Test Case For Keyboard

Test Case For Keyboard Test Or Test Scenarios For Keyboard: I will explain the test cases for keyboards in this post. Most of the interviewers often ask about the test cases related to computer accessories. 

Keyboard and Mouse test cases are quite often asked. As I have already covered the test cases related to a mouse, this post will focus on the test scenarios for the keyboard. We assume this keyboard to be PS/2 or USB-powered. There is also a wireless or Bluetooth-based keyboard, but we are going to skip those models for the sake of simplicity.

Keyboard Test Cases

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

Sometimes the keys are working fine, but there is still 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 the help of a keyboard tester.

What is a keyboard tester?

A keyboard tester tests the accuracy of keyboards and other input devices. They may do this by using software or a physical keyboard to test for errors, typos, and malfunctions. Depending on the job requirements, a keyboard tester may be required to know various computer languages (such as English), programming constructs (like database queries), Operating Systems principles, or application usage patterns.

I can think of some of the test cases while testing the keyboard per our specifications. You can develop more positive and negative test cases for the above tests. I hope this helps you during an interview or improves your ability to write effective test cases. Please let me know your opinion and suggestions on my sample test case series.
