I have a common py.test fixture that I want to use generically in different test files within the same module. After reading the py.test documentation, the suggestion was to add the fixture to a conftest.py
file which should make the fixture available to all files in the module. But for some reason, I can't seem to get this common fixture to work with my test class.
#In conftest.py
import pytest
@pytest.fixture
def mock_data(scope="module"):
return ({'number_of_females_1': 14,
'number_of_females_2': 3,
'number_of_females_3': 19,
'number_of_males_1': 37)}
Then in my test class file I have
Import pytest
from unittest import TestCase
@pytest.mark.usefixtures('mgmt_data')
class Test_param_sweeps(TestCase):
def test_Base_model(self, mgmt_data):
from pyugend.pyugend.Models import Base_model
t = Base_model(**mgmt_data)
assert isinstance(t, Base_model)
The documentation said that I did not have to import the mgmt_data
fixture or anything.
The error I get when running this test case is:
self = <pyugend.tests.test_param_sweeps.Test_param_sweeps testMethod=test_Base_model>
result = <TestCaseFunction 'test_Base_model'>
def run(self, result=None):
orig_result = result
if result is None:
result = self.defaultTestResult()
startTestRun = getattr(result, 'startTestRun', None)
if startTestRun is not None:
startTestRun()
result.startTest(self)
testMethod = getattr(self, self._testMethodName)
if (getattr(self.__class__, "__unittest_skip__", False) or
getattr(testMethod, "__unittest_skip__", False)):
# If the class or method was skipped.
try:
skip_why = (getattr(self.__class__, '__unittest_skip_why__', '')
or getattr(testMethod, '__unittest_skip_why__', ''))
self._addSkip(result, self, skip_why)
finally:
result.stopTest(self)
return
expecting_failure_method = getattr(testMethod,
"__unittest_expecting_failure__", False)
expecting_failure_class = getattr(self,
"__unittest_expecting_failure__", False)
expecting_failure = expecting_failure_class or expecting_failure_method
outcome = _Outcome(result)
try:
self._outcome = outcome
with outcome.testPartExecutor(self):
self.setUp()
if outcome.success:
outcome.expecting_failure = expecting_failure
with outcome.testPartExecutor(self, isTest=True):
> testMethod()
E TypeError: test_Base_model() missing 1 required positional argument: 'mgmt_data'
/home/krishnab/anaconda3/envs/py35_gu/lib/python3.5/unittest/case.py:600: TypeError
I am not sure that the error is? It says that I am missing a positional argument, but mgmt_data() does not take any arguments and the Base_model() class takes only one argument which is the **mgmt_data
.
