This function is exposed and kept alive for the oejskit plugin which is
abandoned and no longer works with recent plugins, so let's prepare to
completely remove it.
Mostly I wanted to get rid of mentions of "MarkItem" which is something
that no longer exists, but I improved a little beyond that and annotated
some simple types.
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.
The dynamic scope feature added in 10bf6aac76
necessitated some wrangling of arguments in pytest.fixture(). In
particular, it deprecated positional arguments in favor of keyword-only
arguments, while keeping backward compatibility.
The way it did this avoided some code duplication but ended up being
quite hard to follow and to annotate with types.
Replace it with some straightforward code, which is not very DRY but is
simple and easy to remove when the time comes.
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.
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.
