使用模拟的返回值修补 Celery 任务调用,<Mock name='mock().get()' ...>
而不是return_value
由mock_task.get.return_value = "value"
. 但是,模拟任务在我的单元测试中正常运行。
这是我正在修补 Celery 任务的单元测试:
def test_foo(self):
mock_task = Mock()
mock_task.get = Mock(return_value={'success': True})
print mock_task.get() # outputs {'success': True}
with patch('app.tasks.my_task.delay', new=mock_task) as mocked_task:
foo() # this calls the mocked task with an argument, 'input from foo'
mock_tasked.assert_called_with('input from foo') # works
这是正在测试的功能:
def foo():
print tasks.my_task.delay # shows a Mock object, as expected
# now let's call get() on the mocked task:
task_result = tasks.my_task.delay('input from foo').get()
print task_result # => <Mock name='mock().get()' id='122741648'>
# unexpectedly, this does not return {'success': True}
if task_result['success']:
...
最后一行加注TypeError: 'Mock' object has no attribute '__getitem__'
为什么我可以在我的单元测试中调用 mock_task.get() ,但调用它会foo
返回 a<Mock ...>
而不是预期的返回值?
