xv-tom-l / go-httpbin

http://httpbin.org endpoints for your Go tests –

go-httpbin

A Go handler that lets you test your HTTP client, retry logic, streaming behavior, timeouts etc. with the endpoints of httpbin.org locally in a net/http/httptest.Server.

This way, you can write tests without relying on an external dependency like httpbin.org.

Endpoints

• /ip Returns Origin IP.
• /user-agent Returns user-agent.
• /headers Returns headers.
• /get Returns GET data.
• /status/:code Returns given HTTP Status code.
• /redirect/:n 302 Redirects n times.
• /absolute-redirect/:n 302 Absolute redirects n times.
• /redirect-to?url=foo 302 Redirects to the foo URL.
• /stream/:n Streams n lines of JSON objects
• /delay/:n Delays responding for min(n, 10) seconds.
• /bytes/:n Generates n random bytes of binary data, accepts optional seed integer parameter.
• /cookies Returns the cookies.
• /cookies/set?name=value Sets one or more simple cookies.
• /cookies/delete?name Deletes one or more simple cookies.
• /drip?numbytes=n&duration=s&delay=s&code=code Drips data over a duration after an optional initial delay, then optionally returns with the given status code.
• /cache Returns 200 unless an If-Modified-Since or If-None-Match header is provided, when it returns a 304.
• /cache/:n Sets a Cache-Control header for n seconds.

How to use

Standing up a Go server running httpbin endpoints is just 1 line:

package main

import (
    "log"
    "net/http"
    "github.com/ahmetalpbalkan/go-httpbin"
)

func main() {
	log.Fatal(http.ListenAndServe(":8080", httpbin.GetMux()))
}

Let's say you do not want a server running all the time because you just want to test your HTTP logic after all. Integrating httpbin to your tests is very simple:

package test

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

    "github.com/ahmetalpbalkan/go-httpbin"
)

func TestDownload(t *testing.T) {
    srv := httptest.NewServer(httpbin.GetMux())
    defer srv.Close()

    resp, err := http.Get(srv.URL + "/bytes/65536")
    if err != nil {
        t.Fatal(err)
    }
    // read from an actual HTTP server hosted locally
    // test whatever you are going to test...
}
