Evolutionary testing has been researched and promising results have been presented. However, evolutionary testing has remained predominately a research-based activity not practiced within industry. Although attempts have been made, such as Daimler's Evolutionary Structural Test (EST) prototype, until now, no such tool has been suitable for industrial adoption. The European project EvoTest (IST-33472)...
A Class is not only a template of objects with the same data structure, but also it could be deployed as component and web service in J2EE and .Net platforms. Therefor, Class testing is the key to ensure the quality of a distributed application. Genetic algorithm(GA) has been used to generate test data for class testing. But it has some defects, for example, some individuals would be generated and...
Java PathFinder (JPF) is a popular model checker for Java programs. JPF was used to generate object graphs as test inputs for object-oriented programs. Specifically, JPF was used as an implementation engine for the Korat algorithm. Korat takes two inputs---a Java predicate that encodes properties of desired object graphs and a bound on the size of the graph---and generates all graphs (within the given...
A major issue in software testing is the automatic generation of the inputs to be applied to the programme under test. To solve this problem, a number of approaches based on search methods have been developed in the last few years, offering promising results for adequacy criteria like, for instance, branch coverage. We devise branch coverage as the satisfaction of a number of constraints. This allows...
Software specification is an important element of the software development process. However, in most cases the specifications are out-of-date or even missing. One solution for this kind of problem is to use some process that infers the specification automatically. Work by Ernst et al (2000 ; 2002) has shown how specifications can be generated using program execution traces. These approaches are dependent...
