4 - Software Testing - 3 - Test Techniques

One of the aims of testing is to detect as many failures as possible. Many techniques have been developed to do this .These techniques attempt to “break” a program by being as systematic as possible in identifying inputs that will produce representative program behaviors; for instance, by considering sub-classes of the input domain, scenarios, states, and data flows. The classification of testing techniques presented here is based on how tests are generated: from the software engineer’s intuition and experience, the specifications, the code structure, the real or imagined faults to be discovered, predicted usage, models, or the nature of the application. One category deals with the combined use of two or more techniques. Sometimes these techniques are classified as white-box (also called glass-box), if the tests are based on information about how the software has been designed or coded, or as black-box if the test cases rely only on the input/output behavior of the software. The following list includes those testing techniques that are commonly used, but some practitioners rely on some of the techniques more than others.
