http.Client mocking when you can't control the URL

Install

go get gopkg.in/nowk/go-netmock.v0

Example

You use a http.DefaultClient mapped interface.

type SomeApi struct {
  HTTPClient HTTPClient
}

func (s SomeApi) GetSomeApiRequest() (*http.Response, error) {
  return s.HTTPClient.Get("http://example.com")
}

Pass your mock in your tests.

func TestRequest(t *testing.T) {
  mock := netmock.NewMock(t)
  mock.Expect("GET", "http://example.com").Respond(200, "Hello World!")

  api := &SomeApi{mock.HTTPClient}
  res, _ := api.GetSomeApiRequest()

  if code := res.StatusCode; code != 200 {
    t.Errorf("Expected 200, got %d", code)
  }
}

Register routes

mock.Expect("GET", "http://example.com").Respond(200, "Hello World!")

With a regexp

reg := regexp.MustCompile(`http:\/\/example\.com\/foo`)
mock.Expect("GET", reg).Respond(200, "Hello World!")

Modify the response

res, _ := mock.Expect("GET", "http://example.com").Respond(200, `{"foo": "bar"}`)
res.Header.Add("Content-Type", "application/json")

Spy on the Request

_, mr := mock.Expect("GET", "http://example.com").Respond(200, "Hello World!")

Number of times called

mr.Called(1).Times()

Request Body

mr.Body().Equals("Hello World!")

Request Header

mr.Header("Content-Type").Equals("application/json")

Form values

mr.Form("foo").Equals("bar")

PostForm values

mr.PostForm("baz").Equals("qux")
