Through unit tests, developers verify the correctness of production source code, thereby verifying the system's intended behavior under test. However, unit test code is subject to issues, ranging from bugs in the code to poor test case design (i.e., test smells). In this study, we compare and contrast the occurrences of a type of single-statement-bug-fix known as \"simple stupid bugs\" (SStuBs) in test and non-test (i.e., production) files in popular open-source Java Maven projects.
