These are some of the test cases that I can think of while testing the keyboard as per our given specifications. You can come up with more positive and negative test cases for the above tests. I hope this helps you during an interview or while improving your own ability to write effective test cases. Feel free to let me know your opinion and suggestions on my sample test case series.
