What is headless Chrome Selenium Python?
Headless means that the browser is running without a display. The tests are run in an environment where they can’t see the website’s visual output. Headless Chrome allows to run most of the test functions that you would normally do with PhantomJS (or any other headless browser) but with more power and speed. Since it is based on Chromium, you have access to all the Chrome Dev Tools and all the extensions available for it.
