How can test cases be executed on any browser in headless mode?

Question

Accepted Answer

Test cases can be executed in headless mode using browsers like Chrome and Firefox without a graphical user interface.

Headless Browsers: Tools like Chrome and Firefox can run in headless mode, allowing tests to execute without a GUI, improving speed and resource usage.
Selenium WebDriver: Use Selenium with headless options, e.g., 'options.add_argument('--headless')' for Chrome to run tests without opening a window.
Cypress: Cypress supports headless mode natively, allowing you to run tests in the background using 'cypress run' command.
Puppeteer: Puppeteer is a Node library that provides a high-level API to control Chrome in headless mode, ideal for automated testing.
CI/CD Integration: Headless testing is often integrated into CI/CD pipelines, enabling automated testing in environments without a display.
