我正在測試使用動態創建函數的返回值的代碼。 我需要確保我正在測試的代碼調用一個名爲'email_invoice'與欺騙性數據...模擬測試動態函數的返回值
動態創建的函數命中遠程系統,所以我僞造呼叫的結果。
class MyTest(unittest2.Test):
def setUp(self):
patcher = mock.patch('soc.product.views.API')
patch = patcher.start()
self.order_id = 'fake_order_id'
# The `API` class has methods that are dynamically created.
# The method `API.CreateOrder` needs to be patched to return `self.order_id`
# When testing that a resulting method is called, I get a failed assertion:
#AssertionError: Expected call: email_invoice(<User: User(id=46, merchant_id=503579)>, 'fake123123123')
#Actual call: email_invoice(<User: User(id=46, merchant_id=503575)>, <MagicMock name='API().CreateOrder().OrderID' id='140700602174736'>)
# soc.product.views.API.CreateOrder => self.order_id
CreateOrderResult = mock.NonCallableMock()
CreateOrderResult.OrderId = self.order_id
patch.CreateOrder = mock.Mock()
patch.CreateOrder.return_value = CreateOrderResult
def test_that_stuff_out_homie(self):
... doing stuff ...
user = ... a result of doing stuff ...
self.patches['email_invoice'].assert_called_once_with(user, self.order_id)
因爲它提到,斷言失敗是這樣的:
AssertionError: Expected call: email_invoice(<User: User(id=46, merchant_id=503579)>, 'fake123123123')
Actual call: email_invoice(<User: User(id=46, merchant_id=503575)>, <MagicMock name='API().CreateOrder().OrderID' id='140700602174736'>)
那麼,什麼是測試這一點,正確的/正確的方法是什麼?
您正在將'self.order_id'分配給'OrderId',但是通過'OrderID'從API獲取id(注意字符串末尾的大寫) –
將此作爲答案並且我可以接受... –
