Automated Model-Based Performance Testing for PaaS Cloud Services

Recently, cloud computing has become popular for its unique advantages. Many applications have been migrated to cloud as web services. However, evaluating the performance of cloud services is non-trivial. Performance testing is one of the dominant techniques for evaluating system performance. In this paper, we present a model and template-based approach that automatically generates test scripts and test cases to measure service performance in an enterprise private cloud. We describe how load is generated automatically from our tool. Our empirical study shows the proposed approach can significantly decrease the cost of performance testing and help reveal potential performance issues.
