Writing test cases for an application takes a little practice. A well-written test case should allow any tester to understand and execute the tests, make the testing process smoother, and save a lot of time in the long run. Earlier we posted a video on How To Write Test Cases. I am concluding this post “Test Cases of ATM Machine”.
