internally keep multiple applications of the same markers as separate
entities such that the new iter() API can iterate over pytest.mark function attributes, getting all such applications. See added example for more info.

Reading markers which were set from multiple places

----------------------------------------------------

.. versionadded: 2.2.2
|
||||
|
||||
If you are heavily using markers in your test suite you may encounter the case where a marker is applied several times to a test function. From plugin
|
||||
code you can read over all such settings. Example::
|
||||
|
||||
# content of test_mark_three_times.py
|
||||
import pytest
|
||||
pytestmark = pytest.mark.glob("module", x=1)
|
||||
|
||||
@pytest.mark.glob("class", x=2)
|
||||
class TestClass:
|
||||
@pytest.mark.glob("function", x=3)
|
||||
def test_something(self):
|
||||
pass
|
||||
|
||||
Here we have the marker "glob" applied three times to the same
|
||||
test function. From a conftest file we can read it like this::
|
||||
|
||||
# content of conftest.py
|
||||
|
||||
def pytest_runtest_setup(item):
|
||||
g = getattr(item.obj, 'glob', None)
|
||||
if g is not None:
|
||||
for info in g:
|
||||
print ("glob args=%s kwargs=%s" %(info.args, info.kwargs))
|
||||
|
||||
