Golang HTTP 超时测试，未按预期超时

Question

I built a small testcase, that checks that code on my end timesout after a set amount of time has passed. But this isnt working as expected

I am hitting an server sided endpoint which works fine, but what happens if it is slower than usual, I will need code on my end to timeout, this has been implemented but I need to test that I implemented it correctly.

This is what I have so far

func TestTimeout(t *testing.T) {
ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
    time.Sleep(time.Second * 15)
}))
defer ts.Close()
client := &http.Client{
    Timeout: time.Second * 10,
}
myRequest,err := createMyRequest(Somedata,SomeMoreData)
res, err := client.Do(myRequest)
if err != nil {
    t.Fatal(err)
}
res.Body.Close()}

However my code successfully runs without giving a timeout error (as in I am not waiting for 10 seconds, where am I going wrong?

As already pointed out in some of the comments, you need to make a request to the test server's endpoint (using ts.URL ) as follows:

myRequest, err := http.NewRequest(http.MethodPost, ts.URL, bytes.NewBuffer([]byte("test")))
if err != nil {
    t.Fatal(err)
}
res, err := client.Do(myRequest)
if err != nil {
    t.Fatal(err)
}
