"Object-oriented software differs significantly from traditional procedural software in terms of analysis, design, structure, and development techniques, so specific testing support is also required [FIRESMITH]. The object-oriented language features of encapsulation, polymorphism, and inheritance require special testing support, but also provide opportunities for exploitation by a testing strategy. To adapt structured testing for object-oriented programs, consider both module testing and integration testing. Structured testing at the module level is directly applicable to object-oriented programs, although that fact is not immediately obvious. At the integration level, structured testing does require modification to address the dynamic binding of object-oriented methods. The rest of this section discusses the specific implications of object-oriented programming for structured testing. The majority of this information was previously published in [MCCABE3] and [MCCABE4]."
