Homework...
The Pareto Principle:
"...software engineers have developed testing methodologies that improve the odds of revealing errors in software with a limited number of test. One of these is based on the observation that errors in software tend to be clumped. That is experience has shown that a small number of modules within a large software system tend to be more problematic than the rest. Thus by indentifying these modules and testing them more thoroughly, more of the system's errors can be discovered than if all the modules were tested uniformly. In the field of software engineering, the Pareto principle states that results can often be increased most rapidly by applying efforts in a concentrated area..."
(''Pareto'' is in reference to the economist and and sociaologist Vilfredo Pareto 1848-1923, who observed that a small part of Italy's population controlled most of Italy's wealth.)
Glass-box testing as opposed to black-box testing are tests in which "...the tester is aware of the interior structure of the software and uses this knowledge when designing the test..."
