Chai vs Venus.js: What are the differences?

Developers describe Chai as "A BDD / TDD assertion library". 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. On the other hand, Venus.js is detailed as "*Where bugs go to die *". It is a testing tool for JavaScript (JS), which simplifies running unit tests. When you are developing a browser-based project in JS, you'll want to create unit tests and run them frequently. Typically, you'll write a unit test using some library, such as Mocha or Jasmine. These libraries let you define testcases (or "specs" if you are following a BDD style), and provide APIs for writing assertions.

Chai and Venus.js can be categorized as "Javascript Testing Framework" tools.
