This repository also contains a demo app with some tests (more in next release).
Please setup environment as explained before you start.
Tests you can find in 'tests' folder in Demoapp. If you a novice in UnitTests, I suggest you read about ideology of UnitTest-driven development and then learn Jasmine API: http://pivotal.github.com/jasmine/
Developing a UnitTest is not a hard task. Tests should be clear and simple.
After the tests are ready and index file in tests folder is configured - you can simply run testall.sh from console in 'tools' folder. JSLint errors and Jasmine output will be in 'logs' folder.
