Controller Integration Test

Question

CONTROLLER ACTION:

def deleteDept = {

        def departmentInstance = Department.findByName(params.department.name)

        if (!departmentInstance) {
            println "no dept instance"
            throw new org.codehaus.groovy.grails.exceptions.NewInstanceCreationException ("could not create DeptInstance for ${params.department.name}")
        } else if (departmentInstance.paySvcs && !departmentInstance.paySvcs.isEmpty()){
            println "instance with paySvcs"
            // !!!! do not delete the department if it has payment services !!!!
            departmentInstance.errors.reject('department.do.not.delete.message')
//            render(view: "editDept", model: [departmentInstance: departmentInstance])
            redirect(action: "editDept", id: departmentInstance.id)
        } else{
            println "proceed to delete"
            try {
                departmentInstance.delete(flush: true)
                flash.message = "${message(code: 'default.deleted.message', args: [message(code: 'department.label', default: 'Department'), departmentInstance.name])}"
                redirect(action: "appAdmin", id: departmentInstance.id)
            }
            catch (org.springframework.dao.DataIntegrityViolationException e) {
                println "something went wrong"
                flash.message = "${message(code: 'default.not.deleted.message', args: [message(code: 'department.label', default: 'Department'), departmentInstance.name])}"
                redirect(action: "editDept", id: departmentInstance.id)
            }
        }
    }

INTEGRATION TEST:

        def AppAdminController controller = new AppAdminController()        // create the controller
        controller.metaClass.message = { Map p -> return "foo" }            // message dummy returning garbage - work around the controller message exception
        controller.params.department = [name:"dept1", phone:"817-273-3260", g_password:"password", street:"Main St.", g_userID:"user", unitCode:"1234567", email:"[e-mail]", zip:"75097", fax:"817-273-2222"]
        def dept2 = new Department (name: "Dept2", unitCode: "1234568", street: "Main St.", zip: "75097", fax: "817-273-2222", phone: "817-273 3260", email: "[e-mail]", g_userID: "user", g_password: "password")
        def dept1 = new Department (name: "Dept1", unitCode: "1234568", street: "Main St.", zip: "75097", fax: "817-273-2222", phone: "817-273 3260", email: "[e-mail]", g_userID: "user", g_password: "password")
        def math = new PaySvc()
        def another = new PaySvc()
        dept.paySvcs = []
        dept.paySvcs.add(math)
        dept.paySvcs.add(another)
        mockDomain(Department, [dept1, dept2])

        def svcTest = Department.findByName("Dept1")
        assertNotNull svcTest                                           // record Dept1 exists
        assertEquals 2, svcTest.paySvcs.size()                          // 2 paySvcs total

        controller.deleteDept()                                         // calling the action

        svcTest = null
        svcTest = Department.findByName("Dept1")
        assertNotNull svcTest                                           // record Dept1 still exists, it was not deleted
        // can't test render, controller.response.contentAsString is null
        // but testing at the UI is OK
 //       assertEquals "editDept", controller.response.contentAsString    // action should render "editDept"
        assertEquals "editDept", controller.redirectArgs.action

Question:

render(view: "editDept", model: [departmentInstance: departmentInstance]) 

works when testing manually in the user interface. But in the integration test, controller.response is null when using render, but returns redirectArg when using redirection. Any ideas why?

Answer 1

It may be too late, but it can help someone else: with the help of renderyou you need to use an object modelAndViewon your controller, for example, the following example:

assertEquals controller.modelAndView.model.departmentInstance, departmentInstance

assertEquals controller.modelAndView.viewName, "/test/editDept"

Good luck
