Testing

Tests are written in a BDD/Cucumber type syntax using mocha-cakes-2. Try to write tests in a meaningful way as to describe what it is you're testing and what resources are available. Testing does not only test a piece of code that it actually works but is also used for documentation purposes. Focus on testing what is vital for the feature.

To run all tests (including linting)...

$ npm test
