enzyme - JavaScript Testing utilities for React

•    Javascript

---

Enzyme is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Components' output.Enzyme's API is meant to be intuitive and flexible by mimicking jQuery's API for DOM manipulation and traversal.

Jasmine-Matchers - A huge library of test matchers for Jasmine and Jest.

•    Javascript

---

A huge library of test matchers for a range of common use-cases, compatible with all versions of Jasmine and Jest. Custom Matchers make tests easier to read and produce relevant and useful messages when they fail.

jest-extended - Additional Jest matchers 🃏💪

•    Javascript

---

Jest is an amazing test runner and has some awesome assertion APIs built in by default. However there are times when having more specific matchers (assertions) would be far more convenient. If you've come here to help contribute - Thanks! Take a look at the contributing docs as a way of getting started.

jest-dom - :owl: Custom jest matchers to test the state of the DOM

•    Javascript

---

You want to use jest to write tests that assert various things about the state of a DOM. As part of that goal, you want to avoid all the repetitive patterns that arise in doing so. Checking for an element's attributes, its text content, its css classes, you name it. The @testing-library/jest-dom library provides a set of custom jest matchers that you can use to extend jest. These will make your tests more declarative, clear to read and to maintain.

react-testing-mocha-jsdom - Unit testing React Components with Mocha + jsdom

•    Javascript

---

This is Part 2 of the series "Modular Isomorphic React JS applications". See Part 1 and Part 3 for more. Unit testing React is traditionally done using Jest which dictates the use of the Jasmine testing framework, and enforces mocking of all require calls. For such an unopinionated rendering engine, this is a very opinionated setup, resulting in issues such as overly-verbose unmocking of requires, and being tied into Jasmine's limited framework.

js-must - An assertion library for JavaScript and Node

•    Javascript

---

Must.js is a testing and assertion library for JavaScript and Node.js with a friendly BDD syntax (awesome.must.be.true()). It ships with many expressive matchers and is test runner and framework agnostic. Follows RFC 2119 with its use of MUST. Good and well testsed stuff. For those new to testing JavaScript on Node.js, you'll also need a test framework (also called a test-runner or a harness) to run your tests. One such tool is Mocha.

Ava - Futuristic JavaScript test runner

•    Javascript

---

AVA is a test runner for Node.js with a concise API, detailed error output, embrace of new language features and process isolation that lets you develop with confidence. AVA automatically detects whether your CI environment supports parallel builds. Each build will run a subset of all test files, while still making sure all tests get executed. It automatically removes unrelated lines in stack traces, allowing you to find the source of an error much faster.

teaspoon - A jQuery like API for testing React elements and rendered components.

•    Javascript

---

Just the right amount of abstraction for writing clear, and concise React component tests. Teaspoon is test environment agnostic, so you can (and should) bring your own test runner and frameworks. If you plan on doing normal component rendering (not just shallow rendering) you will also need a DOM environment, whether that's a browser, headless browser, or jsdom.

quixote - CSS unit and integration testing

•    Javascript

---

Quixote is a library for testing CSS. It's fast—over 100 tests/second—and has a powerful API. You can use it for unit testing (test your CSS files directly) or integration testing (test against a real server). Either way, your tests check how HTML elements are actually rendered by the browser. Quixote runs in the browser and works with any test framework. You can even test multiple browsers simultaneously by using a tool such as Karma or Test'em. It works in modern desktop browsers, mobile browsers, and IE 8+.

doctest - The fastest feature-rich C++11 single-header testing framework for unit tests and TDD

•    C++

---

doctest is a new C++ testing framework but is by far the fastest both in compile times (by orders of magnitude) and runtime compared to other feature-rich alternatives. It brings the ability of compiled languages such as D / Rust / Nim to have tests written directly in the production code by providing a fast, transparent and flexible test runner with a clean interface. The framework is and will stay free but needs your support to sustain its development. There are lots of new features and maintenance to do. If you work for a company using doctest or have the means to do so, please consider financial support. Monthly donations via Patreon and one-offs via PayPal.
