模拟 API 时如何保证请求正确发生？

Question

假设我正在测试一个调用 Web 服务的功能，并且该服务被模拟为httptest.NewServer

func TestSomeFeature(t *testing.T) {

    server := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {

        w.WriteHeader(200)

    }))

    SomeFeature(server.URL, "foo")

}

func SomeFeature(host, a string) {

    if a == "foo" {

        http.Get(fmt.Sprintf("%v/foo", host))

    }

    if a == "bar" {

        http.Get(fmt.Sprintf("%v/bar", host))

    }

}

如何断言服务器是使用正确的 url 调用的，/foo如果使用错误的 url 调用或根本没有调用它，则测试失败？

你可以这样做：func TestSomeFeature(t *testing.T) {    called := false    server := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {        // assert that strings.Contains(r.RequestURI, "/foo") is true        called = true        w.WriteHeader(200)    }))    SomeFeature(server.URL, "foo")    // assert that called is true}
