`deprecated_call` used to accept any warning. As of #897, it
is now specific to DeprecationWarnings, and another commit in
this PR extends this to PendingDeprecationWarnings. This commit
makes sure this stays the case.
`deprecated_call` now looks for PendingDeprecationWarnings,
as it did previously but was broken by #897. Fixes#1037.
Also added a test so this does not happen again.
Because the test relies that two subsequent tests try to use pytest.warns to capture
the exact same warning, it is better to use testdir to ensure test execution
occurs in the order we expect (which might be different with pytest-xdist or
pytest-random for example)
Works in a similar manner to `raises`, but for warnings instead
of exceptions. Also refactored `recwarn.py` so that all the
warning recording and checking use the same core code.
The only remaining 'py.test' references are:
* those referring to the 'py.test' executable
* those in code explicitly testing py.test/pytest module compatibility
* those in old CHANGES documentation
* those in documentation generated based on external data
* those in seemingly unfinished & unmaintained Japanese documentation
Minor stylistic changes and typo corrections made to documentation next to
several applied py.test --> pytest content changes.
