Question

我当前正在尝试测试（pytest）我的Django信号。我总是在这里收到此错误：

E           AssertionError: Expected call: mock(sender=<ANY>, signal=<django.dispatch.dispatcher.Signal object at 0x10a29f668>)
E           Actual call: mock(charge={[...]]}, order=Order: #weGnyRDPOL, sender=<class 'type'>, signal=<django.dispatch.dispatcher.Signal object at 0x10a29f668>)

我的信号包含打印语句：

@receiver(signal=charge_succeeded)
def create_influencer_transaction(sender, order, charge, **kwargs):
    print("TEST")

显示执行pytest TEST时，但是上面的错误停止了我的测试。你知道我的考试怎么了吗？

@contextmanager
def catch_signal(signal):
    """Catch django signal and return the mocked call."""
    handler = mock.Mock()
    signal.connect(handler)
    yield handler
    signal.disconnect(handler)


@pytest.fixture
def tester():
    return StripeTester()

@pytest.mark.django_db
def test_should_send_signal_when_charge_succeeds(client, monkeypatch, tester):
    with catch_signal(charge_succeeded) as handler:
        # Charge normally are several lines of code that also include
        # client, monkeypatch, tester. However, that part works as I 
        # receive the signal (see below). That's why I simplified it.
        charge(100)
    handler.assert_called_once_with(
        sender=mock.ANY,
        signal=charge_succeeded,
    )

用Mock测试Django信号
