An expert-system technique for object-oriented program testing

Data abstraction, information hiding, inheritance, and dynamic binding are four basic elements used in designing object-oriented (00) programs. These four mechanisms enable programmers to write object-oriented programs that are easily extended, reused and maintained. Software implemented by 00 methodologies has increased software quality and productivity.1 However, this cannot be guaranteed without an appropriate software testing approach. Traditional testing approaches cannot be applied directly to the testing of 00 programs due to the 00 characteristics used in these programs. 00 program testing strategies and methods are proposed continually, but fewer 00 testing tools with flexibility are discussed.
