T++ is a C++ language extension that aids in systematic testing of C++ code. For each type t used in the code, T++ maintains the set of “typical” values of t, denoted by T(t) (typicals of t). The authors propose an object-oriented testing scheme in which each class t has a test method implemented as a static member function that runs a test script on each of the values in T(t). T++ supports this scheme by automatically generating a default T(t) based on the declaration of t and on the typicals of each of the types used in this declaration. This default can be easily tuned by the class implementor and users to reflect the particularities of the class. T++ also provides an easily tuned by the class implementor and users to reflect the particularities of the class. T++ also provides an easy-to-use mechanism for iterating over the typicals of a type. Thus, T++ gives a supporting environment for the design and implementation of test scripts with the familiar techniques of equivalence testing, boundary value analysis, or functional testing approaches. Most language extensions are realized by either a dedicated pre-processor or by a modification to the compiler. Both techniques suffer from serious drawbacks related to the complexity of C++ and the accessibility of the compiler code. In contrast, the implementation of T++ sidesteps these difficulties by relaying on a novel technique that creates a knowledge base of the source code from the debugging information
