Ran Benita 4d813fdf5e recwarn: improve return type annotation of non-contextmanager pytest.warns 
It returns the return value of the function.
 2020-06-25 14:30:42 +03:00
Ran Benita 24dcc76495 Use a hack to make typing of pytest.fail.Exception & co work 
Mypy currently is unable to handle assigning attributes on function:
https://github.com/python/mypy/issues/2087.
pytest uses this for the outcome exceptions -- `pytest.fail.Exception`,
`pytest.exit.Exception` etc, and this is the canonical name by which they
are referred.

Initially we started working around this with type: ignores, and later
by switching e.g. `pytest.fail.Exception` with the direct exception
`Failed`. But this causes a lot of churn and is not as nice. And I also
found that some code relies on it, in skipping.py:

    def pytest_configure(config):
        if config.option.runxfail:
            # yay a hack
            import pytest

            old = pytest.xfail
            config._cleanup.append(lambda: setattr(pytest, "xfail", old))

            def nop(*args, **kwargs):
                pass

            nop.Exception = xfail.Exception
            setattr(pytest, "xfail", nop)
        ...

So it seems better to support it. Use a hack to make it work. The rest
of the commit rolls back all of the workarounds we added up to now.

`pytest.raises.Exception` also exists, but it's not used much so I kept
it as-is for now.

Hopefully in the future mypy supports this and this ugliness can be
removed.

Ran Benita 3d2680b31b Fix type of pytest.warns, and fix check_untyped_defs in test_recwarn 
The expected_warning is optional.

Ran Benita 866904ab80 Revert "Let context-managers for raises and warns handle unknown keyword arguments" 
This reverts commit dfe54cd82f.

The idea in the commit was to simplify the code by removing the check
and instead letting it TypeError which has the same effect.

However this type error is caught by mypy, and rather than ignoring the
error we think it's better and clearer to go back to the previous
explicit check.

Bruno Oliveira f1183c2422 Remove the 'issue' marker from test suite 
It doesn't seem to add much value (why would one execute tests
based on that marker?), plus using the docstring for that

Bruno Oliveira 90a8faabba Fix test for py37 
In previous Python versions, the list of warnigns appears like:

	... list of emitted warnings is: [UserWarning('user',)].

In Python 3.7 apparently the string representation has been improved to:

	... list of emitted warnings is: [UserWarning('user')].

"catch warnings" magic for us, simplifying the code a bit.
