我怎么才能在Go中模仿Stripe呢？

Question

我正在试着模拟一些测试的条纹。

//testify mock
type Backend struct {
    mock.Mock
}

func (s Backend) Call(method, path, key string, params stripe.ParamsContainer, v interface{}) error {
    args := s.Called(params)
    return args.Error(0)
}

func (s Backend) CallRaw(method, path, key string, body *form.Values, params *stripe.Params, v interface{}) error {
    args := s.Called(params)
    return args.Error(0)
}

func (s Backend) CallMultipart(method, path, key, boundary string, body *bytes.Buffer, params *stripe.Params, v interface{}) error {
    args := s.Called(params)
    return args.Error(0)
}

func (s Backend) SetMaxNetworkRetries(maxNetworkRetries int) {
    s.Called(maxNetworkRetries)
}

然后在测试初始化中：

//stripe
backend := new(mock.Backend)
backend.On("CallRaw", testify.Anything, testify.Anything, testify.Anything, testify.Anything, testify.Anything).
    Return(nil)
backend.On("Call",
    testify.
        MatchedBy(func(req stripe.ParamsContainer) bool {
            customerParams, ok := req.(*stripe.CustomerParams)
            if ok {
                return *customerParams.Email == "failure@email.com"
            }
            return false
        })).
    Return(fmt.Errorf("downstream stripe error"))
backend.On("Call",
    testify.
        MatchedBy(func(req stripe.ParamsContainer) bool {
            customerParams, ok := req.(*stripe.CustomerParams)
            if ok {
                return *customerParams.Email == "success@email.com"
            }
            return false
        })).
    Return(nil)
sc := &client.API{}
sc.Init("", &stripe.Backends{
    API:     backend,
    Connect: backend,
    Uploads: backend,
})

这是可行的--但我想不出我该如何模仿才能真正赢得客户？我不想嘲笑client.API。接口代码：https://github.com/stripe/stripe-go/blob/9c5fd87e31fd4a072b4d92571d67437e329dc9db/customer/client.go#L23

还有别的人在做这个吗？:)

谢谢

我认为你错误地实现了这个接口。

我对github.com/stripe/stripe-go/v71 v71.27.0的认识

import (
    "bytes"
    "github.com/stretchr/testify/mock"
    "github.com/stripe/stripe-go/v71"
    "github.com/stripe/stripe-go/v71/form"
)

type Backend struct {
    mock.Mock
}

func (s *Backend) Call(method, path, key string, params stripe.ParamsContainer, v stripe.LastResponseSetter) error {
    args := s.Called(params)
    return args.Error(0)
}

func (s *Backend) CallRaw(method, path, key string, body *form.Values, params *stripe.Params, v stripe.LastResponseSetter) error {
    args := s.Called(params)
    return args.Error(0)
}

func (s *Backend) CallMultipart(method, path, key, boundary string, body *bytes.Buffer, params *stripe.Params, v stripe.LastResponseSetter) error {
    args := s.Called(params)
    return args.Error(0)
}

func (s *Backend) SetMaxNetworkRetries(maxNetworkRetries int64) {
    s.Called(maxNetworkRetries)
}

要实现mock，您必须使用指针作为目标func (s *Backend) SetMaxNetworkRetries(maxNetworkRetries int64){...}，而不是方法的复制目标(func (s Backend) SetMaxNetworkRetries(maxNetworkRetries int64){...})。

Аlso你必须严格遵循方法签名。
