Elmer Fudd: Shhh. Be vewy vewy quiet, I'm hunting wabbits

AMQP is a verbose protocol that makes it difficult to implement proper unit-testing on your application. The first goal of this package is provide a sane interface for an AMQP client implementation based on the specification AMQP-0-9-1 (no extension) and then an implementation of this interface using the well established package streadway/amqp (a wrapper).

What are the advantages of this?

How to use ?

This package have an AMQP interface and two possible implementations:

• wabbit/amqp - Bypass to rabbitmq/amqp091-go
• wabbit/amqptest

In the same way you can use the http package in your software and use the httptest for testing, when using wabbit is recommended to use the wabbit/amqp package on your software and wabbit/amqptest in your tests. Simple test example:

package main

import (
	"testing"
	"github.com/NeowayLabs/wabbit/amqptest"
	"github.com/NeowayLabs/wabbit/amqptest/server"
	"github.com/NeowayLabs/wabbit/amqp"
)


func TestChannelCreation(t *testing.T) {
	mockConn, err := amqptest.Dial("amqp://localhost:5672/%2f") // will fail,

	if err == nil {
		t.Error("This shall fail, because no fake amqp server is running...")
	}

	fakeServer := server.NewServer("amqp://localhost:5672/%2f")
	fakeServer.Start()

	mockConn, err = amqptest.Dial("amqp://localhost:5672/%2f") // now it works =D

	if err != nil {
		t.Error(err)
	}

	//Now you can use mockConn as a real amqp connection.
	channel, err := mockConn.Channel()

    // ...
}

The package amqptest/server implements a mock AMQP server and it can be used to simulate network partitions or broker crashs. To create a new server instance use server.NewServer passing any amqpuri. You can create more than one server, but they need to have different amqpuris. Example below:

    broker1 := server.NewServer("amqp://localhost:5672/%2f")
    broker2 := server.NewServer("amqp://192.168.10.165:5672/%2f")
    broker3 := server.NewServer("amqp://192.168.10.169:5672/%2f")

    broker1.Start()
    broker2.Start()
    broker3.Start()

Calling NewServer with same amqpuri will return the same server instance.

Use broker.Stop() to abruptly stop the amqp server.

There's no fake clustering support yet (maybe never)

It's a very straightforward implementation that need a lot of improvements yet. Take careful when using it.
