单元测试在 grails 中使用 findwhere 显示控制器的操作

Question

我正在尝试对控制器的显示操作进行单元测试。它的定义是：

def show = {
        //scs 11/22/2011 limit access to users in their Organization
        def currentOrgViewCheck = session.currentUserOrganizationId.viewAllPost;
        def currentOrg = session.currentUserOrganizationId;

        def addressesInstance ;
        if(currentOrgViewCheck){
            addressesInstance = Addresses.findWhere(id:Long.parseLong(params.id));
        }else{
            addressesInstance = Addresses.findWhere(id:Long.parseLong(params.id), organization:currentOrg);
        }


        if (!addressesInstance) {
            flash.message = "${message(code: 'default.not.found.message', args: [message(code: 'addresses.label', default: 'Addresses'), params.id])}"
            redirect(action: "list")
        }
        else {
            [addressesInstance: addressesInstance]
        }
    }

我试图通过模拟地址域来测试它，然后创建并保存一个地址实例，最后将它的 id 传递给控制器​​的参数。但是测试没有通过。
此外，我尝试在我的单元测试方法上测试 findWhere 方法，无论我给它什么参数，它一直说missingMethodException，对于给定的数据类型不存在这样的签名。我完全被困住了。这是我的测试代码：

void testShowFound()
   {
       // New Controller to test
       ac = new AddressesController();

       // this instance is required both to test as well as a session variable
       Organizations org = new Organizations(name:'test', phone: '352-999-8888', createdBy: creator, modifiedBy: modifier, viewAllPost: true);
       org.save();

       //Create an address to pass its id to the action as parameter.
       Addresses a1 = new thlc.Addresses(firstLine:'A1', secondLine:'B', thirdLine:'C', luCountry:UnitedStates, zipCode:'12345', luState:Florida, city:'jag');
       a1.save();   

       ac.metaClass.getParams = {->[id:a1.id] }
       //ac.params.id = a1.id; // I tried both ways.



        // This findWhere is giving error, can any one explain why ?
       //def a = Addresses.findWhere(id:a1.id);
       //assertEquals(a, a1);

       //session variables mocked.
       mockSession['currentUserOrganizationId'] = org;

       // This is to bypass the flash message problem, cause it is not possible to
       // mock the message method on flash messages.
       //ac.metaClass.message = { Map map -> return "ByPass Message" }

       //Call the action and test
       def model = ac.save();
       assert(model);

       //Testing redirect, This is the test that is failing
       assertEquals("list", redirectParams.action);
   } 

我已经尝试了大多数事情，但无法解决它。我错过了什么？谢谢。

在 Grails 1.3.7（及更低版本）中，mockDomain 似乎不会创建 findWhere() 动态查找器。从它的声音来看，如果你想使用它，你必须自己模拟该方法。我自己还没有这样做。
