# Test Runners

• 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 is used by Facebook to test all JavaScript code including React applications.
  • Majestic - Zero config GUI for Jest
  • Mastering Jest
• Lab is a simple test utility for node.
• Mocha is a feature-rich JavaScript test framework running on Node.js and the browser, making asynchronous testing simple and fun.
• Tape tap-producing test harness for node and browsers
• uvu - is an extremely fast and lightweight test runner for Node.js and the browser.
• Intern
• DalekJS Cross-browser testing

# E2E

• Cypress - Fast, easy and reliable testing for anything that runs in a browser.
• Nightwatch is an easy to use Node.js based End-to-End (E2E) testing solution for browser based apps and websites
• Protractor is an end-to-end test framework for AngularJS applications.

# Libraries

• Chai.js Assertion library supporting expect, should and assert styles.
• expect.js - Assertion library supporting expect syntax
• frisby.js - HTTP calls and assertions using Jest for running tests
• Polly.js - Record, replay, and stub HTTP interactions.
• Should.js - Assertion library supporting should syntax
• TAIKO - an open source node.js library for testing modern web applications

Jasmine uses a built-in version of the expect styles.
