这是我的测试基类的摘录,它将apply_async
方法和记录到对它的调用(包括Task.delay
.) 。这有点恶心,但在过去几个月我一直在使用它时,它设法满足了我的需求。
from django.test import TestCase
from celery.task.base import Task
# For recent versions, Task has been moved to celery.task.app:
# from celery.app.task import Task
# See http://docs.celeryproject.org/en/latest/reference/celery.app.task.html
class CeleryTestCaseBase(TestCase):
def setUp(self):
super(CeleryTestCaseBase, self).setUp()
self.applied_tasks = []
self.task_apply_async_orig = Task.apply_async
@classmethod
def new_apply_async(task_class, args=None, kwargs=None, **options):
self.handle_apply_async(task_class, args, kwargs, **options)
# monkey patch the regular apply_sync with our method
Task.apply_async = new_apply_async
def tearDown(self):
super(CeleryTestCaseBase, self).tearDown()
# Reset the monkey patch to the original method
Task.apply_async = self.task_apply_async_orig
def handle_apply_async(self, task_class, args=None, kwargs=None, **options):
self.applied_tasks.append((task_class, tuple(args), kwargs))
def assert_task_sent(self, task_class, *args, **kwargs):
was_sent = any(task_class == task[0] and args == task[1] and kwargs == task[2]
for task in self.applied_tasks)
self.assertTrue(was_sent, 'Task not called w/class %s and args %s' % (task_class, args))
def assert_task_not_sent(self, task_class):
was_sent = any(task_class == task[0] for task in self.applied_tasks)
self.assertFalse(was_sent, 'Task was not expected to be called, but was. Applied tasks: %s' % self.applied_tasks)
这是一个“头脑风暴”示例,说明如何在测试用例中使用它:
mymodule.py
from my_tasks import SomeTask
def run_some_task(should_run):
if should_run:
SomeTask.delay(1, some_kwarg=2)
test_mymodule.py
class RunSomeTaskTest(CeleryTestCaseBase):
def test_should_run(self):
run_some_task(should_run=True)
self.assert_task_sent(SomeTask, 1, some_kwarg=2)
def test_should_not_run(self):
run_some_task(should_run=False)
self.assert_task_not_sent(SomeTask)
