Python unittest task.apply_async()

Question

Using coverage to look what has to be tested, and coverage shows that next to this has to be tested: send_alert.apply_async()

I know it is celery task, but is there any way to test the line of code?

rest of code to understand logic for test:

class SomeView(GenericAPIView)
    def post(self, request, *args, **kwargs):
        #some code
        if not value:
           send_alert.apply_async()
           # response
        # not if Response

Test written due to first answer

    @patch('event.views.send_alert')
    def test_send_alert(self, mock_send):
        data = {some data for post}
        response = self.client.post('/api/{0}/mettings/'.format(self.user), data)
        print(response.json())
        self.assertTrue(mock_send.called)

Also i check in view that after task print('Tasks Passed') and i see message that tasks passed, but test failed with error AssertionError: False is not true

I'm assuming you are using Django, as this is tagged that way.

Decorate your test with:

@override_settings(CELERY_EAGER=True)
def test_foo(self):
    # Make your post

Or if you just want to test that it is called.

from mock import patch

@patch('your_module.your_file.send_alert.apply_async')
def test_foo(self, mock_send):
    # make your post with "value" set to True
    self.assertTrue(mock_send.called)
