# Wabbit - Go AMQP Mocking Library

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](https://github.com/streadway/amqp) (a
wrapper).
What are the advantages of this?
### Usage
[How to use ?](/_examples)
### Testing
This package have an AMQP interface and two possible implementations:
- wabbit/amqp - Bypass to [streadway/amqp](https://github.com/streadway/amqp)
- 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:
```go
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:
```go
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.
