A Generalized Model-Based Test Generation Method

In this paper we present a generalization to the W-method, which can be used for automatically generating test cases.In contrast to the W-method, this generalization allows for test case generation even in the absence of characterization sets for the specification.We give proofs of correctness for this generalization, and show how to derive the original W-method from it as a particular case.Proofs of correctness for the W-method, not given in the original paper, are also presented in a clear and detailed way.
