Don't import `pytest` from within some `_pytest` modules since an
upcoming commit will import from them into `pytest`.
It would have been nice not to have to do it, so that internal plugins
look more like external plugins, but with the existing layout this seems
unavoidable.
Regressed in 6.1.0 in 62e249a1f9.
The `x` is an `str` but is expected to be a `pathlib.Path`. Not caught
by mypy because `config.getini()` returns `Any`.
Fix by just removing the `bestrelpath` call:
- testpaths are always relative to the rootdir, it thus would be very
unusual to specify an absolute path there.
- The code was wrong even before the regression: `py.path.local`'s
`bestrelpath` function expects a `py.path.local`, not an `str`. But it
had some weird `try ... except AttributeError` fallback which just
returns the argument, i.e. it was a no-op. So there is no behavior
change.
- It seems reasonable to me to just print the full path if that's what
the ini specifies.
This indicates at least for people using type checkers that these
classes are not designed for inheritance and we make no stability
guarantees regarding inheritance of them.
Currently this doesn't show up in the docs. Sphinx does actually support
`@final`, however it only works when imported directly from `typing`,
while we import from `_pytest.compat`.
In the future there might also be a `@sealed` decorator which would
cover some more cases.
This makes mypy raise an error whenever it detects code which is
statically unreachable, e.g.
x: int
if isinstance(x, str):
... # Statement is unreachable [unreachable]
This is really neat and finds quite a few logic and typing bugs.
Sometimes the code is intentionally unreachable in terms of types, e.g.
raising TypeError when a function is given an argument with a wrong
type. In these cases a `type: ignore[unreachable]` is needed, but I
think it's a nice code hint.
This prevents referring to a generic type without filling in its generic
type parameters.
The FixtureDef typing might need some more refining in the future.
We barely use it; the couple places that do are not really worth the
extra dependency, I think the code is clearer without it.
Also simplifies one (regular) itertools usage.
Also improves a check and an error message in `pytest.raises`.
`TerminalWriter`, imported recently from `py`, contains its own
incomplete wcwidth (`char_with`/`get_line_width`) implementation. The
`TerminalReporter` also needs this, but uses the external `wcwidth`
package.
This commit brings the `TerminalWriter` implementation up-to-par with
`wcwidth`, moves to implementation to a new file `_pytest._io.wcwidth`
which is used everywhere, and removes the dependency.
The differences compared to the `wcwidth` package are:
- Normalizes the string before counting.
- Uses Python's `unicodedata` instead of vendored Unicode tables. This
means the data corresponds to the Python's version Unicode version
instead of the `wcwidth`'s package version.
- Apply some optimizations.
_pytest.timing is an indirection to 'time' functions, which pytest production
code should use instead of 'time' directly.
'mock_timing' is a new fixture which then mocks those functions, allowing us
to write time-reliable tests which run instantly and are not flaky.
This was triggered by recent flaky junitxml tests on Windows related to timing
issues.
This is already done in pytest_runtest_logstart, so the fspath is
already guaranteed to have been printed (for xdist, it is disabled
anyway).
write_fspath_result is mildly expensive so it is worth avoiding calling
it twice.
Only filter with known failures, and explicitly keep paths of passed
arguments.
This also displays the "run-last-failure" status before collected files,
and does not update the cache with "--collect-only".
Fixes https://github.com/pytest-dev/pytest/issues/6968.
- replace "tests with warnings" with just warnings: they a) might not
come from a test in the first place, and b) a single test might have
multiple warnings.
- fix usage of (unused) argument to `collapsed_location_report`

Flushing on every write is somewhat expensive.
Rely on line buffering instead (if line buffering for stdout is
disabled, there must be some reason...), and add explicit flushes when
not outputting lines.
This is how regular `print()` e.g. work so should be familiar.
ExitCode is used in several internal modules and hooks and so with type
annotations added, needs to be imported a lot.
_pytest.main, being the entry point, generally sits at the top of the
import tree.
So, it's not great to have ExitCode defined in _pytest.main, because it
will cause a lot of import cycles once type annotations are added (in
fact there is already one, which this change removes).
Move it to _pytest.config instead.
_pytest.main still imports ExitCode, so importing from there still
works, although external users should really be importing from `pytest`.
Fix mypy errors:
src/_pytest/runner.py:36: error: "addoption" of "OptionGroup" does not return a value [func-returns-value]
src/_pytest/helpconfig.py:64: error: "addoption" of "OptionGroup" does not return a value [func-returns-value]
src/_pytest/terminal.py:67: error: "_addoption" of "OptionGroup" does not return a value [func-returns-value]
src/_pytest/terminal.py:75: error: "_addoption" of "OptionGroup" does not return a value [func-returns-value]
- refactor _get_main_color/build_summary_stats_line
- factor out property _is_last_item; test_summary_stats: tr._is_last_item
- _write_progress_information_filling_space: remove color arg
- use setter for stats, handling main color
- _get_main_color: skip cache for last item
- Handle random order in test for py35.
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".
indicate current outcome/status with color of percentage indicator
Fix type annotation, refactor _write_progress_information_filling_space
Keep code in _get_main_color as similar as possible to how it was before
Write test
Make black-compliant
Fix error in newly introduced test_collecterror
Make tests more readable by using constants and f-strings
Remove accidentally added monkeypatch
Make Python 3.5-compatible, add changelog entry
Add newline at the end of changelog file
`-ra` / `-rA` will include "w" also. This does not explicitly mention
it (allowing for change the behavior), but makes it a) clearer that "w"
is a recognized reportchar, and b) less confusing that `-ra
--disable-warnings` still displays them.
