[ckan-dev] Running tests that rely on a background job

Wed Jan 31 07:57:58 UTC 2018

Hi Nevelina,

I think your best option is to mock the enqueue_job function so that it 
executes the task it got passed synchronously instead of asynchronously. 
Something like this (untested):

import mock

def sequential_enqueue_job(job_func, args=None, kwargs=None, title=None):
    args = args or []
    kwargs = kwargs or {}
    job_func(*args, **kwargs)

@mock.patch('ckan.plugins.toolkit.enqueue_job', 
side_effect=sequential_enqueue_job)
def test_some_background_job(enqueue_job_mock):
    some_function_that_enqueues_a_job()
    assert something

You will probably have to adjust some details, but that should get you 
going.

For an example, see the tests of ckanext-extractor, where we've used this 
approach quite a bit:

https://github.com/stadt-karlsruhe/ckanext-extractor/blob/9-new-background-task-system/ckanext/extractor/tests/test_plugin.py

Best regards,
Florian
