Load testing of web applications can be specified by simulating realistic user behavior with stochastic form-oriented analysis models. Stochastic models have advantages over load test models that simply play back recorded session data: they are easier to specify and achieve a higher coverage of the different operational paths. There are challenges when specifying load tests such as the generation of form parameters and the recognition of pages returned by the system. We propose how these challenges can be overcome by adding additional specifications to a form-oriented model. Furthermore, we discuss several workload models and explain why some commonly used workload models are in fact unrealistic and produce misleading results. The stochastic form-oriented load testing approach can be generalized to deal with other submit-response systems such as those consisting of web services.
