我正在写一个相对较小且简单的Windows服务,并使用鼹鼠来模拟单元测试。由于代码很小,我决定使用Moles工具,而不是用代码段来分割代码。当我执行对moled装配任何单元测试,我收到一个错误:“痣需要测试是IN的仪器化进程”摩尔VS2010单元测试Windows服务失败

InitilaizationDetectsMissingMonitorDirectory has failed: Test method FtpDirWatcher.Test.FileWatcherTest.InitilaizationDetectsMissingMonitorDirectory threw exception: Microsoft.Moles.Framework.Moles.MoleInvalidOperationException:

Moles requires tests to be IN an instrumented process.

In Visual Studio Test, add the following attribute your unit test method:

[TestMethod]

[HostType("Moles")] // add this attribute

public void Test() { ... }

我不知道这意味着什么是请注意,“IN”意味着这不是通常的“鼹鼠需要测试成为仪器化过程”。我回顾了文档,看看有没有我错过的东西。我显然仍然缺少重要的东西。

目标组件(“FtpDirWatcher”)确实由Moles检测(由MFileWatcher对象的存在证明),并且我在测试方法上具有适当的属性。我甚至尝试将目标属性转换为方法,但无济于事。发生什么了?

这是精简的代码,所以没有批评!

using System; 
using System.IO; 
using System.Linq; 
using FtpDirWatcher.Moles; 
using Microsoft.Moles.Framework; 
using Microsoft.VisualStudio.TestTools.UnitTesting; 
[assembly: MolesAssemblySettings(Bitness = MolesBitness.AnyCPU)] 

namespace .Test // Test project namespace 
{ 
    [TestClass] 
    public class FileWatcherTest 
    { 
     readonly string _invalidDirectory = @"B:\invaliddirectory"; 

     [TestMethod] 
     [DeploymentItem("FileWatcher.exe")] 
     [HostType("Moles")] 
     public void InitilaizationDetectsMissingMonitorDirectory() 
     { 
      Assert.IsFalse(Directory.Exists(_invalidDirectory)); 

      // THE FOLLOWING LINE OF CODE THROWS THE ERROR. 
      // Use moles to detour the MonitorDirectory property's Get 
      // method to a delegate. 
      MFileWatcher.AllInstances.MonitorDirectoryGet = watcher => 
       new DirectoryInfo(_invalidDirectory); 

      // Don't use the accessor -- no private fields are accessed. 
      var target = new FileWatcher(); 
      Assert.IsFalse(target.IsConfigurationOk); 
     } 
    } 
} 

任何帮助表示赞赏!

更新:添加了以下构建输出。在上面的代码中包含位设置,以表明它不应该成为问题。

这是一个完整的脸部掌上解决方案。我意识到我正在使用DevExpress Tools for Visual Studio附加字形(图标)执行测试,放置在IDE代码窗口中,旁边是测试方法和类。 Moles安装程序会更改Visual Studio测试工具,以包含Moles主机适配器的参数和开关。但是,DevExpress没有被修改。

两种解决方案:

  1. 通过使用Visual Studio测试工具直接
  2. 简单的执行痣测试
  3. 修改的DevExpress工具Visual Studio来正确使用痣主机
