Its core goal is to offer a test double framework with a succint API capable of clearly defining all possible object operations and interactions using a human readable Domain Specific Language (DSL). Designed as a drop in alternative to PHPUnit's phpunit-mock-objects library, Mockery is easy to integrate with PHPUnit and can operate alongside phpunit-mock-objects without the World ending.",
