TL;DR

• If you want to “just get started” or looking for a fast framework for large projects, go with Jest.
• If you want a very flexible and extendable configuration, go with Mocha.
• If you are looking for simplicity go with Ava.
• If you want to be really low-level, go with tape.

Test framework/library

• Mocha - the fun, simple, flexible JavaScript test framework.
• Jest - Delightful JavaScript Testing.
• tape - npm - tap-producing test harness for node and browsers.
• tape-promise - Promise and ES2016 (ES7)async/awaitsupport for- Tape.
• supertest: Super-agent driven library for testing node.js HTTP servers using a fluent API.

Assertion library

• Chai - có thể sử dụng tất cả các phong cách test expect/should/assert.
• chai-as-promised - npm
• expect - npm - expect này chính là function expect được export từ trong Jest của Facebook.
• should - npm - ít dùng hơn expect.

Mock tools

• node-mocks-http- Mock ‘http’ objects for testing Express routing functions.
• Sinon.JS - Standalone test fakes, spies, stubs and mocks for JavaScript. Works with any unit testing framework.
• nock : HTTP server mocking and expectations library for Node.js
• faker.js : generate massive amounts of realistic fake data in Node.js and the browser

ESlint plugin

• eslint-plugin-chai-expect - npm - discover test without assertions
• eslint-plugin-mocha - npm - eslint rules for mocha
• eslint-plugin-jest - npm - eslint rules for jest
• eslint-plugin-promise - npm - discover promises with no resolve
• eslint-plugin-security - npm - discover eager regex expression that might get used for DOS attack

property-based testing

• JSVerify - property based testing for JavaScript. Like QuickCheck.
• TestCheck.js - Generative property testing for JavaScript.
• fast-check - Property based testing framework for JavaScript (like QuickCheck) written in TypeScript.

analysis code

• SonarQube - Continuous Inspection, Continuous Code Quality.
• Code Climate - process insights and automated code review.

Node-related chaos

• chaosmonkey - Chaos Monkey is a resiliency tool that helps applications tolerate random instance failures.
• kube-monkey - An implementation of Netflix’s Chaos Monkey for Kubernetes clusters.

mutation testing

• Stryker Mutator - Test your tests with mutation testing.

License check

• license-checker - npm

audit dependencies

• Auditing package dependencies for security vulnerabilities
• Snyk - automates finding & fixing vulnerabilities in your dependencies.
