JUnit-Foundation | JUnit Foundation is a lightweight collection | Unit Testing library

JUnit provides a run listener feature, but this operates most readily on a per-class basis. The method for attaching these run listeners also imposes structural and operational constraints on JUnit projects, and the configuration required to register for end-of-suite notifications necessitates hard-coding the composition of the suite. All of these factors make run listeners unattractive or ineffectual for final cleanup operations. JUnit Foundation enables you to declare shutdown listeners in a service loader configuration file. As shown previously under ServiceLoader Configuration Files, META-INF/services/com.nordstrom.automation.junit.JUnitWatcher is the configuration file where shutdown listeners are declared. By default, this file is absent. To add managed listeners, create this file and add the fully-qualified names of their classes, one line per item. When it loads, the JUnit Foundation Java agent uses the service loader to instantiate your shutdown listeners and attaches them to the active JVM.
