SOArTester: An automatic composite service testing system based on test case reduction

Testing is necessary for the functional correctness, performance, and reliability. The BPMN-based composite services have large number of input parameters and the assigned values of individual parameters, the number of corresponding combinations of input parameters is huge. This paper described a new approach based on combinatorial designs to generate reduced test cases that detect the mutual effect of parameters and based on the method, designed and implemented the SOArTester system, which helps the processes of test cases deployment, execution and monitoring, and the number of test cases generated grows logarithmically in the number of parameters. Experiments demonstrated that SOArTester enhanced the automation level of composite service testing, reduced the testing cost, and improved the efficiency of testing.
