Comment (by cjerdonek):
One use case is the following. Say you have some views that return JSON.
And say they're set up so that if `DEBUG` is enabled and there is a
server-side error, the JSON includes detailed exception info (analogous to
the HTML debug view). Otherwise, only a failure status code is returned.
And further say you have tests that involve calling these views and
checking the response.
If there is a server-side error when calling these views during a test,
the absence of any exception info can make the test hard to troubleshoot.
I found that having to edit the code manually each time there was such an
error to change the settings for that test was unnecessarily time-
consuming.
Another use case is if your code includes additional asserts when running
in `DEBUG` mode.
Regarding an expectation that tests pass in `DEBUG`, I think you could
simply document that it not be necessary. Or perhaps only allow the
`--debug` option when test labels are also passed to the command (i.e.
disallow the option when running all tests). In my experience, I've only
had a need to use it when troubleshooting individual tests.
