6.16. Number of tests

The importance of the plan

It is always good to have a plan when you start working even if you are going to change your plans within a short time. If for nothing else if you use some version control you'll be able to see your progress. (What do you mean you don't have version control ?) Checking if the right number of tests were successfully executed is a test in itself. Some things that can go wrong if you don't check it:

  • Test script dies before running all the tests.

  • Test script dies after running all the tests.

  • You run too many tests - in itself it is not a problem but later when for some reason your test script stops after the correct number of test you won't notice the missing tests.

It is always good to have some plan.
