/**
 * Restricts the list of testng tests to run when executed in pure unit test mode (environment specific services
 * are not loaded in the spring context, and any operation relying on them would fail).
 *
 * A test is a pure unit test if either its method, class or parent class is annotated
 * with a @UnitTest annotation (which is not marked as disabled).
 *
 * A method annotation has precedence over a class annotation.
 *
 * Please refer to the testng documentation for various ways or using this interceptor:
 * http://testng.org/doc/documentation-main.html#testng-listeners
 *
 * A simple solution in Eclipse consists in using the setting in testNG plugin, and insert this class name in:
 *
 * Window -> Preference -> TestNG -> Pre Defined Listener
