 **Test.it** is a small testing library for people that want to live in code, not in tests.  No over engineering here.  Inspired by the simplicity of libraries like [Tape](https://github.com/substack/tape),but the implementation ideas of things like [Expect](https://github.com/Automattic/expect.js) and [TinyTest](https://github.com/joewalnes/jstinytest)

+A `+OK` will proceed test lines that *pass* and a `-ERR` for those that *fail*, An error stack is included by default after the failing test wrapped in `---`.  You can suppress outputing the error stack by passing `false` as an argument to `run()`, ie `run(false)`.
 
 You can, however, write your own custom test runner...

 From this object you can easily find the number of tests ran `pass.length`, number of failed tests `fail.length` or the total test count by adding the two.  Simple.
 
+> REMEMBER: you can bypass error output too

 A sample test runner is provided for both **HTML** and **NODE** in the `test/` directory; `run.html` and `run.js` respectfully.
