Test:
`warnings.warn()` expects that its first argument is a `str` or a
`Warning`, but since 9454fc38d3
`pytest.warns()` no longer allows `Warning` instances unless the first
argument the `Warning` was initialized with is a `str`. Furthermore, if
the `Warning` was created without arguments then `pytest.warns()` raises
an unexpected `IndexError`. The new tests reveal the problem.
Fix:
`pytest.warns()` now allows using `warnings.warn()` with a `Warning`
instance, as is required by Python, with one exception. If the warning
used is a `UserWarning` that was created by passing it arguments and the
first argument was not a `str` then `pytest.raises()` still considers
that an error. This is because if an invalid type was used in
`warnings.warn()` then Python creates a `UserWarning` anyways and it
becomes impossible for `pytest` to figure out if that was done
automatically or not.
[ran: rebased on previous commit]
- Previously, `getpass.getuser()` would leak an ImportError if the
USERNAME environment variable was not set on Windows because the `pwd`
module cannot be imported.
- Starting in Python 3.13.0a3, it only raises `OSError`.
Fixes#11874
* Fix handling empty values of NO_COLOR and FORCE_COLOR
Fix handling NO_COLOR and FORCE_COLOR environment variables to correctly
be ignored when they are set to an empty value, as defined
in the specification:
> Command-line software which adds ANSI color to its output by default
> should check for a NO_COLOR environment variable that, when present
> *and not an empty string* (regardless of its value), prevents
> the addition of ANSI color.
(emphasis mine, https://no-color.org/)
The same is true of FORCE_COLOR, https://force-color.org/.
* Streamline testing for FORCE_COLOR and NO_COLOR
Streamline the tests for FORCE_COLOR and NO_COLOR variables, and cover
all possible cases (unset, set to empty, set to "1"). Combine the two
assert functions into one taking boolean parameters. Mock file.isatty
in all circumstances to ensure that the environment variables take
precedence over the fallback value resulting from isatty check (or that
the fallback is actually used, in the case of both FORCE_COLOR
and NO_COLOR being unset).
Tests if a captured exception group contains an expected exception.
Will raise `AssertionError` if the wrapped exception is not an exception group.
Supports recursive search into nested exception groups.
Move handling of user_properties to `finalize()`.
Previously if a fixture failed during teardown, `pytest_runtest_logreport` would not be called with "teardown", resulting in the user properties not being saved on the JUnit XML file.
Fixes: #11367
Added handling of %f directive to print microseconds in log format options, such as log-date-format. It is impossible to do with a standard logging.Formatter because it uses time.strftime which doesn't know about milliseconds and %f. In this PR I added a custom Formatter which converts LogRecord to a datetime.datetime object and formats it with %f flag. This behaviour is enabled only if a microsecond flag is specified in a format string.
Also added a few tests to check the standard and changed behavior.
Closes#10991
Forces requested `caplog` logging levels to be enabled if they were disabled via `logging.disable()`
`[attr-defined]` mypy error ignored in `logging.py` because there were existing errors with the imports
and `loggin.Logger.manager` is an attr set at runtime. Since it's in the standard lib I can't really fix that.
Ignored an attr-defined error in `src/_pytest/config/__init__.py` because the re-export is necessary.
Fixes#8711
Closes#10831.
This fixes a small bug where running tests that contained
`pytest.fail(pytrace=False)` with the `--tb=line` flag set results in
an output of "None" in the Failures section of the output, and adds
a test to ensure the behavior is correct.
By "empty traceback" I mean a traceback all of whose entries have been
filtered/cut/pruned out.
Currently, if an empty traceback needs to be repr'ed, the last entry
before the filtering is used instead (added in
accd962c9f).
Showing a hidden frame is not so good IMO. This commit does the
following instead:
1. Shows details of the exception.
2. Shows a message about how the full trace can be seen.
Example:
```
_____________ test _____________
E ZeroDivisionError: division by zero
All traceback entries are hidden. Pass `--full-trace` to see hidden and internal frames.
```
Also handles `--tb=native`, though there the `--full-trace` bit is not
shown.
This commit contains some pieces from
431ec6d34e (which has been reverted).
Helps towards fixing issue # 1904.
