WebRTS: A Dynamic Regression Test Selection Tool for Java Web Applications

Regression testing is an expensive activity in software development. To speed it up, regression test selection (RTS) is a promising approach by selecting a subset of tests which are affected by code changes. Although there are lots of regression test selection tools, most of them aim to unit tests, require direct code dependency between tests and code under test, and cannot be applied to Web applications to select end-to-end web tests. This paper presents WebRTS, a dynamic RTS tool for regression testing of Web applications. By tracking the process of Http request and object construction in the server, WebRTS can collect accurate test dependencies for each test in isolation, and supports parallel regression testing of distributed Web application. The design of WebRTS is also flexible, and it can be combined with different web testing frameworks. The experimental results show that WebRTS is effective and can be used to select regression tests for Java Web applications. Video: https://youtu.be/OlAsvrX7HXc.
