A very simple Test Helper, framework independent.
Dexter is a Test Helper. With Dexter, you can spy functions and create stubs to prevent their default functionality and set callbacks to create your assertions.
It's like Sinon.JS, but this is VERY simple. The goal is to keep it simple and clean.
DexterJS wouldn´t be possible without all the support from Estante Virtual (pt_BR).
Special thanks to Rick Waldron for doing the first code review.
