Go Appengine端点测试的问题

I am trying to create an endpoint test when using appengine. Unfortunately, the tests keep failing because of the lack of a schema (and host) within the url used when creating the test *Request struct. When running appengine tests a server is spawned for that specific test that runs on a semi-random port number, which makes it seemingly impossible to define the full url to perform the test on.

The official docs on running tests like this are very sparse and only give half of an example, so I am left scratching my head on how to get this to work.

This is the error that I get from the marked line within the code snippet Error: Received unexpected error "Post /auth: unsupported protocol scheme \"\""

Test Code

func TestEndpoints_Auth(t *testing.T) {

    // input data
    account := Account{
        AuthProvider:   "facebook",
        AuthProviderId: "123345456",
    }
    b, _ := json.Marshal(&account)
    reader := bytes.NewReader(b)

    // test server
    inst, err := aetest.NewInstance(nil)
    if !assert.NoError(t, err) { return }
    defer inst.Close()

    // request
    client := http.Client{}
    req, err := inst.NewRequest("POST", "/auth", reader)
    if !assert.NoError(t, err) { return }
    req.Header.Add(AppAuthToken, "foobar")
    resp, err := client.Do(req)
    if !assert.NoError(t, err) { return }   // <=== Where the error occurs

    // tests
    if !assert.Nil(t, err) { return }
    assert.Equal(t, http.StatusCreated, resp.StatusCode)
}

I was really hoping to perform api blackbox tests, but that seems to be undoable with appengine. Instead I am now performing the tests on the endpoint directly.

req, _ := inst.NewRequest("POST", "/auth", reader)
req.Header.Add(AppAuthToken, "foobar")
resp := httptest.NewRecorder()

handlePostAuth(resp, req)
assert.Equal(t, http.StatusCreated, resp.Code)
