django - 如何使用模拟数据测试 Stripe Webhook

Question

我正在尝试编写一个单元测试，将模拟事件发布到我的 stripe webhook。

我去从我的日志中提取了一个事件，并尝试在启用测试模式的情况下发送它，但是我(有点可以预见)得到了一个错误:

a similar object exists in live mode, but a test mode key was used to make this request.

很公平。那么我该如何创建一个模拟事件，我可以实际将其发送到我的 webhook 并正确处理它呢？

这是我当前的测试:

class StripeTest(TestCase):
    def setUp(self):
        self.client = Client()

    def test_receiving_a_callback(self):
        with open('donate/test_assets/stripe_event.json', 'r') as f:
            stripe_event = simplejson.load(f)

        self.client.post('/donate/callbacks/stripe/',
                         data=simplejson.dumps(stripe_event),
                         content_type='application/json')

解决方案是创建您自己的模拟数据。在下面的代码中，我们通过创建 strip token 来创建测试支付，然后通过前端(在/donate/端点)提交它。

前端正常工作后，您可以从 stripe 获取事件，然后将其发送到开发机器的 webhook 端点。

这比我预期的要多，而且我不喜欢我的测试进入网络，但这似乎是一个不错的解决方案。我对自己的付款比以前更有信心。

    def test_making_a_donation_and_getting_the_callback(self):
        """These two tests must live together because they need to be done sequentially.

        First, we place a donation using the client. Then we send a mock callback to our
        webhook, to make sure it accepts it properly.
        """
        stripe.api_key = settings.STRIPE_SECRET_KEY
        # Create a stripe token (this would normally be done via javascript in the front
        # end when the submit button was pressed)
        token = stripe.Token.create(
            card={
                'number': '4242424242424242',
                'exp_month': '6',
                'exp_year': str(datetime.today().year + 1),
                'cvc': '123',
            }
        )

        # Place a donation as an anonymous (not logged in) person using the
        # token we just got
        r = self.client.post('/donate/', data={
            'amount': '25',
            'payment_provider': 'cc',
            'first_name': 'Barack',
            'last_name': 'Obama',
            'address1': '1600 Pennsylvania Ave.',
            'address2': 'The Whitehouse',
            'city': 'DC',
            'state': 'DC',
            'zip_code': '20500',
            'email': 'barack@freelawproject.org',
            'referrer': 'footer',
            'stripeToken': token.id,
        })

        self.assertEqual(r.status_code, 302)  # 302 because we redirect after a post.

        # Get the stripe event so we can post it to the webhook
        # We don't know the event ID, so we have to get the latest ones, then filter...
        events = stripe.Event.all()
        event = None
        for obj in events.data:
            if obj.data.object.card.fingerprint == token.card.fingerprint:
                event = obj
                break
        self.assertIsNotNone(event, msg="Unable to find correct event for token: %s" % token.card.fingerprint)

        # Finally, we can test the webhook!
        r = self.client.post('/donate/callbacks/stripe/',
                             data=simplejson.dumps(event),
                             content_type='application/json')

        # Does it return properly?
        self.assertEqual(r.status_code, 200)
