A TestSuite which will run a Groovy unit test case inside any Java IDE either as a unit test case or as an application.
You can specify the GroovyUnitTest to run by running this class as an application
and specifying the script to run on the command line.
java groovy.test.GroovyTestSuite src/test/Foo.groovy
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...
