Leo allows you to make assertions in PHP with an easy to read API. It supports a BDD style expect interface, and an object oriented assert interface.
Leo is also highly extensible. It's a snap to add additional functionality. You can create a language that suits your needs best. See the plugin guide to get started.

Usage
You can install Leo via composer:
composer require peridot-php/leo:~1.0
The expect interface is leveraged via the global function expect.
<?php
expect($actual)->to->equal($expected);
?>
The assert interface can be used via the Assert class.
<?php
use Peridot\Leo\Interfaces\Assert;
$assert = new Assert();
$assert->ok(true);
?>
