Tests involving a large number of test cases and test scenarios are always time- and effort- intensive, and use ad hoc approaches. Test management is needed to control the complexity and the qual- ity of the testing of large software systems. The reporting mechanism is critical for monitoring the testing progress, analyzing test results, and evaluating the test effectiveness for a disciplined testing process throughout the testing lifecycle. This paper presents an XML-based report generation method for large sys- tem testing. The service-oriented architecture enables flexible test report generation, presentation, and ex- change to facilitate collaboration in a distributed environment. The results show that proper reporting can ef- fectively improve the visibility of the testing process and that this web-based approach is critical to enhance communication among multiple testing groups.
