Keyboard Test Cases

If you want to test your keyboard specifically the computer keyboard then it requires more than simply seeing the keys work. If you want to validate is the keyboard is working or not simply opening a word processor and typing a few lines will not tell you anything.

Sometimes the keys are working fine but still, there is a chance of an issue with the keyboard device driver. In that case, to successfully test your computer’s keyboard, you need to do so in the Microsoft Windows Device Manager hardware management utility and also need the help of a keyboard tester.
