Cleaning up some left-overs from #20347 and preparing the tests for changing the default of join to 'left' in 1.0 (which would break some tests that assume no alignment currently). As a side benefit, this has:

  • nicer parametrization
  • nicer switches (and reduced usage of them within the tests)
  • now follows result / expected pattern instead of calculating result within assert_..._equal

@h-vetinari : Anaconda servers are experiencing some 503 issues. I'll restart tests later.

why are you removing the join here? is it not needed? should these be parameterized by join type?

In the course of #20347, the warnings were originally always issues whenever join was not specified - and this test correspondingly adapted. However, the warnings were later reduced to only be emitted in case of different indexes between caller and others, so in this case, it's not necessary.

This module's full of exp (maybe even the majority), but I replaced it in the diff I'm working on now.

not sure what's up with these TestExcelWriter test failures...? rebasing didn't help.

Edit: saw that 22601 solved it. Rebased again.
