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.
KeyboardInterrupt is a subclass of BaseException, but not of Exception.
Hence if we remove this except, KeyboardInterrupts will still be raised
so the behavior stays the same.
