Test Activities for Object-Oriented Software Development

Contradictory statements on testing object-oriented software exist in the literature. On one hand, e.g., Wirfs-Brock, Wilkerson, and Wiener state in [17] that testing object-oriented software is easier than testing non object-oriented software because of classification and encapsulation. On the other hand, e.g., Perry and Kaiser point to specific difficulties in testing object-oriented software, in particular due to inheritance [15].
