....incorrect system executions. Using this method, a correct software implementation should pass tests that describe correct executions and fail tests for incorrect executions. However, this method lacks the systematic treatment of the no change cases provided by our method. Blackburn et al. [4] describe a different method for generating test sequences from SCR specifications, which does not use a model checker. In their method, a tool called T VEC derives a set of test vectors from SCR specifications. In this vector oriented approach, each test sequence is simply a prestate poststate ....

....otherwise [Frankl and Weyuker 1993] A specification can also provide selection criteria to choose, among all possible system behaviors, an adequate test suite. Normally a selection criterion introduces some algorithms or techniques to actually generate test sequences from formal specifications [Blackburn et al. 1997, Gargantini and Heitmeyer 1999, Weyuker et al. 1994] In this paper, we focus on ASM based testing, and tackle several issues in this topic. In particular, we attempt to solve the challenging problem concerning the exploitation of ASMs for defining and implementing methods for generating test ....

....Jin s approach [Jin96] has not yet been automated. The previous approaches are focussed on verifying the correctness of SCR specifications. However, the task of validating whether the operating system complies with the requirements still remains. Towards this end, Blackburn, Busser, and Fontaine [BBF] propose an approach for deriving specification based tests for SCR specifications. The authors describe how an SCR specification can be modeled by a specification in the T VEC system which in turn can be tested using the test vector generator of the T VEC system. The test vector generator ....

.... to testing is referred to as a unit under test (UUT) An important class of SBT tool encompasses those that first generate TestSpecs and then refine them into unit test driver programs (Drivers) Examples of SBT tools in this class are ASTOOT [3] DAIST [4] Daistish [7] DAS BOOT [12] and T VEC [1]. Drivers control and observe UUT behavior via programmatic invocations. Drivers feature an embedded oracle to automatically check UUT test outcomes with respect to TestSpec. Many SBT tools in this class are not modular and tightly couple TestSpec generation and TestSpecDriver translation. ....

....program [12] The primary approach used to provide integration with other tools for the SCR method has been one of translation. The researchers at the NRL have developed a translation from the SCR notation to the state machine notation of a model checker [2, 3, 4, 5] as well as to a testing tool [8]. The primary problems with any translationtype approach are the following: Error reports from the destination tool might be dicult to translate to errors within the source SCR speci cation. Notations must be compatible to some degree or other; otherwise, translation itself will be dicult ....

....Aircraft. This evaluation clarifies the prospective costs and benefits of applying Siddhartha within a software development organization. 1. Introduction Specification based program testing seeks to automate test case generation and test case evaluation by exploiting formal specifications [1, 2, 4, 5, 8, 12, 13, 16, 17]. In specification based testing, a formal specification serves as an unambiguous standard against which the behavior of the program unit under test (UUT) can be automatically compared and as a mechanism by which tests can be developed. Adoption of specification based testing tools in industry has ....

....theoretical considerations and under emphasize application domain specific constraints. For example, many specification based testing tools constrain program units under test and their formal specifications of intended behavior to possess fully encapsulated and syntactically equivalent interfaces [1, 2, 4]. This constraint simplifies translation between test case specifications, which are written in the language and vocabulary of the formal specification, and ground (i.e. variable free) test 2 2 Ada is a registered trademark of the United States government. case input and output data, which ....
