karma-jasmine-matchers

karma-jasmine-matchers

A Karma plugin to inject Jasmine-Matchers for Jasmine.

1. Make failing tests easier to debug by avoiding vague messages such as "expected false to be true" in favour of useful cues such as "expected 3 to be even number".
2. Make tests easier to read by avoiding implementation noise such as expect(cycleWheels % 2 === 0).toEqual(true) in favour of simply stating that you expect(cycleWheels).toBeEvenNumber().
