如何模拟控制器内部的Command对象 [英] How to Mock Command Object that is inside Controller

问题描述

我有一个控制器类，其中有一个命令对象。我有一个方法find（）使用这个命令对象如下：

  class itemController {
 
 // command object 
 class SearchCommand {
 String email 
 static constraints = {
 email blank：false，email：true 
} 
 
 def find = {SearchCommand sc  - > 
 if（！sc.hasErrors（））{
 ----- do something --- 
} 
 
} 
  

现在，我编写一个测试用例来测试控制器中的find方法。但是测试用例失败了

  if（！sc.hasErrors（））
  

因为sc仍为'null'。我不知道如何处理这个内部类命令对象在测试用例。
我写的测试用例是：

  class itemControllerTests extends ControllerUnitTestCase {
 
 void testFind（）{
 def model = controller.find（）
 assertNotNull（model）
} 
} 
  pre> 
 
 
如何处理测试用例中的内部类Command Object。我模拟吗？我试过使用mockCommandObject（？），但不知道我应该如何将内部类命令对象传递给此？
解决方案
可以使用mockCommandObject 
 
 
 
类RioController 
 
 
 
  class RioController {
 class UserCommand {
 String email 
 static constraints = {
 email blank：false，email：true 
} 
} 
 
 def load = {UserCommand cmd  - > 
 if（cmd.validate（））{
 flash.message =Ok
} 
 else {
 flash.message =电子邮件在哪里？ 
} 
} 
} 
  
 
 
 
类RioControllerTests 
 
 
 
  import grails.test.mixin。* 
 import org.junit。* 
 
 @TestFor ）
 class RioControllerTests {
 
 @Test 
 void testLoad（）{
 mockCommandObject RioController.UserCommand 
 controller.load（）
 assert flash .message ==电子邮件在哪里？ 
 
 params.email =[e-mail]
 controller.load（）
 assert flash.message ==Ok
} 
 } 
  
 
I have a controller class, inside of which i have a command object. I have a method find() which uses this command object as follows:
class itemController{

    //command object
    class SearchCommand{
        String email
        static constraints={
            email blank:false,email:true
        }

def find = {SearchCommand sc ->
    if(!sc.hasErrors()){
     ----- do something---
}

}
Now, I am writing a test case to test the find method in the controller. But the test case fails at 
  if(!sc.hasErrors())
as sc is still 'null'. I am not sure how to handle this inner class command object in the test case.
The test case that i have written so far is:
class itemControllerTests extends ControllerUnitTestCase {

    void testFind(){
    def model = controller.find()
    assertNotNull(model)
    }
}
How do I handle the inner class Command Object in the test case. Do I mock it? I have tried using mockCommandObject(?), but not sure how should i pass the inner class command object to this?
解决方案
You can use mockCommandObject

Class RioController

class RioController {
    class UserCommand{
        String email
        static constraints = {
            email blank: false, email: true
        }
    }

    def load={UserCommand cmd -> 
        if(cmd.validate()){
            flash.message = "Ok"
        }
        else{
            flash.message = "Where is the email?"
        }
    }
}


Class RioControllerTests

import grails.test.mixin.*
import org.junit.*

@TestFor(RioController)
class RioControllerTests {

    @Test
    void testLoad(){
        mockCommandObject RioController.UserCommand
        controller.load()
        assert flash.message == "Where is the email?"

        params.email = "[e-mail]"
        controller.load()
        assert flash.message == "Ok"
    }
}
