Abstract

KeYTestGen is a white-box test generator for Java methods based on KeY's program analysis and symbolic execution. KeYTestGen generates a JUnit test harness (test driver) which does not only initialize method parameters but also the global state that is defined by the (potentially private) fields of objects and classes. For example, a complex linked data structure may be created as test input. The tests can satisfy different test criteria such as branch coverage, path coverage, and MC/DC coverage. The user may also provide a specification in the Java Modeling Language (JML) from which a test oracle can be generated or which can be used as an abstraction for a loop or method call. KeYTestGen can be used either as a simple stand-alone tool not requiring expert knowledge or it can be used in an advanced way to support and complement formal verification.
