Approaches in Regression Testing Based on Test Case Prioritization: A Systematic Literature Survey

Soft-ware quality can be assured by going through soft-ware testing process. However, soft-ware testing phase is an expensive process as it consumes a longer time. By scheduling test cases execution order through a prioritization approach, soft-ware testing efficiency can be improved especially during regression testing. It is a notable step to be taken in constructing important soft-ware testing environment so that a system's commercial value can increase. The main idea of this review is to examine and classify the current test case prioritization approaches based on the articulated research questions. Test case prioritization has already been considerably discussed in the soft-ware testing do- main. However, it is commonly learned that there are quite a number of existing prioritization techniques that can still be improved especially in data used and execution process for each approach.
