Question 2

In a CI/CD pipeline, what is the primary purpose of running Selenium tests in 'headless' mode?

Accepted Answer

To run tests on servers without a display environment

Answer

Headless mode allows browsers to run without a graphical display, making Selenium tests viable on CI servers that lack a GUI.

Accepted Answer

Xvfb (X Virtual Framebuffer)

Answer

Xvfb creates a virtual framebuffer that simulates a display, allowing GUI browsers to run on headless Linux servers.
