Taiko

What Taiko is

Taiko is a free, MIT-licensed, open source Node.js library for testing modern web applications. It automates Chromium-based browsers including Chrome, Microsoft Edge, and Opera, plus Firefox. Tests use JavaScript or languages that compile to JavaScript, such as TypeScript, on Windows, macOS, and Linux systems supported by the latest Node.js LTS. Its API treats the browser as a black box and provides smart selectors without inspecting page source. Taiko waits for pages and elements, including XHR and dynamic content, to finish loading. An interactive recorder REPL can generate readable JavaScript test scripts, while the intercept API supports request and response stubbing. Documentation covers Gauge, Mocha, and Jest integrations; community plugins add accessibility, Android, diagnostics, screenshots, storage, screencasts, and video. Taiko has a self-hosted option but no cloud execution, and it cannot test Safari or mobile applications directly.

Who it suits

Taiko suits developers writing JavaScript or TypeScript browser tests who want open-source, self-hosted automation. It fits Chromium and Firefox web testing rather than Safari or direct mobile-app testing.

Limits

Taiko is available as a free plan. Safari, direct mobile application testing and cloud execution are outside its stated capabilities.

Getting started

1. Open the Taiko website
2. Install Node.js on Windows, macOS or Linux
3. Install Taiko as a Node.js library
4. Write tests in JavaScript or TypeScript
5. Use the recorder REPL or an integration with Gauge, Mocha or Jest

Verdict

Taiko offers readable JavaScript-oriented browser automation with waits, stubbing, and recorder support. Its browser and mobile limits make it better suited to self-hosted web testing than cross-platform device coverage.
