Introduction

AE is an assertions framework designed to serve as a reusable domain language for other test frameworks. It is light-weight, easy to use and versatile. The DSL is entirely focused around two methods #assert and #expect.

Features

• Clear, simple and concise syntax.
• Uses higher-order functions and fluid notation.
• Easily extensible allowing for alternate notations.
• Reusable core extensions ease assertion construction.
• Core extensions are standardized around Ruby Facets.
• Facets is not a dependency; the extensions are built-in.
• Eats it's own dog food.

Adaptations

AE is the standard assertions framework for QED and Lemon; works with Test::Unit, MiniTest and Shoulda; and is easily adapted to almost any other testing framework.
