What it is

Nightwatch is a free, open-source Node.js framework for automated testing of websites and web applications. It supports end-to-end browser tests, Node.js service unit tests, and HTTP API integration tests. Its command-line interface has built-in support for Chrome, Firefox, Safari, and Edge; Appium supports functional tests on native iOS and Android apps. A visual regression plugin captures screenshots and compares them with baselines, while component testing covers React, Vue, Angular, and Storybook. An axe-core plugin provides 90 types of accessibility tests for WCAG compliance. The built-in HTML report shows environment and test details, and DOM History allows inspection of elements at each test step. Nightwatch also supports parallel execution and names integrations for distributed testing, including Selenium Grid, BrowserStack, Sauce Labs, CrossBrowserTesting, LambdaTest, and TestingBot. It is licensed under MIT and described as actively maintained by BrowserStack’s Open Source Program. The listed plan is free, with no paywalls.
