Why Testing
Why testing, some might wonder? Does it bring any value to the application? You may believe that if a problem is found in your code, it will be reported and eventually be fixed. Therefore, you may argue that testing is fairly irrelevant and is time consuming. If you do believe this, then with the help of this chapter we will try to show you that testing is not just the cherry on the cake but actually it is part of the recipe for success.
Testing is a process during which the application is audited from different perspectives in order to:
Find bugs
Find differences between the expected and real result, output, states, etc.
Understand how complete the implementation is
Exercise the application in realistic situations before its release
The goal of testing is not to put the developer at fault but to provide tools to estimate the health of the application at a given time. Testing measures the quality of an application.
Testing is, therefore, not just a part of the application life cycle...
