- Isolate logic for getting expected exceptions
- Use original method name, as users see it when entering the debugger

Otherwise 'normal' failures won't call teardown explicitly

rename test_pdb to test_debugging

Release notes:
https://mypy-lang.blogspot.com/2019/11/mypy-0.html

Update mypy 0.740 -> 0.750

unittest: do not use TestCase.debug() with `--pdb`

Merge master into features

As discussed, sometimes we will need to introduce changes
which are not necessarily removals but might break existing
suites

…-breakage

Deprecation policy - insert considerations for breaking changes

Fix pytest-dev#4597

pytest-dev#4597: tee-stdio capture method

An improvement seems more adequate here.

Change 4639 from feature to improvement

…-matching-case-insensitive

Make keyword expression matching case-insensitive

As far as the output is concerned, they are both identical so it doesn't
make sense to have both.

setup, teardown, and collect failures are already reported as "errors", "E".

Passing in a tuple crashes in `_prepareconfig`:

Might be worth handling (converting it to a list for example), but it
was documented to be a list to begin with when removing support for
strings (a7e4016).

- Add list of fixtures to start of fixture chapter
- Add "fixture" cross ref type

…#6793)

Follow-up to 13f7f27.

Fixes pytest-dev#6752.

It should only return `True` when something is to be ignored, not
`False` otherwise typically.

This caused e.g. bad interaction with the cacheprovider (before
pytest-dev#6448).

Ref: pytest-dev#6671 (comment)

Originally added in a289142 (with `TestRootdir`), but then
accidentally moved to `TestOverrideIniArgs` in 802755c.

Last usage was removed in 22dc47d.
