On Built-in Tests in Object-Oriented Reengineering

: This paper provides a new approach for object-oriented reengineering. One of the difficulty in software testing and maintenance has been identified as caused by the convention that code and its tests are developed and described separately. This paper develops a method of built-in test (BIT) for OO reengineering. The advantage of this method is that the BITs in reengineered OO software (OOS) can be inherited and reused as that of code. Therefore building tests into the conventional software during OO reengineering can be a significant reengineering approach for the existing OO legacy systems. Key words: Software engineering, OO reengineering, OOP, built-in test, test reuse, testable software 1. Introduction Object-oriented programming (OOP) [1,2] is the natural extension of the structured programming [3] and abstract data types (ADTs) [4] with new concept of abstraction, encapsulation, inheritance and reusability. The most powerful feature of OOP is the availability of reuse by inhe..
