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.

The result from the pytest_assertrepr_compare hook should not include
any newlines since that will confuse the mini-formatting language used
by assertion.util.format_explanation. So simply escape the included
newlines, this way hook writers do not have to worry about this at
all.
Fixes issue 453.
line arguments by using the result of parse_known_args rather than
the previous flaky heuristics. Thanks Marc Abramowitz for tests
and initial fixing approaches in this area.
Casting of fd can break for non-numeric fd (e.g.: "rtd" on Linux) and isn't
necessary since we don't need to sort.

Prevent error on exit if some code messes with sys.meta_path and removes the
assertionrewrite hook (CaptureMock seems to do this):

sys.meta_path.remove(hook)
ValueError: list.remove(x): x not in list

- avoid resetting capture FDs/sys.stdout for each test by keeping capturing
always turned on and looking at snapshotted capturing data during runtest
and collection phases.
between working at the front and at the end of a hook call chain.
The idea is to make it easier for a plugin to "wrap" a certain hook
call and use context managers, in particular allow a major cleanup of
capturing.
- node.warn() for a node-specific warning
- config.warn() for a global non-node specific warning
Each warning is accompanied by a "warning number" so that we can later
introduce mechanisms for surpressing them.
Each warning will trigger a call to pytest_report_warn(number, node, message)
which is by default implemented by the TerminalReporter which introduces
a new option "-rw" to show details about warnings.
If the compared text was in bytes and not actually valid text
(i.e. could not be encoded to text/unicode using the default encoding)
then the assertrepr would fail with an EncodingError. This ensures
that the internal string is always valid unicode, converting any bytes
safely to valid unicode. This is done using repr() which then needs
post-processing to fix the encompassing quotes and un-escape newlines.
This fixes issue 429.
When pytest is called with the '--markers' option, it should collect marker
information from the current folder, and they should get loaded and used
correctly before the '--markers' output is constructed.
When a MarkDecorator instance is called it does the following:
1. If called with a single class as its only positional argument and no
additional keyword arguments, it attaches itself to the class so it gets
applied automatically to all test cases found in that class.
2. If called with a single function as its only positional argument and no
additional keyword arguments, it attaches a MarkInfo object to the
function, containing all the arguments already stored internally in the
MarkDecorator.
3. When called in any other case, it performs a 'fake construction' call, i.e.
it returns a new MarkDecorator instance with the original MarkDecorator's
content updated with the arguments passed to this call.
When Python applies a function decorator it always passes the target class/
function to the decorator as its positional argument with no additional
positional or keyword arguments. However, when MarkDecorator was deciding
whether it was being called to decorate a target function/class (cases 1. & 2.
as documented above) or to return an updated MarkDecorator (case 3. as
documented above), it only checked that it received a single callable positional
argument and did not take into consideration whether additional keyword
arguments were being passed in as well.
With this change, it is now possible to create a pytest mark storing a function/
class parameter passed as its only positional argument and accompanied by one or
more additional keyword arguments. Before, it was only possible to do so if the
function/class parameter argument was accompanied by at least one other
positional argument.
Added a related unit test.
Updated MarkDecorator doc-string.
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.
