I have something that looks like so:
func (client *MyCustomClient) CheckURL(url string, json_response *MyCustomResponseStruct) bool {
r, err = http.Get(url)
if err != nil {
return false
}
defer r.Body.Close()
.... do stuff with json_response
And in my test, I have the following:
func TestCheckURL(t *test.T) {
ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/html; charset=UTF-8")
fmt.Fprintln(w, `{"status": "success"}`)
}))
defer ts.Close()
json_response := new(MyCustomResponseStruct)
client := NewMyCustomClient() // returns instance of MyCustomClient
done := client.CheckURL("test.com", json_response)
However, it does not appear as if the HTTP test server is working and that it actually goes out to test.com, as evidenced by the log output:
Get http:/test.com: dial tcp X.Y.Z.A: i/o timeout
My question is how to properly use the httptest package to mock out this request... I read through the docs and this helpful SO Answer but I'm still stuck.
Your client only calls the URL you provided as the first argument to the CheckURL method. Give your client the URL of your test server:
done := client.CheckURL(ts.URL, json_response)
