When the test logs in I am redirected to the main webpage which is localhost:46497/ but instead of the page I am getting Server Error 500. This error occurs only when testing. In addition, if I add another path e.g. localhost:46497/analytics it opens the webpage as expected.

Any help would be appreciated.

After 4 hours of debugging, I found out that the issue was related to the database being empty.

The webpage that I wanted to render is expecting some models to be passed, and since the DB was empty those models weren't passed and hence the crash. In normal circumstances ( ./manage.py runserver) if DEBUG=True it will tell you what is wrong, but for some reason StaticLiveServerTestCase doesn't have this option or at least I am not aware of it. If anyone knows how to enable some debugger for the StaticLiveServerTestCase please feel free to add to this thread.

So what I did: ./manage.py dumpdata order.tax > data.json - I dumped the data that I needed into a json file and at the beginning of the TestCase I added that data into the fixture

Hope this helps someone with the same issue!
