Unit testing

Automated tests are an important part of software development today. Providing a standard test library will help encourage more people to write more tests. Additionally, the API specification will likely be written in the form of tests, so this component will be needed by the ServerJS project itself.

Testing involves both an API for easily defining tests and running assertions, plus a tool (or tools) for locating and running the tests.
