Grails单元测试控制器

Question

我试图在这个控制器上进行单元测试。我是这种测试的新手，所以我不知道从哪里开始以及如何测试需要测试的东西，比如用户，渲染视图。）

class ShoppingCartController {

    def shoppingCartWebshopService
    def shoppingCartService
    def springSecurityService
    def checkoutOperaService
    def databaseService
    def dodAdresaService

    def payingOrder(SetShop1Command cmd) {

        def user = springSecurityService.isLoggedIn() ? springSecurityService.currentUser.sifpartnera : null
        def tempAdrese = databaseService.getAdrese(user)
        def adrese = []
        tempAdrese.each{
            adrese.add(it.adresa)
        }

        if (cmd.hasErrors()) {
            render(view: 'OrderChoseAddress', model: [cmd : cmd, params : params, adrese: adrese ])
        }

        def inputUnAdrese = params.inputUnAdrese

        [inputUnAdrese: inputUnAdrese, adrese: adrese]
    }

这是我的测试

@Mock([SpringSecurityService,DatabaseService])
@TestFor(ShoppingCartController)
class ShoppingCartControllerTests {

void testPayingOrder(){

    when:
    // params.user = 19
    // user.equals(id)
    // println user
    // controller.OrderChoseAddress()
        controller.params.user = "admin"
        controller.databaseService = new DatabaseService()

    then:
        assert model.adrese != null
}
