/**
 * A command line based tool to run tests.
 * 
 * java junit.textui.TestRunner [-wait] TestCaseClass
 * 
* *

TestRunner expects the name of a TestCase class as argument. * If this class defines a static suite method it * will be invoked and the returned test is run. Otherwise all * the methods starting with "test" having no arguments are run.

* *

When the wait command line argument is given TestRunner * waits until the users types RETURN.

* *

TestRunner prints a trace as the tests are executed followed by a * summary at the end.
