Keyword-driven testing is a way to test computer programs or websites. It uses special words or "keywords" to tell the computer what to do. First, you create a list of keywords and then use those keywords to tell the computer what to do. The computer will then do what the keywords say it should do. For example, if you want the computer to do something like open an internet browser, you could use the keyword "Open Browser". Then, the computer will use the keyword to open the browser.
