Unit testing grails controllers with Shiro

[Nguyen, Olivier]

Hi all,

I am trying to write the unit test of a controller's method that uses Shiro.

I followed the instructions at: http://shiro.apache.org/testing.html

I am using Spock to write my tests.

Here is my setup:

I have AbstractShiroTest that extends the Spock Specification class.

My AccountsControllerSpec extends AbstractShiroTest.

@TestFor(AccountsController)
class AccountsControllerSpec extends BaseUnitSpec {
        def 'index'() {
                setup:
                Subject subject = mockFor(Subject)
                setSubject(subject)

                //etc ...
        }
}

I get the following error: Cannot cast object 'grails.test.GrailsMock@429a849' 
with class 'grails.test.GrailsMock' to class 'org.apache.shiro.subject.Subject'

I want to mock the subject so I can mock methods like isPermitted or 
isAuthenticated.

Thanks in advance!
