如何在 Go 中将测试编写为方法？

Question

我有以下测试：

package api_app

func (api *ApiResource) TestAuthenticate(t *testing.T) {

    httpReq, _ := http.NewRequest("POST", "/login", nil)

    req := restful.NewRequest(httpReq)

    recorder := new(httptest.ResponseRecorder)

    resp := restful.NewResponse(recorder)

    api.Authenticate(req, resp)

    if recorder.Code!= 404 {

        t.Logf("Missing or wrong status code:%d", recorder.Code)

    }

}

我想测试这个功能，但是当我这样做的时候

go test api_app -v

测试从来没有这样。我明白那是因为我有这个功能的接收器。

有什么方法可以测试这个东西吗？

该测试包可与功能，而不是方法。编写一个函数包装器来测试该方法：func TestAuthenticate(t *testing.T) {&nbsp; &nbsp;api := &ApiResource{} // <-- initialize api as appropriate.&nbsp; &nbsp;api.TestAuthenticate(t)}您可以将所有代码移动到测试函数并消除该方法：func TestAuthenticate(t *testing.T) {&nbsp; &nbsp; api := &ApiResource{} // <-- initialize api as appropriate.&nbsp; &nbsp; httpReq, _ := http.NewRequest("POST", "/login", nil)&nbsp; &nbsp; req := restful.NewRequest(httpReq)&nbsp; &nbsp; recorder := new(httptest.ResponseRecorder)&nbsp; &nbsp; resp := restful.NewResponse(recorder)&nbsp; &nbsp; api.Authenticate(req, resp)&nbsp; &nbsp; if recorder.Code!= 404 {&nbsp; &nbsp; &nbsp; &nbsp; t.Logf("Missing or wrong status code:%d", recorder.Code)&nbsp; &nbsp; }}
