testflight

Build Status

Installation

go get github.com/drewolson/testflight
import "github.com/drewolson/testflight"

Usage

testflight makes it simple to test your http servers in Go. Suppose you're using pat to create a simple http handler, like so:

func Handler() http.Handler {
	m := pat.New()

	m.Get("/hello/:name", http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) {
		io.WriteString(w, "hello, "+req.URL.Query().Get(":name"))
	}))

	m.Post("/post/form", http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) {
		req.ParseForm()
		name := req.Form.Get("name")
		w.WriteHeader(201)
		io.WriteString(w, name+" created")
	}))

	return m
}

Let's use testflight to test our handler. Keep in mind that testflight is doing full-stack http tests. We're also using assert for test assertions.

func TestGet(t *testing.T) {
	testflight.WithServer(Handler(), func(r *testflight.Requester) {
		response := r.Get("/hello/drew")

		assert.Equal(t, 200, response.StatusCode)
		assert.Equal(t, "hello, drew", response.Body)
	})
}

func TestPostWithForm(t *testing.T) {
	testflight.WithServer(Handler(), func(r *testflight.Requester) {
		response := r.Post("/post/form", testflight.FORM_ENCODED, "name=Drew")

		assert.Equal(t, 201, response.StatusCode)
		assert.Equal(t, "Drew created", response.Body)
	})
}

The testflight.Requester struct has the following methods: Get, Post, Put, Delete and Do. Do accepts an *http.Request for times when you need more explicit control of your request. See testflight_test.go for more usage information.

Testing Websockets

Testflight also allows you to perform full-stack testing of websockets. You'll want to import both the testflight and testflight/ws packages.

import (
    "github.com/drewolson/testflight"
    "github.com/drewolson/testflight/ws"
)

Now, let's make a handler with a websocket route.

func Handler() http.Handler {
	mux := http.NewServeMux()

	mux.Handle("/websocket", websocket.Handler(func(ws *websocket.Conn) {
		var name string
		websocket.Message.Receive(ws, &name)
		websocket.Message.Send(ws, "Hello, "+name)
	}))

	return mux
}

Finally, let's write the test.

func TestWebSocket(t *testing.T) {
    testflight.WithServer(Handler(), func(r *testflight.Requester) {
        connection := ws.Connect(r, "/websocket")

        connection.SendMessage("Drew")
        message, _ := connection.ReceiveMessage()
        assert.Equal(t, "Hello, Drew", message)
    })
}
