How can I use the httptest package in Go?

The httptest package in Go is used for testing HTTP servers and clients. You can create mock servers to test your handlers.

Can you show me a simple example of how to set it up?

Sure! Here's a basic example:

package main

import (
    "net/http"
    "net/http/httptest"
    "testing"
)

func TestMyHandler(t *testing.T) {
    req := httptest.NewRequest("GET", "http://example.com/foo", nil)
    w := httptest.NewRecorder()
    handler := http.HandlerFunc(MyHandler)

    handler.ServeHTTP(w, req)

    res := w.Result()
    // Check response status code, body, etc.
}

What should I check in the response?

You can check the status code, response body, headers, and any other relevant information to ensure your handler works as expected.
