我在Visual Studio Ultimate 2010中使用Microsoft Moles并试图诅咒Directory.Exists方法。我在我的程序集和下面的标题行中有mscorlib.moles文件,但在尝试运行单元测试时仍然遇到MoleNotInstrumentedException。我之前使用过微软假货,但我正在使用的项目让我们使用VS2010,所以我必须使用Moles。我已将local.testsettings文件中的主机类型更改为Moles。任何人都有一个想法,为什么单元测试可能会抛出错误或有问题?Microsoft Moles目录存在抛出MoleNotInstrumentedException
using System.IO;
using System.IO.Moles;
using Microsoft.Moles.Framework;
using Microsoft.VisualStudio.TestTools.UnitTesting;
[assembly: MoledAssembly("System.IO")]
[assembly: MoledType(typeof(System.IO.Directory))]
正在测试的简化方法失败。
private bool GetDirectoryExists(string directoryPath)
{
return Directory.Exists(directoryPath);
}
测试方法。
[TestMethod, TestCategory("Developer"), HostType("Moles")]
public void Test_MolesDirectoryExists()
{
string shouldBeValue = @"C:\Hello\Nope\Not Here";
string returnedValue = null;
using (MolesContext.Create())
{
MDirectory.ExistsString = s =>
{
Trace.WriteLine("Passed in value: " + s);
returnedValue = s;
return true;
};
bool result = this.GetDirectoryExists(shouldBeValue);
Trace.WriteLine("DirectoryExists: " + result);
Assert.IsTrue(result, "Directory does not exist.");
Assert.AreEqual(shouldBeValue, returnedValue, "Path values do not match");
}
}
异常错误信息

System.IO.Directory.Exists(System.String path) was not instrumented
