Are you tired of documenting the same things over and over again and spending too much time preparing documentation instead of focusing on testing? Are you interested in just improving the test ideas instead of reinventing them constantly? Cheat sheets are finally legal, and there is now a benefit of their use. Use some of the existing available Cheatsheets, or just develop your own.
Developing test cases and wasting precious time should stay in the past, and more intensive testing should be achieved. Test Cases are dead... Long Live the Cheatsheets!
