Unit testing performance with Stochastic Performance Logic

Unit testing is an attractive quality management tool in the software development process, however, practical obstacles make it difficult to use unit tests for performance testing. We present Stochastic Performance Logic, a formalism for expressing performance requirements, together with interpretations that facilitate performance evaluation in the unit test context. The formalism and the interpretations are implemented in a performance testing framework and evaluated in multiple experiments, demonstrating the ability to identify performance differences in realistic unit test scenarios.
