Abstract

System testing is an essential part of software develop- ment. Unfortunately, comprehensive testing of large sys- tems is often resource intensive and time-consuming. In this paper, we explore the possibility of leveraging hier- archical virtual machine (VM) fork to optimize system testing in the cloud. Testing using VM fork has the po- tential to save system configuration effort, obviate the need to run redundant common steps, and reduce disk and memory requirements by sharing resources across test cases. A preliminary experiment that uses VM fork to run a subset of MySQL database test suite shows that the technique reduces VM run time to complete all test cases by 60%.
