Gamera: A Tool For Ws-Bpel Composition Testing Using Mutation Analysis

This paper shows a novel tool, GAmera, the first mutant generation tool for testing Web Service compositions written in the WS-BPEL language. After several improvements and the development of a graphical interface, we consider GAmera to be a mature tool that implements an optimization technique to reduce the number of generated mutants without significant loss of testing effectiveness. A genetic algorithm is used for generating and selecting a subset of high-quality mutants. This selection reduces the computational cost of mutation testing. The subset of mutants generated with this tool allows the user to improve the quality of the initial test suite.
