Real-time java API specifications for high coverage test generation
Paper in proceeding, 2012

We present the test case generation method and tool KeYTestGen in the context of real-time Java applications and libraries. The generated tests feature strong coverage criteria, like the Modified Condition/Decision Criterion, by construction. This is achieved by basing the test generation on formal verification techniques, namely the KeY system for Java source code verification. Moreover, we present formal specifications for the classes and methods in the real-time Java API. These specifications are used for symbolic execution when generating tests for real-time Java applications, and for oracle construction when generating tests for real-time Java library implementations. The latter application exhibited a mismatch between a commercial library implementation and the official RTSJ documentation. Even if there is a rationale behind this particular inconsistency, it demonstrates the effectiveness of our method on production code.
