Test Case Prioritization: A Snowballing Literature Review and TCPFramework with Approach Combinators

Researchers conducted a comprehensive literature review of test case prioritization (TCP) techniques and developed a new framework with ensemble methods called approach combinators. The study analyzed 324 TCP-related studies and proposed new evaluation metrics, with their methods achieving up to 2.7% reduction in regression testing time while performing comparably to state-of-the-art algorithms.

• →A snowballing literature review identified 324 studies related to test case prioritization techniques in software development.
• →Researchers implemented TCPFramework, a comprehensive platform for TCP research and evaluation.
• →Two new evaluation metrics (rAPFDc and ATR) were proposed to better assess TCP performance.
• →Approach combinators consistently outperformed base approaches across majority of subject programs in testing.
• →The new methods achieved up to 2.7% reduction in regression testing time compared to existing approaches.
