This works by adding an argparse Action that will raise an exception in
order to skip the rest of the argument parsing. This prevents argparse
from quitting due to missing required arguments, similar to the way that
the builtin argparse --help option is implemented by raising SystemExit.
Fixes: #1999
When using both --last-failed/--lf and --failed-first/--ff pytest would
run all tests with failed tests first (as if --lf was not provied). This
patch changes it so that when using both flags, only the last failed
tests are run. This makes it easier to set --ff as the default behavior
via the config file and then selectively use --lf to only run the last
failed tests.
In a recent refactoring we enabled all __future__ features in pytest
modules, but that has the unwanted side effect of propagating those
features to compile()'d modules inside assertion rewriting, unless
we pass dont_inherit=False to compile().
For some reason pypy raises this warning in the line that the catch_warnings block was added:
______________________________ ERROR collecting ______________________________

this allows a clear addition of parameterization parameters that carry along marks
instead of nesting multiple mark objects and destroying the possibility of creating
function valued parameters,
it just folders everything together into one object carrfying parameters, and the marks.
Change XML file structure in the manner that failures in call and errors
in teardown in one test will appear under separate testcase elements in
the XML report.
In the xml report we now have two occurences for the system-out tag if
the testcase writes to stdout both on call and teardown and fails in
teardown.
This behaviour is against the xsd.
This patch makes sure that the system-out section exists only
once per testcase.
This has the benefical side-effect of not calling the original
warnings.showwarnings function, which in its original form
only writes the formatted warning to sys.stdout.
Calling the original warnings.showwarnings has the effect that nested WarningsRecorder all catch the warnings:
with WarningsRecorder() as rec1:
with WarningsRecorder() as rec2:
warnings.warn(UserWarning, 'some warning')
(both rec1 and rec2 sees the warning)
When running tests with `testdir`, the main pytest session would then see the warnings created by
the internal code being tested (if any), and the main pytest session would end up with warnings as well.
Descriptors (e.g. properties) such as in the added test case are
triggered during collection, executing arbitrary code which can raise.
Previously, such exceptions were propagated and failed the collection.
Now these exceptions are caught and the corresponding attributes are
silently ignored.
A better solution would be to completely skip access to all custom
descriptors, such that the offending code doesn't even trigger. However
I think this requires manually going through the instance and all of its
MRO for each and every attribute checking if it might be a proper
fixture before accessing it. So I took the easy route here.
In other words, putting something like this in your test class is still
a bad idea...:
@property
def innocent(self):
os.system('rm -rf /')
Fixes#2234.
Currently if the terminal report of testdir.runpytest() is missing,
assert_outcomes() on its output fails because parseoutcomes()
returns an unexpected value (None).
It's better to fail parseoutcomes() directly.
Those tests originally checked for ImportError. Since Python 3.6
ModuleNotFoundError is raised in this context instead, the tests didn't work
as they are text based (so exception inheritance does not save the day).

This commit also improves readbility in get_dirs_from_args by using self
documenting local functions.
get_dirs_from_args also now only returns directories that actually exists,
and not files to avoid confusion.
This commit also removes redundant checks in get_common_ancestor that
was already performed in get_dirs_from_args..
