Unit testing in Django

Question

Let's suppose I do some change to a function in the tests.py file, like monkey patching the clean method of some form...

When all the tests are finished, will that method still have associated the function I assigned?

A concrete example (to avoid captcha validation when testing):

from myapp.fields import ReCaptchaField
ReCaptchaField.clean = lambda x, y: y[0]

The same applies to adding/changing some field in the settings.py file...

Answer 1

Yes, it will remain associated. That's the benefit/side-effect/danger of monkey-patching, change the default behavior during the process lifetime.
