PatternTesting Runtime (patterntesting-rt) is the runtime component for the PatternTesting framework. It provides the annotations and base classes for the PatternTesting testing framework (e.g. patterntesting-check, patterntesting-concurrent or patterntesting-exception) but can be also used standalone for classpath monitoring or profiling. It uses AOP and AspectJ to perform this feat.

There is a newer version: 2.4.0
