Comprehensive cognizance of regression test case prioritization techniques

Abstract

The worthiness of software can be effectively seen as it emerged as an integral asset that has discovered its application in each field ranging from cell phones to the medicinal treatment, covering practically all electronic devices on earth up to space, for example, satellite communication. In this way, the software has made a way of facilitating and changing the lives of humans. With such involvement of software in the life of humans, it must be developed in a sequential and well-defined way; else its quality will be compromised resulting in unreliable software. Software development is accomplished after undergoing different phases of SDLC. The quality of software can only be ensured by the means of testing. Many testing techniques are available to discover various errors/faults and debugging approaches are thus applied to remove them. One of the approaches for testing the software is exhaustive testing. But its limitation is that it can be applied only on very small programs. Due to time and cost constraints running the exhaustive testing on large programs is not a feasible idea. In regression testing, a whole test suite is executed again to make sure that changes made have not negatively affected the software. This paper has summarized the research findings of numerous researchers in the regression testing field.
