Testing grails controller that has a bean from src/groovy

I have a class in src/groovy

class Something {
  def foo
}

this is in resources.groovy

beans = {
    mySomething(Something)
}

In my Controller I use this :

class MyController {
  def mySomething
  def index () {
    mySomething.foo = "bar"
    render mySomething.foo
  }
}

How do I test this?

   @TestFor(MyController)
   class MyControllerSpecification extends Specification {
     def "test bean"
     given:
       controller.mySomething = new Something() //is this the best way?
     when:
       controller.index()
     then 
       response.contentAsString == "bar"
   }

Question

Is this the best way to test this? I've generally seen Mocks created for classes. What is the benefit of the Mocks and should I be using them here?

You can use defineBeans (refer Testing Spring Beans) while setUp or given since Something has been declared as a bean inside resources.groovy

defineBeans{
   mySomething(Something){bean ->
      //To take care of the transitive dependencies inside Something
      bean.autowire = true 
   }
}

You use a mock implementation of your service if this is faster than creating a new instance and populating the dependencies.

Sometimes you can have a complex service, that depends on other services and the effort of setting up all required structure is high, then you can use Grails mockFor() method and just mock the specific methods that you will use.

Grails docs show you how to mock classes that will be used in your unit test.

In your example I don't see advantages, since Something is just a holder for foo.
