I'm using pytest.
I would like to gather/save some data for postmortem analysis on a test failure. I can write a teardown_method, but I don't see a way to obtain test status in that context.
Is it possible to take an action on any test (or assertion) failure?

The plugin provides two command line options to rerun failures from the last pytest invocation: --lf , --last-failed - to only re-run the failures. --ff , --failed-first - to run the failures first and then the rest of the tests.
The simplest way to skip a test function is to mark it with the skip decorator which may be passed an optional reason : @pytest. mark.
Pytest only caches one instance of a fixture at a time, which means that when using a parametrized fixture, pytest may invoke a fixture more than once in the given scope.
Summary. You can pass arguments to fixtures with the params keyword argument in the fixture decorator, and you can also pass arguments to tests with the @pytest. mark. parametrize decorator for individual tests.
Implement a pytest_exception_interact in a conftest.py file, which according to the documentation:
called when an exception was raised which can potentially be interactively handled.
def pytest_exception_interact(node, call, report):
if report.failed:
# call.excinfo contains an ExceptionInfo instance
It's not clear from your question exactly what you want to gather from the error, but probably having access to an ExceptionInfo instance should be enough for your case.

You can also do it in the second half of a yield fixture:
