How to mock abstract class with static members in Grails?

Question

I need to mock a GrailsControllerClass interface. Instance should have a static variable defined. The problem is that MockFor and StubFor don’t give you an option for adding static members. So, I write my abstract class that extends GrailsControllerClass

abstract class MyController implements GrailsControllerClass {
   static myDefinition  = [name:"item1", action:"action1"]
}

Now, MockFor and StubFor raise an error: groovy.lang.MissingMethodException: No signature of method: groovy.util.ProxyGenerator.instantiateAggregateFromBaseClass() is applicable for argument types: (java.lang.Class, null) values… which seems to be a reported bug: http://jira.codehaus.org/browse/GROOVY-3720 Alas, grails comes with groovy 1.6.

I do not want to make MyController a huge concrete class with empty method declarations. Any alternatives?

Answer 1

Have you tried GMock, yet? It supports mocking of static methods.

Answer 2

You could tweak the metaClass I believe:

GrailsControllerClass.metaClass.'static'.myDefinition = [name:"item1", action:"action1"]

Or use a map to mock your controller interface:

def myController = [getMyDefinition:{[name:"item1", action:"action1"]}] as GrailsControllerClass

I'm not sure based on your post if that's what you're looking for or not.
