#2243: Regression: SQLAlchemy is not properly set up in test environments
------------------------+---------------------------------------------------
Reporter: Gustavo | Owner:
Type: defect | Status: new
Priority: highest | Milestone: 2.0rc1
Component: TurboGears | Version: trunk
Severity: blocker | Keywords:
------------------------+---------------------------------------------------
To reproduce the bug, copy/paste the following method of !RootController:
{{{
@expose('authproj.templates.index')
def show_email(self, userid):
user = model.User.by_user_name(userid)
flash('The email address is: %s' % user.email_address)
return dict(page='email')
}}}
Next, test it with the following code:
{{{
def test_email(self):
# Adding the user:
manager = User(user_name=u'manager',
email_address=u'[email protected]')
DBSession.add(manager)
DBSession.flush()
# Checking that it works:
resp = self.app.get('/show_email/manager', status=200)
assert "The email address is: [email protected]" in
resp.body, resp.body
}}}
The result?
{{{
ERROR:
authproj.tests.functional.test_authentication.TestAuthentication.test_email

This bug is also present in TG 2.0b5, when it was not necessary to add the
user manually because "paster setup-app ..." was run.
I'll also attach a test case which verifies that the same bug occurs at
the middleware level (on ingress).
