Is it possible to run a single test of a test class in Grails?

We have a very large suite of tests for an app we are developing. I already know how to run specific test classes in either Unit or Integration, e.g.:

grails -test-app -integration FooIntegrationTest

When developing new integration tests, it can take a long time to run through an entire class (say if FooIntegrationTest has 100 tests). I want to run only a specific single test out of the entire test battery.

Is there a way to do this?

Thanks. :)
