Go library for short-cutting HTTP clients to HTTP handlers

Your client code uses an http.Client. Your server code contains an http.Handler.

This package implements an http.RoundTripper that allows a HTTP client to call a HTTP handler directly without starting a HTTP server.

mux := http.NewServeMux()
mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "Hello world")
}

client := &http.Client{
    Transport: Transport{
        Handler: mux,
    },
}

resp, err := client.Get("http://example.com")

There is also a helper function to create a http.Client from a handler:

mux := http.NewServeMux()
mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "Hello world")
}

client := Client(nil, mux)

resp, err := client.Get("http://example.com")
