Grails 2.1单元测试命令对象mockForConstraintsTests不工作？ [英] Grails 2.1 Unit Testing Command Object mockForConstraintsTests not working?

问题描述

我已对此命令对象使用手动写入以及Grails生成的单元测试：

 包myapp 
 
 @ grails.validation.Validateable 
类SearchCommand {
 String basisBuild 
 String buildToSearch 
 
 static constraints = {
 basisBuild ）
} 
} 
  

在我手写单元测试失败后， Grails：

  create-unit-test myapp.SearchCommand 
  

我填写单元测试，并对每个关于模拟约束的文档做出应该通过的断言：

  package myapp 
 import static org.junit.Assert。* 
 
 import grails.test.mixin。* 
 import grails.test.mixin.support。* 
 import org.junit。* 
 
 @TestMixin（GrailsUnitTestMixin）
类SearchCommandTests {
 
 void setUp ）{
 mockForConstraintsTests（SearchCommand）
} 
 
 void tearDown（）{
 //拖拽逻辑
} 
 $ b b void testSomething（）{
 SearchCommand commandUnderTest = new SearchCommand（）
 
 commandUnderTest.validate（basisBuild：）
 
 assertEqualsblank，commandUnderTest.errors ['basisBuild'] 
} 
} 
  

遇到此失败？

  grails> test-app 
 |运行9个单元测试... 9/9 
 |失败：testSomething（com.siemens.soarian.sf.gap.SearchCommandTests）
 | java.lang.AssertionError：expected：< blank>但是：< null> 
 at org.junit.Assert.fail（Assert.java:93）
  

方案

我相信我发现grails支持在grails 2.0中单元测试命令对象的方式。

//www.jworks.nl/2012/04/12/testing-command-objects-in-grails-2-0/\">http://www.jworks.nl/2012/04/12/testing-command- objects-in-grails-2-0 /

I have used manually written as well as Grails generated Unit tests for this command object:

   package myapp

    @grails.validation.Validateable
    class SearchCommand {
       String basisBuild
       String buildToSearch

       static constraints = {
          basisBuild(blank: false)
       }
    }

After having my hand written unit test fail I used Grails:

create-unit-test  myapp.SearchCommand

I filled in the Unit Test, and made an assertion that should pass per documentation on mocked constraints:

package myapp
import static org.junit.Assert.*

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

@TestMixin(GrailsUnitTestMixin)
class SearchCommandTests {

    void setUp() {
        mockForConstraintsTests(SearchCommand)
    }

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

    void testSomething() {
        SearchCommand commandUnderTest = new SearchCommand()

        commandUnderTest.validate(basisBuild: "")

        assertEquals "blank", commandUnderTest.errors['basisBuild']
    }
}

Why am I getting this failure?

grails> test-app
| Running 9 unit tests... 9 of 9
| Failure:  testSomething(com.siemens.soarian.sf.gap.SearchCommandTests)
|  java.lang.AssertionError: expected:<blank> but was:<null>
        at org.junit.Assert.fail(Assert.java:93)

解决方案

I believe I found the grails supported way to unit test Command objects in grails 2.0. You need to use mockCommandObject provided by the ControllerUnitTestMixin.
