Quantification of Regression Test Suite Execution Time in Parallel Execution Setup with Weighted Test Suite Split Algorithm

Regression test suite execution time study focus is essentially on two aspects. They are execution time reduction and making effective use of available hardware resources and manpower. This paper investigates how the regression test suite can be split into subsets to make use of parallel execution across several machines with identical execution speeds and asymmetrical execution speeds. In the symmetrical execution speed setup, long test execution time test cases are evenly distributed across all the hardware machines. However, in asymmetrical execution speed machines, more test cases are distributed to speed machines to make efficient use of hardware resources. In all the situations where there is automation tool to execute the individual test cases of test suite this approach can be employed to make effective use of hardware resources and to keep the execution time within bounds. The Algorithms can also be used in situations where there are queues involved and serial, fixed time service takes place for each of the entity being served.
