我是模拟单元测试的新手。

我有这个方法：

    virtual public bool Authenticate(
        Identity identity,
        out IdentityReference entityReference,
        out RightAssignment rights)
    {
        entityReference = null;
        rights = null;

        string passwordHash = identity.Passwd;

        string customerId;
        string userId;

        using (IScope scope = DataAccess.GetScope())
        {
            DA.eCheckResult result = DataAccess.Check(
                    scope,
                    identity.Domain,
                    identity.Login,
                    passwordHash,
                    identity.BranchIdentification,
                    identity.CustomerIdentification,
                    out customerId,
                    out userId);

            if (result == eCheckResult.cOK)
            {
                entityReference = new IdentityReference
                {
                    CustomerId = customerId,
                    UserId = userId
                };

                rights = DataAccess.GetRightAssignment(scope, userId);
            }

            return DA.eCheckResult.cOK == result;
        }
    }

DataAccess 是这样声明的接口：

   public interface IAuthenticateDA : IDisposable
   {
       eCheckResult Check(
            IScope scope,
            string domain,
            string login,
            string passwordHash,
            string branchIdentification,
            string customerIdentification,
            out string customerId,
            out string userId);

        RightAssignment GetRightAssignment(IScope scope, string userId);

        /// <summary>
        /// Gets the scope of the underlying data accessor
        /// </summary>
        IScope GetScope();
   }

我目前的模拟尝试如下所示：

MockRepository mocks = new MockRepository();

IAuthenticateDA mockAuthenticateDA = mocks.StrictMock<IAuthenticateDA>();

string customerId;
string userId;

Expect.Call(mockAuthenticateDA.GetScope()).Return(null);
Expect.Call(mockAuthenticateDA.Check(
    null,
    "orgadata",
    "test",
    "test",
    "branch",
    "customer",
    out customerId,
    out userId)).Return(eCheckResult.cOK);
Expect.Call(mockAuthenticateDA.GetRightAssignment(null, "userId"))
    .Return(MockupDA.Rights);

这是我的错误信息：

这段代码甚至不应该编译。

Expect.Call需要一个Action，所以你想这样做：

Expect.Call(mockAuthenticateDA.GetScope)
      .Return(null);
Expect.Call(() => mockAuthenticateDA.Check(
                      null, "orgadata", "test", "test", "branch", "customer",
                      out customerId, out userId))
      .Return(eCheckResult.cOK);
Expect.Call(() => mockAuthenticateDA.GetRightAssignment(null, "userId"))
      .Return(MockupDA.Rights);

Rhino Mocks 要求您记录您的期望，因此您需要将它们包装在 using 块中。

 using (mocks.Ordered())
 {
   Expect.Call(mockAuthenticateDA.GetScope)
         .Return(null);
   Expect.Call(() => mockAuthenticateDA.Check(
          null, "orgadata", "test", "test", "branch", "customer",
          out customerId, out userId))
         .Return(eCheckResult.cOK);
   Expect.Call(() => mockAuthenticateDA.GetRightAssignment(null, "userId"))
         .Return(MockupDA.Rights);
 }

 mocks.ReplayAll();

 using (mocks.Playback())
 {
      var result = testClass.Authenticate(identity, identityReference);
 }

需要注意ReplayAll将期望明确标记为已记录，因为mocks.Ordered()它本身不会开始记录。您也可以使用 block 将 包装mocks.Ordered在外部开始记录中并删除ReplayAll：

 using (mocks.Record())
 {
   using (mocks.Ordered())
   {
     Expect.Call(mockAuthenticateDA.GetScope)
         .Return(null);
     Expect.Call(() => mockAuthenticateDA.Check(
          null, "orgadata", "test", "test", "branch", "customer",
          out customerId, out userId))
         .Return(eCheckResult.cOK);
     Expect.Call(() => mockAuthenticateDA.GetRightAssignment(null, "userId"))
         .Return(MockupDA.Rights);
   }
 }

 using (mocks.Playback())
 {
      var result = testClass.Authenticate(identity, identityReference);
 }
