Possibly it has been collected from an existing system, a competitor's system, or a prototype of some sort . Now that you have a pretty good idea that the system will behave correctly under ideal conditions, you need to discover how it will behave under real-world conditions. The time it takes to produce this test code is worth the effort. Your email address is your account identifier.

In software engineering, rubber duck debugging is a method of debugging code.

It has a library of goodies that you can use in your tests to help you test more effectively. Because it will happen again. Pragmatic programmers use feedback to drive their development and personal processes. After you have written a test to detect a particular bug, cause the bug deliberately and make sure the test complains. Failure to meet usability criteria is just as big a bug as dividing by zero. They tend to test gently, subconsciously knowing where the code will break and avoiding the weak spots. Unit testing is the foundation of all the other forms of testing that we'll discuss in this section. That is, you calculate these metrics for every module in the system and see how a particular module relates to its brethren. However, you can't automate everything.
