Applying Modified Code Entity-Based Regression Test Selection for Manual End-to-End Testing of Commercial Web Applications

Regression testing plays an important role in maintaining the quality of web applications as they are modified. To reduce the cost of this testing, researchers have proposed a variety of regression test selection (RTS) techniques. The challenges in applying RTS include the lack of tool implementations and the lack of many application requirements such as automated testing and sufficient documentation. This paper presents the challenges and solutions of applying a simple and safe RTS approach to manual E2E testing of legacy web applications, and presents a case study where it is applied to two development projects. Case study results show that this approach can reduce testing more precisely than a test reduction approach based on developer experience with sufficiently low deployment and labor costs.
