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.
Allows for filtering of PytestCacheWarning.
Using `_issue_warning_captured` is not necessary here, and was probably
only used because the cacheprovider misses warnings during
`pytest_sessionfinish`, which is also fixed here.
I think the usage of `_issue_warning_captured` can be removed/reduced
further, but also that this is good enough for now.

* Use code highlighting if pygments is installed
* Use colorama constants instead of bare ascii codes
Could not find the exact equivalent of 'hl-reset' code using colorama
constants though.
* Refactor ASCII color handling into a fixture
* Revert back to using explicit color codes
* In Python 3.5 skip rest of tests that require ordered markup in colored output
Use suggestion in review and use a subplugin so hooks will only be active
if we enable faulthandler ourselves.
Fix#6575

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`.
The convention is "assert result is expected". Pytest's error diffs now
reflect this. "-" means that sth. expected is missing in the result and
"+" means that there are unexpected extras in the result.

This started by looking at how to get the current test item in general,
and then I noticed that it is not necessary for the capture plugin to
track it manually in the first place.
Previously this would be turned via `py.path.local("")` into the current
working directory.
This appears to be what `fspath = fn and py.path.local(fn) or None`
tries to avoid in `getfslineno`'s `TypeError` handling already, if
`Code` would raise it.
Plugins specified with ``-p`` are now loaded after internal plugins, which
results in their hooks being called *before* the internal ones.
This makes the ``-p`` behavior consistent with ``PYTEST_PLUGINS``.
* fix/adjust test_disable_plugin_autoload
* adjust test_plugin_loading_order
Reverts https://github.com/pytest-dev/pytest/pull/6610.
The tested `getfslineno` is `src/_pytest/_code/source.py` actually,
exported via `src/_pytest/_code/__init__.py`.
I've confused it with the one in `src/_pytest/compat.py` apparently.
It should be in `test_code` when testing `_pytest._code.getfslineno`,
not to be confused with `_pytest._code.source.getfslineno`.
Adds an extra assert (via https://github.com/pytest-dev/pytest/pull/6590).
- 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.
Previously, _initialparts was a list whose first item was a
`py.path.local` and the rest were `str`s. This is not something that
mypy is capable of modeling. The type `List[Union[str, py.path.local]]`
is too broad and would require asserts for every access.
Instead, make each item a `Tuple[py.path.local, List[str]]`. This way
the structure is clear and the types are accurate.
To make sure any users who might have been accessing this (private)
field will not break silently, change the name to _initial_parts.
Make EncodedFile, used for captured output streams, method .write return
the number of characters written. Add test for captured stderr write.
Fixes#6557.

Without restoring the cwd, successive tests might fail to parse the
config (via `_pytest.config._prepareconfig()`, for when `--lsof` is
used).
And it is good practice to restore the cwd in any case anyway.
These are more "dirty" than the previous batch (that's why they were
left out). The trouble is that `compile` can return either a code object
or an AST depending on a flag, so we need to add an overload to make the
common case Union free. But it's still worthwhile.
Somehow in Python 3.5 on Windows this test fails with:
File "c:\hostedtoolcache\windows\python\3.5.4\x64\Lib\multiprocessing\connection.py", line 302, in _recv_bytes
overlapped=True)
OSError: [WinError 6] The handle is invalid
This only happens in this platform and Python version, decided to use
a dummy traceback as originally done in #6412.

Fix#5971
This fixes some type: ignores due to typeshed update.
Newer mypy seem to ignore unannotated functions better, so add a few
minor annotations so that existing correct type:ignores make sense.
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".
Sets `PY_COLORS=0` in the environment by default, which is used by pylib.

This feature was added in commit
007a77c2ba, but was never used in pytest
itself. A GitHub code search doesn't find any users either (only pytest
repo copies). It seems safe to clean up.
The previous test was better in that it used fakes to test all of the
real code paths. The problem with that is that it makes it impossible to
simplify the code with `isinstance` checks. So let's just simulate the
issue directly with a monkeypatch.
It currently fails with a TypeError, and was not updated since 2013 -
therefore it can be assumed that it is not important to support it.

This is a useful utility to abstract the caching property idiom.
It is in compat.py since eventually it will be replaced by
functools.cached_property.
Fixes#6131.
It is a little too obscure IMO, but the reason I want to drop it is that
type checking has no hope of understanding such dynamic constructs.
The warning argument wasn't used.
This fixes/removes the previous hack of re-trying with minimum width,
which fails short when it splits strings.
This inherits from `pprint.PrettyPrinter` to override `_format` in a
minimal way to always dispatch, regardless of the given width.

This causes INTERNALERRORs with pytest-django, which uses
`pytest.fail` (derived from `BaseException`) to prevent DB access, when
pytest then tries to e.g. display the `repr()` for a Django `QuerySet`
etc.
