Isn't --no-cov
the flag you want?
I can do this piecemeal with flags, but I'd like something that does it automatically. If I just run one test and I forget to turn off coverage reporting it's annoying because I get the coverage report at the end. OTOH I could leave it off by default, but then if I run the full suite and forget to turn it on I would have to run the whole suite again.
I discovered an issue. The above doesn't work when using @pytest.mark.no_cover
.
self = <Collector at 0x7fed5bac29d0: CTracer>
def stop(self):
"""Stop collecting trace information."""
assert self._collectors
if self._collectors[-1] is not self:
print("self._collectors:")
for c in self._collectors:
print(f" {c!r}\n{c.origin}")
> assert self._collectors[-1] is self, (
f"Expected current collector to be {self!r}, but it's {self._collectors[-1]!r}"
)
E AssertionError: Expected current collector to be <Collector at 0x7fed5bac29d0: CTracer>, but it's <Collector at 0x7fed60d09c70: CTracer>
../../anaconda3/envs/ndindex/lib/python3.8/site-packages/coverage/collector.py:349: AssertionError
It seems the coverage object doesn't like having stop() called twice in a row on it without calling start() in between.
It turns out that even without the above change, --no-cov
also breaks when using @pytest.mark.no_cover
with an error like
self = <pytest_cov.plugin.CovPlugin object at 0x7ff226183700>, item = <Function test_sympy_dependency[_test_dependency_iter_indices]>
@compat.hookwrapper

if (item.get_closest_marker('no_cover')
or 'no_cover' in getattr(item, 'fixturenames', ())):
> self.cov_controller.pause()
E AttributeError: 'NoneType' object has no attribute 'pause'

I have a library that I am maintaining at 100% coverage, which I do by configuring coverage to fail below 100% and configuring pytest-cov with
--cov=mylib/ --cov-report=term-missing
inpytest.ini
. However, this report is useless whenever I run only a subset of the tests.I've been able to get the behavior I want using the hints from https://github.com/pytest-dev/pytest-cov/issues/418#issuecomment-657219659 with something like
However, it would be convenient if this were just a flag I could pass to pytest.
