Next‑gen Node.js framework for browser and mobile test automation
WebdriverIO enables end‑to‑end, unit, and component testing across browsers and mobile devices using WebDriver, BiDi, and Appium, with seamless integration to popular BDD/TDD frameworks and cloud providers.
WebdriverIO is a versatile test automation framework for Node.js that supports end‑to‑end, unit, and component testing in both web browsers and mobile applications. It abstracts the WebDriver, WebDriver BiDi, and Appium protocols behind a unified API, allowing developers to write tests once and run them across a wide range of environments.
The framework integrates with leading BDD/TDD libraries such as Mocha, Jasmine, and Cucumber, and provides a powerful CLI, configuration parser, and test runner. Tests can be executed locally or on cloud platforms like Sauce Labs, BrowserStack, TestingBot, and LambdaTest. An extensive ecosystem of services, reporters, and plugins—covering everything from Appium server management to Lighthouse audits—enables teams to tailor the workflow to their CI/CD pipelines. Commercial support is available through a Tidelift subscription for enterprises seeking guaranteed maintenance and risk mitigation.
When teams consider WebdriverIO, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Cross‑browser regression testing
Validate UI consistency across Chrome, Firefox, Safari, and Edge on every release.
Mobile app end‑to‑end flow
Automate user journeys on iOS and Android devices using Appium.
Component testing in the browser
Run isolated UI component tests with Mocha or Jest directly in the browser.
CI integration
Execute tests on pull requests via GitHub Actions and cloud providers like Sauce Labs.
Any browser implementing the W3C WebDriver protocol, including Chrome, Firefox, Safari, and Edge.
Yes, through the Appium service it can automate iOS and Android devices, both simulators and physical hardware.
WebdriverIO works with Mocha, Jasmine, and Cucumber out of the box, and can be extended to others.
Enterprises can obtain commercial support and maintenance via a Tidelift subscription.
Use built‑in services for Sauce Labs, BrowserStack, TestingBot, or LambdaTest to run tests on their grids.
