PicklingError using live_server fixture on Windows #54
Description
Not sure if Windows is supposed to be supported, but for me it fails on Windows 10 Python 2.7.12 with the following error when live_server fixture used:
request = <SubRequest '_push_request_context' for <Function 'test_get_url'>>
@pytest.fixture(autouse=True)
def _push_request_context(request):
"""During tests execution request context has been pushed, e.g. `url_for`,
`session`, etc. can be used in tests as is::
def test_app(app, client):
assert client.get(url_for('myview')).status_code == 200
"""
if 'app' not in request.fixturenames:
return
app = request.getfuncargvalue('app')
# Get application bound to the live server if ``live_server`` fixture
# is applyed. Live server application has an explicit ``SERVER_NAME``,
# so ``url_for`` function generates a complete URL for endpoint which
# includes application port as well.
if 'live_server' in request.fixturenames:
> app = request.getfuncargvalue('live_server').app
