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.
Fixes: #3333
From the description it seemed to me as if just prefixing your methods with ``test_`` was enough, but you also need to prefix your class with ``Test``. Of course, in the reference material this is clearly stated, but I think it makes sense to mention it here as well, since you also mention the part about the methods' prefix.
This allows for e.g. Jedi to infer types (it checks the name).
It was only used to support Python 3.5.0/3.5.1, where this is is not
available in the `typing` module.
Ref: https://github.com/davidhalter/jedi/issues/1472
Uses `TYPE_CHECKING = False` in `_pytest.outcomes` to avoid having to
work around circular import.
Both references were referencing links from Python because of our intersphinx
mapping in `conf.py`:
intersphinx_mapping = {"python": ("https://docs.python.org/3", None)}
Because Python's docs explicitly define both references, Sphinx fallbacks to
them instead of generating implicit references as was expected.
Fix#6397
I've updated the text and incorporated the topics from #5275, so this
can now be part of the official docs, and #5275 can be closed/unpinned.
Closes#5275
* Rearrange section about context manager to be in order
* Link to `pytest.warns` and `recwarn` since a reader going top to bottom won't have seen about those yet.
* Used only context manager form in the example; the call form is somewhat obsolete
and is mentioned in the reference docs already.
* Reuse the 'myfunction' from first example on the second one

The order of invocations 'python -m pytest' and 'pytest' are different in the header and the explanation. Me being lazy reading about the behaviour of 'former' looked up quickly the title and rushed to implementation to discover it actually works the other way - as stated in the documentation. So I propose to switch the order in the title to achieve consistent ordering and not confusing somebody like me again! :)
