Flask test client refuse arobase in data? - flask

Question

I'm trying to set up tests in my Flask but for an unknown reason, Flask fails when I add a parameter with arobase.
I followed the snippet here http://flask.pocoo.org/snippets/26/ and can make a successful request (it works), but when I try to do a post, it fails (with the following exception) :
def test_auth_login_fail(self):
""" Login fail """
result = self.client.post(self._make_url("/auth/login"), data=dict(
email="user#website.com",
password='cxcxz'
))
self.assertEqual(result.status_code, 404)
And the exception :
Traceback (most recent call last):

app_iter = app(environ, start_response)
TypeError: 'tuple' object is not callable
For informations, this doesn't generate an exception :
def test_auth_login_fail(self):
""" Login fail """
result = self.client.post(self._make_url("/auth/login"), data=dict(
email="userwebsite.com",
password='cxcxz'
))
self.assertEqual(result.status_code, 404)
(notice the "#" removed)
I also removed the Middleware (indicated in the traceback) without much success.
What am I missing ?

Looks like in case of an email is correct, you return something wrong (a tuple) from your view function. And when you pass a malformed email, the value you return is ok.
