Extending Stream X-machines with Probability Intervals to Test Web Software
Zhongsheng Qian · International Journal of Hybrid Information Technology · 2016
The essential purpose of testing is to detect and remove faults in the implementation of a system.This study presents a pragmatic usage model based on Probabilistic Stream X-machines (PSXMs for short).The PSXM, which is an extended SXM with the transitions enhanced with probability intervals, is capable of describing both the data and the control aspects of a given system.The test case generation process is given based on the PSXM usage model.It takes the self-developed SWLS (Simple Web Login System), a miniature web software as a running example to demonstrate the testing method.The testing process ensures that the failures occurring most frequently in operational uses will be found early.This testing approach proposed lends itself to exploring new model-based testing techniques.
