Test email does not arrive in mail.outbox when sent by Django-RQ worker

Question

I've set up a test within Django that sends an email, in the background, using Django-RQ.

I call the code that enqueues the send_email task, then, I get the django-rq worker, and call .work(), with burst=True.

In my console, I can see the django-rq worker picking up the job, and confirming that it's been processed successfully. However, the email never arrives in Django's test mail.outbox.

Here is the test code:

    def test_reset_password(self):
        c = Client()
        page = reverse_lazy("accounts:password_reset")
        response = c.post(page, {'email': 'joe@test.co.uk'})
        self.assertRedirects(response, reverse_lazy("accounts:login"), 302, 200)
        
        django_rq.get_worker(settings.RQ_QUEUE).work(burst=True)

        self.assertEqual(len(mail.outbox), 1)
        self.assertEqual(mail.outbox[0].subject, 'Password reset instructions')

And here's the output from the console when the test is run:

Is it possible the email is going to a different instance of the django.core.mail.mailbox ? and if so, is there an effective way to unit test emails, in this context ?
