/**
* A TestSuite which will run a Groovy unit test case inside any Java IDE
* either as a unit test case or as an application.
* <p>
* You can specify the GroovyUnitTest to run by running this class as an application
* and specifying the script to run on the command line.
* <code>
* java groovy.util.GroovyTestSuite src/test/Foo.groovy
* </code>
* Or to run the test suite as a unit test suite in an IDE you can use
* the 'test' system property to define the test script to run.
* e.g. pass this into the JVM when the unit test plugin runs...
* <code>
* -Dtest=src/test/Foo.groovy
* </code>
