Regression Testing of Service-Oriented Software

Regression testing is considered as a separate forms of testing attached with performance testing where tester runs old test suits after each change made to system. It will be a big problem in testing the service-oriented software (SOS), where each system component is inherently agile and changes its behavior dynamically. These agile component gives a big rise to big problem in the regression testing process with respect to complexity, time complexity and cost complexity. A service-oriented software may change in case of bug fixing, adaptation of new environment, upgrading or updating functionality in order to improve performance or it is demanded by customer. After the software is delivered to customer the service oriented software must be regressed to validate that there is no defects. We present a hierarchical regression test selection algorithm for service-oriented software, and evaluate it in service-oriented environment along with results.
