AVA vs Chai: What are the differences?

AVA: A refined, futuristic test runner. Even though JavaScript is single-threaded, IO in Node.js can happen in parallel due to its async nature. AVA takes advantage of this and runs your tests concurrently, which is especially beneficial for IO heavy tests. In addition, test files are run in parallel as separate processes, giving you even better performance and an isolated environment for each test file; Chai: 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.

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

AVA and Chai are both open source tools. AVA with 16.5K GitHub stars and 1.08K forks on GitHub appears to be more popular than Chai with 6.39K GitHub stars and 575 GitHub forks.

Taboola, Becual.com, and Navendis are some of the popular companies that use AVA, whereas Chai is used by BeatSense, Brainhub, and Clovis. AVA has a broader approval, being mentioned in 12 company stacks & 11 developers stacks; compared to Chai, which is listed in 6 company stacks and 8 developer stacks.

What are some alternatives to Chai, AVA?

Mocha

Mocha

Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.

Jasmine

Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.

Jest

Jest

Jest provides you with multiple layers on top of Jasmine.

Cypress

Cypress

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. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.

CodeceptJS

CodeceptJS

It is a modern end to end testing framework with a special BDD-style syntax. The test is written as a linear scenario of user's action on a site. Each test is described inside a Scenario function with I object passed into it.

Protractor

Protractor

Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.

Ghost Inspector

It lets you create and manage UI tests that check specific functionality in your website or application. We execute these automated browser tests continuously from the cloud and alert you if anything breaks.

QUnit

QUnit

QUnit is a powerful, easy-to-use JavaScript unit testing framework. It's used by the jQuery, jQuery UI and jQuery Mobile projects and is capable of testing any generic JavaScript code, including itself!

Sorry-cypress

Sorry-cypress
