Test client doesn't allow testing 500 responses content

The test client is re-raising almost every single exception (as per, which means there is no way to get the response content back for responses returned by the 500 error handler. This prevents using the test client for testing an important area.

The test client works as documented, so it's not a bug.

In most cases this behavior is more useful then returning getting a generic error page. Using selenium is probably a better choice for testing your 500 pages, but I guess that having an option in the Client class could also be useful.

Is there any reason why TemplateView(template_name='500.html') is not sufficient for doing this?

comment:5 Changed 3 years ago by David Avs <david@…>

One reason is that handler500 sometimes could be a custom view. In this case TemplateView(...).as_view() may be not sufficient, but the handler500 can be used instead.

I am in the same situation as David. Our 500 page is a redirect that needs to be tested. Although it's a fairly easy to test for 404s and the like, we can't test that our 500 handler works.

Hi folks,

Currently I need to test not even 500 user-facing view, but email sending on 500.

Is there any way to trigger production error handling from within unit test with django client (or otherwise from unit test)?

I strongly hesitate to move this into Selenium integration tests due to need of full-fledged email mocking (instead of neat and sweet locmem email backend that I may use in unit tests).
