New issue 441: parametrized fixture + module scope + failing test + '-x' option
= invalid fixture finalizer output
https://bitbucket.org/hpk42/pytest/issue/441/parametrized-fixture-module-scope-failing
Jurko Gospodnetić:
The following test demonstrates the issue. You can run it as a part of the
internal pytest test suite.
```
import fnmatch
def test_module_fixture_finalizer_output_capture(testdir):
"""
Demonstrates a fixture finalizer output capture defect in pytest 2.5.0.
pytest should not allow any test script output to be displayed uncontrolled
unless its output capture has been disabled.
If we have a parametrized module scoped fixture and a failing test using
that fixture then running the test suite with the '-x' option seems to
produce uncaptured fixture finalizer output (first fixture parametrization
only).
"""
testdir.makepyfile(r"""\
import pytest
@pytest.fixture(scope="module", params=["A", "B"])
def ola(request):
print("<I AM NOT HERE> fixture (%s)" % (request.param,))
class frufru:
def __init__(self, param):
self.param = param
def __call__(self):
print("<I AM NOT HERE> finalizer <%s>" % (self.param,))
request.addfinalizer(frufru(request.param))
return request.param
def test_me(ola):
print("<I AM NOT HERE> test <%s>" % (ola,))
pytest.fail()
""")
# Using '--tb=no' should prevent all regularly captured test output to be
# displayed. Using '-q' simply removes some irrelevant test output thus
# making this external test's failure output shorter.
for extra_params in ([], ["-x"]):
output = testdir.runpytest("--tb=no", "-q", *extra_params).stdout.lines
for line_index, line in enumerate(output):
assert "<I AM NOT HERE>" not in line
```
Hope this helps.
Best regards,
