Question

I have a controller action that checks a condition and based on the condition’s result, it will set a field to session variable

Controller:

def checkUser={
    if(condition: true){
       session.user = id
    }else{
       session.user=null
    }
}

Now, in my testcase, if I have to assert on this session’s user value, how do i do it?

I tried it like this, but it did not work:

void testSomething(){
    controller.checkUser()
    assertNull(session.user)
}

Any idea on how to assert session variable which is being set in the controller?

Answer 1

Make sure your test class extends ControllerUnitTestCase or is using the test Mixin.

CUTC offers several mocks to facilitate Controller testing. Here’s what you’ll do:

void testSomething(){
    controller.checkUser()
    assertNull(mockSession.user)
}
