      What is Chai?

      It is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework. It has several interfaces that allow the developer to choose the most comfortable. The chain-capable BDD styles provide an expressive language & readable style, while the TDD assert style provides a more classical feel.

      What is Jest?

      Jest provides you with multiple layers on top of Jasmine.

      What is SinonJS?

      It is a really helpful library when you want to unit test your code. It supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.
