# AMQP
### Installation
If you use Codeception installed using composer, install this module with the following command:
{% highlight yaml %}
composer require --dev codeception/module-amqp
{% endhighlight %}
Alternatively, you can enable `AMQP` module in suite configuration file and run
{% highlight yaml %}
codecept init upgrade4
{% endhighlight %}
This module was bundled with Codeception 2 and 3, but since version 4 it is necessary to install it separately.
Some modules are bundled with PHAR files.
Warning. Using PHAR file and composer in the same project can cause unexpected errors.
### Description
This module interacts with message broker software that implements
the Advanced Message Queuing Protocol (AMQP) standard. For example, RabbitMQ (tested).
To use this module with Composer you need "php-amqplib/php-amqplib": "~2.4" package.
### Config
* host: localhost - host to connect
* username: guest - username to connect
* password: guest - password to connect
* vhost: '/' - vhost to connect
* cleanup: true - defined queues will be purged before running every test.
* queues: [mail, twitter] - queues to cleanup
* single_channel - create and use only one channel during test execution

- AMQP:
host: 'localhost'
port: '5672'
