Testings Tasks about django-background-tasks

[jvamvas]

Here's an example:

from django.test import TestCase

from background_task import background
from background_task.tasks import tasks


completed_tasks = []

@background()
def my_background_task(message):
    completed_tasks.append(message)


class MyBackgroundTaskTestCase(TestCase):
    def test_run_task(self):
        my_background_task(message="test")
        tasks.run_next_task()
        self.assertTrue("test" in completed_tasks)

The management command process_tasks might be a helpful reference: https://github.com/arteria/django-background-tasks/blob/master/background_task/management/commands/process_tasks.py#L85

Thanks. That would work. But let's say I have a function used all over the code like send_email. And I decorate it to now be a background task.

Would I need to go into every single test and tell it to run_next_task(). Would there be a way to do this automatically everywhere?

You can use .task_function field of your task:

@background
def add(x,y):
    return x+y

add(1,2)  # will create a task
add.task_function(1,2)   # will launch your function immediatly and synchronously
add = add.task_function  # permanently rid out of background stuff for testing purpose

Also check out this PR lilspikey#17 (comment). I accidentally pushed it to wrong repo.
