Mocha Alternatives & Comparisons

What are some alternatives to Mocha?

Jest provides you with multiple layers on top of Jasmine.
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.
Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested.
