如何在Go中编写一个作为方法的测试？

How to write a test as a method in Go?

问题

我有一个以下的测试：

  1. package api_app
  3. func (api *ApiResource) TestAuthenticate(t *testing.T) {
  4.     httpReq, _ := http.NewRequest("POST", "/login", nil)
  5.     req := restful.NewRequest(httpReq)
  7.     recorder := new(httptest.ResponseRecorder)
  8.     resp := restful.NewResponse(recorder)
  10.     api.Authenticate(req, resp)
  11.     if recorder.Code != 404 {
  12.         t.Logf("Missing or wrong status code:%d", recorder.Code)
  13.     }
  14. }

我想测试这个函数，但是当我运行go test api_app -v时，测试从来没有运行过。我理解这是因为我为这个函数定义了接收器。

有没有办法我们可以测试这个东西？

英文:

I have a below test:

  1. package api_app
  3. func (api *ApiResource) TestAuthenticate(t *testing.T) {
  4. 	httpReq, _ := http.NewRequest("POST", "/login", nil)
  5. 	req := restful.NewRequest(httpReq)
  7. 	recorder := new(httptest.ResponseRecorder)
  8. 	resp := restful.NewResponse(recorder)
  10. 	api.Authenticate(req, resp)
  11. 	if recorder.Code!= 404 {
  12. 		t.Logf("Missing or wrong status code:%d", recorder.Code)
  13. 	}
  14. }

I want to test this function but when I do

go test api_app -v

The test never rungs this. I understand that's because I have receiver for the function.

Is there a way we can test this thing?

测试包 适用于函数，而不是方法。编写一个函数包装器来测试该方法：

  1. func TestAuthenticate(t *testing.T) {
  2.    api := &ApiResource{} // <-- 根据需要初始化 api。
  3.    api.TestAuthenticate(t)
  4. }

你可以将所有代码移到测试函数中并消除该方法：

  1. func TestAuthenticate(t *testing.T) {
  2.     api := &ApiResource{} // <-- 根据需要初始化 api。
  3.     httpReq, _ := http.NewRequest("POST", "/login", nil)
  4.     req := restful.NewRequest(httpReq)
  6.     recorder := new(httptest.ResponseRecorder)
  7.     resp := restful.NewResponse(recorder)
  9.     api.Authenticate(req, resp)
  10.     if recorder.Code != 404 {
  11.         t.Logf("缺少或错误的状态码：%d", recorder.Code)
  12.     }
  13. }
英文:

The testing package works with functions, not methods. Write a function wrapper to test the method:

  1. func TestAuthenticate(t *testing.T) {
  2.    api := &amp;ApiResource{} // &lt;-- initialize api as appropriate.
  3.    api.TestAuthenticate(t)
  4. }

You can move all of the code to the test function and eliminate the method:

  1. func TestAuthenticate(t *testing.T) {
  2.     api := &amp;ApiResource{} // &lt;-- initialize api as appropriate.
  3. 	httpReq, _ := http.NewRequest(&quot;POST&quot;, &quot;/login&quot;, nil)
  4. 	req := restful.NewRequest(httpReq)
  6. 	recorder := new(httptest.ResponseRecorder)
  7. 	resp := restful.NewResponse(recorder)
  9. 	api.Authenticate(req, resp)
  10. 	if recorder.Code!= 404 {
  11. 		t.Logf(&quot;Missing or wrong status code:%d&quot;, recorder.Code)
  12. 	}
  13. }
