Adding an 'if testing' check is probably not the best approch. This would introduce a distinction in your code between 'real' code and 'test' code; in effect, any code in the 'real' branch would never get tested. The risk associated with this could be mediated in practice (by minimizing the code you put in such a conditional), but it would be better to avoid the problem entirely. The approach that is taken by the Django test system is to instrument those parts of Django that are have external effects. For example, if you have a view that sends notification emails, you don't want each execution of a test to send those emails, and it would be nice to be able to check to see which emails were actually sent. To accommodate this, the Django test framework dynamically replaces the send_mail function with a mock version during test setup. The email mock object provides the same interface as the real thing, but puts all sent messages into local store, rather than posting to SMTP. The end user code calling send_mail is never aware of the change - and no 'if testing' code is required. You can do a similar thing for any calls that have external effects. Look at setup_test_environment in django.test.utils for details of how the job is done for email; the same approach should work as a general technique.
