Can I run a single unit test from the command line for a Grails project?

Question

I've been running my Grails unit tests by typing grails test-app :unit, which runs all unit tests. Is there a way to specify a single test?

Edit: So far, everyone is basically saying the same thing, but when I do that, no tests are run. Any more thoughts?

Conclusion: OK, I was using the name of the test class, rather than the name of the class being tested. Once I tried Foo instead of FooTests it worked perfectly.

Possibilities of things that might be wrong with your setup:

• Your command order is incorrect. What works for me is:

  grails test-app -unit Foo (where my test class is FooTests.groovy)

• You aren't explicitly importing grails.test.GrailsUnitTestCase.

  I had some problems with it recognizing my tests when I didn't import this. When I was extending GroovyTestCase, things seemed to work normally.

Working Example

Here's a sample set of tests that work for me. Perhaps you can spot some differences between them and your tests?

Note: These are all run with the testing plugin installed

test/unit/FooTests.groovy

import grails.test.GrailsUnitTestCase
class FooTest extends GrailsUnitTestCase {
    void testFoo() {
        assert true
    }

    void testBar() {
        assert true
    }
}

test/unit/BarTests.groovy

import grails.test.GrailsUnitTestCase
class BarTest extends GrailsUnitTestCase {
    void testFoo() {
        assert true
    }

    void testBar() {
        assert true
    }
}

test/unit/my/pkg/BazTests.groovy

package my.pkg

import grails.test.GrailsUnitTestCase

class BazTest extends GrailsUnitTestCase {
    void testFoo() {
        assert true
    }

    void testBar() {
        assert true
    }
}

command: all unit tests

$ grails test-app -unit

I tried these in Grails 1.2.3 and Grails 1.3.4, both behaved the same.
