 /**
  * {@code Tester} is an abstract test-driver that provides the logic
  * to execute test-cases, grouped by test classes.
  * A test class is a main class extending this class, that instantiate
  * itself, and calls the {@link run} method, passing any command line
  * arguments.
  * <p>
  * The {@code run} method, expects arguments to identify test-case classes.
  * A test-case class is a class extending the test class, and annotated
  * with {@code TestCase}.
  * <p>
  * If no test-cases are specified, the test class directory is searched for
  * co-located test-case classes (i.e. any class extending the test class,
  * annotated with  {@code TestCase}).
  * <p>
  * Besides serving to group test-cases, extending the driver allow
  * setting up a test-case template, and possibly overwrite default
  * test-driver behaviour.
