Grails 2.1.1 - Unit testing and Mocking the elements of domain class

I need a little help in writing Unit tests for my project. I have created Unit test classes for my Controllers and Domain.

My Question is- I have a domain class named employee It has- String id String firstname String middleInitial String lastname String status String empType String userid

And I want to mock them in my setUp() method under test class EmployeeControllerTest()

I have added following Mixin

package EmployeeController

import static org.junit.Assert.*

import grails.test.mixin.*
import grails.test.mixin.support.*
import org.junit.*
import java.io.Serializable

import grails.test.mixin.TestFor
import grails.test.mixin.TestMixin
import grails.test.mixin.Mock
import grails.test.mixin.support.GrailsUnitTestMixin
import grails.test.mixin.domain.DomainClassUnitTestMixin
import grails.test.mixin.services.ServiceUnitTestMixin
import grails.test.mixin.web.ControllerUnitTestMixin
import grails.test.mixin.web.FiltersUnitTestMixin
import grails.test.mixin.web.GroovyPageUnitTestMixin
import grails.test.mixin.web.UrlMappingsUnitTestMixin
import grails.test.mixin.webflow.WebFlowUnitTestMixin

@TestMixin(GrailsUnitTestMixin)
@TestFor(EmployeeController)
@Mock([Employee])

class EmployeeControllerTests {

    void setUp() {
        // Setup logic here

       def Employee ce = new Employee()
       ce.put(empNo: "001", firstname: "amy", middleInitial: "ratr", lastname: "suz", status: "A", empType: "vendor", userid: "amar")
    }

    void tearDown() {
        // Tear down logic here
    }

    void testSomething() {
        //fail "Implement me"
    }

Kindly, let me know if I am missing something or need to do some modifications.

Thanks in Advance :) Amy

Your Unit Test case can be reduced to few lines of code:

package EmployeeController
import org.junit.*

import grails.test.mixin.TestFor
import grails.test.mixin.Mock

@TestFor(EmployeeController)
@Mock(Employee)
class EmployeeControllerTests {
    void setUp() {
       def ce =   
                new Employee(empNo: "001", firstname: "amy", 
                             middleInitial: "ratr", lastname: "suz", 
                             status: "A", empType: "vendor", 
                             userid: "amar").save(flush: true)
    }
}

@TestFor mixin takes care of the contoller mocking. You can very well access some keywords here like controller, contoller.params, controller.request, controller.response without instantiating controller.

@Mock is responsible for mocking the domain class Employee.

you shouldn't use @TestMixin together with @TestFor because TestMixin comes from the old unit testing stuff from grails 1.3 - I suggest removing it
