What it is

Automate web browser interactions to test websites without manually clicking through them.

Real use case example

"A founder wants to test the login feature of a new website. They write Selenium scripts to automate the browser interactions, logging in as a user and verifying the account creation process. They can run these tests in minutes, saving days of manual testing time."
