Unit testing using ControllerUnitTestCase in Grails

I have the following controller:

class MyController {
   def simple = {
      render "simple"
   }
}

An respectively the following test case:

class MyControllerTests extends ControllerUnitTestCase {
   void testSimple() {
      controller.simple
      def body = controller.response.contentAsString
      assertEquals "simple", body
   }
}

I would have expected this test to pass successfully. Surprisingly, it fails with the following result:

junit.framework.ComparisonFailure: null expected:<[simple]> but was:<[]>

I have run the application through the browser and works as expected (i.e. prints "simple).

What am i missing here?

Hi I think your test should look like this:

   void testSimple() {
      controller.simple()
      def body = controller.response.contentAsString
      assertEquals "simple", body
   }

You need to call the simple action(closure).

Thanks,
