Django Test framework with file based Email backend server

I have formulated test cases in Django framework.

Use Case: I am using API that register user by sending them an Email and when they click on the link provided in the Email their account get activated.

In my settings.py I am using

EMAIL_FILE_PATH  ='django.core.mail.backends.filebased.EmailBackend'

which points to the local directory.

When running PyUnit test case from eclipse everything works file. Text file gets generated for each email sent

But, When i am using

python ./manage.py test <component_name>

the files does not generate.

Any insight what is the difference when I execute test case with ./manage.py and when I use pyUnit ?

The simple answer:

You can’t do this without engineering your own email system, but that would probably be silly. I would suggest doing something else to verify that the code was successful without requiring the email to be sent. Like, run the code, assume the user clicks the link and create RequestFactory to get/post the link to run the view code associated with it.

From the Django Testing Application:

Email services

"If any of your Django views send email using Django's email functionality,
you probably don't want to send email each time you run a test using that
view. For this reason, Django's test runner automatically redirects all
Django-sent email to a dummy outbox. This lets you test every aspect of
sending email -- from the number of messages sent to the contents of each
message -- without actually sending the messages."
