47   * A TestSuite which will run a Groovy unit test case inside any Java IDE
48   * either as a unit test case or as an application.
49   * <p/>
50   * You can specify the GroovyUnitTest to run by running this class as an appplication
51   * and specifying the script to run on the command line.
52   * <p/>

57   * Or to run the test suite as a unit test suite in an IDE you can use
58   * the 'test' system property to define the test script to run.
59   * e.g. pass this into the JVM when the unit test plugin runs...
