that *in the future* we can add more tests there without
having to change the callers *again*.

I think you did.

Rather than waiting for Someone™ to find a suitably-shaped tuit to do a
whole sweep converting everything to done_testing(), I think we should
make a habit of converting individual scripts whenever a change breaks
the count.

Or when anyone edits a script, even if the number of tests doesn't get
broken.

+1.

Sure, if the committer is up to doing it, but let's not make that a hard
requirement for any commit that touches a test script.

Sounds sensible from here.  Thanks!

All the code paths seem to be covered, at quick glance.

Applied, minus the changes to the test plans which are no longer required after
549ec201d6.
