How to test http calls in Go using httptest

Question

I have the following code:

package main

import (
    \"encoding/json\"
    \"fmt\"
    \"io/ioutil\"
    \"log\"
    \"net/http\"
    \"time\"
)

type twitt         


        

Answer 1

If you want to test your program, it is often best to write it with testing in mind. For instance, if you extracted the inner loop of your retrieveTweets function into something like this:

func downloadTweets(tweetsUrl string) (*twitterResult, error)

You could invoke it with the URL of a test server you've set up using the httptest package without having to worry about the sleeps or repeated requests.
