copied!<p>The accepted answer didn't work for me. I use Selenium for testing, and setting <code>@override_settings(DEBUG=True)</code> makes the test browser always display <code>404</code> error on every page. And <code>DEBUG=False</code> does not show exception tracebacks. So I found a workaround.</p> <p>The idea is to emulate <code>DEBUG=True</code> behaviour, using custom <code>500</code> handler and built-in django <code>500</code> error handler. </p> <ol> <li><p>Add this to <em>myapp.views:</em></p> <pre><code>import sys from django import http from django.views.debug import ExceptionReporter def show_server_error(request): """ 500 error handler to show Django default 500 template with nice error information and traceback. Useful in testing, if you can't set DEBUG=True. Templates: `500.html` Context: sys.exc_info() results """ exc_type, exc_value, exc_traceback = sys.exc_info() error = ExceptionReporter(request, exc_type, exc_value, exc_traceback) return http.HttpResponseServerError(error.get_traceback_html()) </code></pre></li> <li><p><em>urls.py:</em></p> <pre><code>from django.conf import settings if settings.TESTING_MODE: # enable this handler only for testing, # so that if DEBUG=False and we're not testing, # the default handler is used handler500 = 'myapp.views.show_server_error' </code></pre></li> <li><p><em>settings.py:</em></p> <pre><code># detect testing mode import sys TESTING_MODE = 'test' in sys.argv </code></pre></li> </ol> <p>Now if any of your Selenium tests encounters 500 error, you'll see a nice error page with traceback and everything. If you run a normal non-testing environment, default 500 handler is used.</p> <p>Inspired by: </p> <ul> <li><a href="https://stackoverflow.com/questions/12924746/where-in-django-is-the-default-500-traceback-rendered-so-that-i-can-use-it-to-cr">Where in django is the default 500 traceback rendered so that I can use it to create my own logs?</a></li> <li><a href="https://stackoverflow.com/questions/4088253/django-how-to-detect-test-environment">django - how to detect test environment</a></li> </ul>
