## README

# simple-assert [![Build Status](https://travis-ci.org/chaijs/simple-assert.png?branch=master)](https://travis-ci.org/chaijs/simple-assert)

> Vanilla Assertions

A simple `assert` wrapper around [chaijs/assertion-error](https://github.com/chaijs/assertion-error). This probably
won't be useful to the average user unless you are a minimalist; you probably want [Chai](https://github.com/chaijs/chai).
We use it to avoid circular dependencies when testing Chai's dependencies.
