What is Headless Testing?

Headless testing runs browser-based tests without a visible graphical user interface. Headless browsers execute JavaScript and render pages in memory, making tests faster and suitable for CI/CD environments where a display server is not available. Tools for headless testing include Cypress, Playwright, Puppeteer, Zombie.js, Headless Chrome, Headless Firefox, and HtmlUnit.
