In process of controlling test case need to focus on length: How much complex and precise is the test case? The good test cases length may be 8 to 16 steps (for step-by-step method), unless the tester can't save their work. There are various benefits in keeping test cases short: It requires less time. There is very less chances to make mistakes, or need assistance or some times loss of data. Based on the length of the test case the test manager can accurately estimate how long it will take to test and how much effort we need to spend on it and results are also easily tracked.
