Gelations is a research prototype system for regression test suite prioritization using genetic algorithms. This system is written entirely in version 1.6 of the Java SE programming language, and is accompanied by its own regression test suite written using the JUnit unit testing framework.
Software testing is a crucial part of the software development lifecycle. Regression testing is a form of testing in which all of the old test cases written to cover different parts of a program are combined into a single test suite and executed. This form of testing helps to reveal regressions, or instances in which code that had formerly functioned correctly is broken by later changes to the system. For real-world applications, however, regression test suites can take days or even weeks to execute. One solution to this problem of execution time overhead is to reduce the suite, removing test cases that are redundant or unlikely to detect faults. This approach, however, can compromise the
