GroovyTestCase IJ integration?

In IJ X, if I extend GroovyTestCase and just write some methods with assertions, IJ doesn't detect them to be run in the test runner.  And I can't run the Class as a test as it says "No tests found".  I have to use the JUnit @Test annotation to get it to work.  Is this expected behavior?


See http://groovy.codehaus.org/Unit+Testing

here is a code example:

import

groovy.util.GroovyTestCase class MyTest extends GroovyTestCase {     void testSomething() {         assert 1 == 1         assert 2 + 2 == 4 : "We're in trouble, arithmetic is broken"     } }
