How can I auto-specialize the mocking function of Celery

Question

Given a celery job, what is the easiest way to mock a function using autospec?

For example, in python Python 2.7.5 this code will go fine:

from mock import create_autospec
from celery import task

@task
def function(a, b, c):
    pass

mock_function = create_autospec(function)
mock_function.delay('wrong arguments')

When it should throw an exception because the celery "delay" method will accept any parameter.

In fact, you are trying to check the arguments of the Task.run () function.

See the docs below: http://celery.readthedocs.org/en/latest/userguide/tasks.html#custom-task-classes http://celery.readthedocs.org/en/latest/reference/celery.app. task.html # celery.app.task.Task.run

run() , . , , :

from mock import create_autospec
from celery import task

@task
def function(a, b, c):
    pass

mock_function = create_autospec(function)
mock_function.run('wrong arguments')

TypeError: <lambda>() takes exactly 4 arguments (2 given)
