A New Dimension of Test Quality: Assessing and Generating Higher Quality Unit Test Cases


Grano, Giovanni (2019). A New Dimension of Test Quality: Assessing and Generating Higher Quality Unit Test Cases. In: Proceedings of the 28th ACM SIGSOFT International Symposium on Software Testing and Analysis, Beijing, 17 July 2019 - 20 July 2019, 419-423.

Abstract

Unit tests form the first defensive line against the introduction of bugs in software systems. Therefore, their quality is of a paramount importance to produce robust and reliable software. To assess test quality, many organizations relies on metrics like code and mutation coverage. However, they are not always optimal to fulfill such a purpose. In my research, I want to make mutation testing scalable by devising a lightweight approach to estimate test effectiveness. Moreover, I plan to introduce a new metric measuring test focus—as a proxy for the effort needed by developers to understand and maintain a test— that both complements code coverage to assess test quality and can be used to drive automated test case generation of higher quality tests.
