Testing, Documentation and Program Amendment

Abstract

By now you should appreciate that the main feature of JSP is the way in which we proceed from data structures to program code, through well-defined manageable stages (refer to section 1.4). You should also have realised that if we make a mistake, then certain errors may become apparent at an early stage. For example, if data structures without clashes cannot be combined easily, then the structures should be carefully checked to see if they are correct. If you cannot find an obvious position on the program structure for a certain operation, then you should first ascertain whether or not that operation is necessary and then, provided that it is, check the program structure. Having taken due care in applying the principles and rules of JSP, you should always be reasonably confident that the program is correct.
