In theory, the designer develops a test plan during the
design stage. The tester applies testing techniques based
upon the test plan, corrects the errors, and retests the plan
until he or she achieves the final product. Section 2
introduces the testing techniques. Section 3 describes the
Object-Oriented metrics. Section 4 is devoted to the
implementation of ITC and Section 5 defines the inheritance
test complexity estimation. Finally, a conclusion is
presented.
