Bunny Mock
==========
[](https://travis-ci.org/arempe93/bunny-mock)
[](https://rubygems.org/gems/bunny-mock)
[](https://coveralls.io/github/arempe93/bunny-mock?branch=master)
[](http://www.rubydoc.info/github/arempe93/bunny-mock)
A mock client for RabbitMQ, modeled after the popular [Bunny client](https://github.com/ruby-amqp/bunny). It currently supports basic usage of Bunny for managing exchanges and queues, with the goal of being able to handle and test all Bunny use cases.
##### Upgrading
This project does its best to follow [semantic versioning practices](http://semver.org/). Check the [CHANGELOG](CHANGELOG.md) to see detailed versioning notes, and [UPGRADING](UPGRADING.md) for notes about major changes or deprecations.
## Usage
BunnyMock can be injected into your RabbitMQ application in place of Bunny for testing. For example, if you have a helper module named `AMQFactory`, some code similar to the following placed in `spec_helper` or `test_helper` or what have you is all you need to start using BunnyMock to test your RabbitMQ application
```ruby
require 'bunny-mock'
RSpec.configure do |config|
config.before(:each) do
AMQFactory.connection = BunnyMock.new.start
end
end
```
For an example, easy to mock setup, check out [this helper](https://gist.github.com/arempe93/8143edb17c57666e738f)
## Examples
Here are some examples showcasing what BunnyMock can do
#### Declaration
```ruby
it 'should create queues and exchanges' do
session = BunnyMock.new.start
channel = session.channel
queue = channel.queue 'queue.test'
expect(session.queue_exists?('queue.test')).to be_truthy
queue.delete
expect(session.queue_exists?('queue.test')).to be_falsey
xchg = channel.exchange 'xchg.test'
expect(session.exchange_exists?('xchg.test')).to be_truthy
xchg.delete
expect(session.exchange_exists?('xchg.test')).to be_falsey
end
```
#### Publishing
```ruby
it 'should publish messages to queues' do
channel = BunnyMock.new.start.channel
queue = channel.queue 'queue.test'
queue.publish 'Testing message', priority: 5
expect(queue.message_count).to eq(1)
payload = queue.pop
expect(queue.message_count).to eq(0)
expect(payload[:message]).to eq('Testing message')
expect(payload[:options][:priority]).to eq(5)
end
it 'should route messages from exchanges' do
channel = BunnyMock.new.start.channel
xchg = channel.topic 'xchg.topic'
queue = channel.queue 'queue.test'
queue.bind xchg, routing_key: '*.test'
xchg.publish 'Routed message', routing_key: 'foo.test'
expect(queue.message_count).to eq(1)
expect(queue.pop[:message]).to eq('Routed message')
end
```
#### Binding
```ruby
it 'should bind queues to exchanges' do
channel = BunnyMock.new.start.channel
queue = channel.queue 'queue.test'
xchg = channel.exchange 'xchg.test'
queue.bind xchg
expect(queue.bound_to?(xchg)).to be_truthy
expect(xchg.routes_to?(queue)).to be_truthy
queue.unbind xchg
expect(queue.bound_to?(xchg)).to be_falsey
expect(xchg.routes_to?(queue)).to be_falsey
queue.bind 'xchg.test'
expect(queue.bound_to?(xchg)).to be_truthy
expect(xchg.routes_to?(queue)).to be_truthy
end
it 'should bind exchanges to exchanges' do
channel = BunnyMock.new.start.channel
source = channel.exchange 'xchg.source'
receiver = channel.exchange 'xchg.receiver'
receiver.bind source
expect(receiver.bound_to?(source)).to be_truthy
expect(source.routes_to?(receiver)).to be_truthy
receiver.unbind source
expect(receiver.bound_to?(source)).to be_falsey
expect(source.routes_to?(receiver)).to be_falsey
receiver.bind 'xchg.source'
expect(receiver.bound_to?(source)).to be_truthy
expect(source.routes_to?(receiver)).to be_truthy
end
```
## Other features
This gem was made based on my own use of Bunny in a project. If there are other uses for Bunny that this library does not cover (eg. missing methods, functionality), feel free to open an issue or pull request!
