It was surprising that `tryfirst=True` would not result in lines being
added to the beginning with `pytest_report_header`.
This is due to lines being reversed, and therefore the same applies to
`pytest_report_collectionfinish`.
TestDurations tests the `--durations=N` functionality which reports N
slowest tests, with durations <= 0.005s not shown by default.
The test relies on real time.sleep() (in addition to the code which uses
time.perf_counter()) which makes it flaky and inconsistent between
platforms.
Instead of trying to tweak it more, make it use fake time instead. The
way it is done is a little hacky but seems to work.
This hook has some functionality to provide explicit markup for the test
status. It seemed unused and wasn't tested, so I was tempted to remove
it, but I found that the pytest-rerunfailures plugin uses it, so
document it and add a test instead.
Use `testdir.syspathinsert()` with multiprocessing tests:
- test_chained_exceptions_no_reprcrash
- test_exception_handling_no_traceback
This only works currently because `_importtestmodule` changes `sys.path`
as a side-effect.
It appears to be only required on Windows though - likely due to the
multiprocessing method used there.

This changes the link anchors in "reference.html", from e.g.
`reference.html#pytest-current-test` to
`reference.html#envvar-PYTEST_CURRENT_TEST`, but I think that is OK, and
not worth adding labels for the old anchors.
twisted started to use `attr.s(eq)` argument which was added recently,
so it fails with oldattrs. One of the CI jobs ran twisted and oldattrs
together, so it started to fail.
Move the twisted code to be covered by another job, and remove it from
the job with the oldattrs.
Previously, writing to sys.stdout/stderr in text-mode (e.g.
`print('foo')`) while a `capsysbinary` fixture is active, would crash
with:
/usr/lib/python3.7/contextlib.py:119: in __exit__
next(self.gen)
E TypeError: write() argument must be str, not bytes
This is due to some confusion in the types. The relevant functions are
`snap()` and `writeorg()`. The function `snap()` returns what was
captured, and the return type should be `bytes` for the binary captures
and `str` for the regular ones. The `snap()` return value is eventually
passed to `writeorg()` to be written to the original file, so it's input
type should correspond to `snap()`. But this was incorrect for
`SysCaptureBinary`, which handled it like `str`.
To fix this, be explicit in the `snap()` and `writeorg()`
implementations, also of the other Capture types.
We can't add type annotations yet, because the current inheritance
scheme breaks Liskov Substitution and mypy would complain. To be
refactored later.
