This commit also:
- Dramatically increases the number of unit tests , mostly by borrowing
from the standard library's unit tests for math.isclose().
- Refactors approx() into two classes, one of which handles comparing
individual numbers (ApproxNonIterable) and another which uses the
first to compare individual numbers or sequences of numbers.
When defining a fixture in the same module as where it is used, the
function argument shadows the fixture name, which a) annoys pylint and
b) can lead to bugs where you forget to request a fixture into a test
method.
This allows one to define fixtures with a different name than the name
of the function, bypassing that problem.
This was a challenge because it had to work in python2 and python3,
which have almost opposite unicode models, and I couldn't use the six
library. I'm also not sure the solution I found would work in python3
before python3.3, because I use the u'' string prefix which I think was
initially not part of python3.
When we have a metaclass which returns something truthy (like a method) in its
__getattr__, we collected the class because pytest thought its __test__
attribute was set to True.
We can work around this to some degree by assuming __test__ will always be set
to an explicit True if that's what the user has intended, and if it's something
other than that, this is probably a mistake.
Fixes#1204.
When an object has a custom __getattr__ which always returns a non-int, we
tried to get compat_co_firstlineno from it and checked it was a integer, which
caused an exception if such a class is mistakenly collected.
If we still mistakenly collect such a class (which is likely to be something
other than a test), we now skip it with a warning (because it probably has an
__init__) instead of producing an error.
See #1204.
Fixes issue 331
previously to this change the collection code would issue a warning for
when ever it encountered a variable that looked like a test but wasn't a
function saying that it wouldn't collect it because it wasn't a function.
This fixes the logic so that if that warning is issued it really isn't
collected.
However previously special cases existed to support tests that were
created using functools.wraps and functools.partial. So the condition for
issuing that warning has been updated to take that in to account
Also try the old way of detecting functions just for proper integration
with mock.path in python 2.7 the get_real_func returned the unbound method
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.
- integrate conftest into pytester plugin
- introduce runpytest() to either call runpytest_inline (default) or
runpytest_subprocess (python -m pytest)
- move testdir.inline_runsource1 to pdb tests
- strike some unneccessary methods.
- a new section "writing plugins" and some better pytester docs

branch : testrefactor
instead of prepending. This better allows to run test modules
against installated versions of a package even if the package
under test has the same import root. In this example::
testing/__init__.py
testing/test_pkg_under_test.py
pkg_under_test/
the tests will preferrably run against the installed version
of pkg_under_test whereas before they would always pick
up the local version.

CWD outside a test package pytest would get fixture discovery wrong.
Thanks to Wolfgang Schnerring for figuring out a reproducable example.

branch : conftest-nodeid
This strips the line number, /@\d/, from the verbose output so it is
directly the node ID of the test. This in turn means no special logic
for accepting the line number as part of the node ID is needed when
parsing the command line.
The new "--tb=auto" option (default) will only display long tracebacks
for the first and last entry. You can get the old behaviour of printing
all entries as long entries with "--tb=long". Also short entries by
default are now printed very similarly to "--tb=native" ones.
Without this if a session scoped fixture fails it's setup it will
be re-tried each time it is requested. Especially in case of
skip or failure exceptions this can be undesirable, but caching
makes sense for all exceptions.
If the type is not checked then an incomprehensible error will occur
later. This enforces the type and raies the same exception/msg as
CPython does in that case.
Docstring unmodified, just re-justified for pep8 compat.
Replace the verbose per-test reporting format of `file:line test_name RESULT`
with the node ID of the test, i.e. `file@line::class::method[param] RESULT`.
This patch does not update the examples in the docs; @hpk42 has a script
to regenerate those.
