     RoleProvider target = new RoleProvider(userMock.Object, roleMock.Object, userInRoleMock.Object); 

     string[] result = target.FindUsersInRole("test", "cde"); 

     Assert.AreEqual(result[0], "abcdef"); 
     Assert.AreEqual(result[1], "bcdef"); 
     Assert.AreEqual(result[2], "cdef"); 
    }

單元測試代碼

串[]結果= target.FindUsersInRole（「測試」，「CDE」）; < - 錯誤

FindUsersInRole - 獲取用戶名中的用戶名數組，其中用戶名包含要匹配的指定用戶名。

System.NullReferenceException被引發並嘗試調試。

爲什麼NullReferenceException？

PS - FindUsersInRole（RoleProvider）

public override string[] FindUsersInRole(string roleName, string userAccountToMatch) 
    { 
     Guid roleId = roleRepository.GetRole(roleName).RoleId; // RoleId Retrun.. NullReferenceException 

     var roleInUsers = (from ru in usersInRoleRepository.UsersInRoles 
          where ru.RoleId == roleId 
          select ru.UserId).ToArray(); 

     var findUserResult = (from u in userRepository.Users 
           where roleInUsers.Contains(u.UserId) && u.UserAccount.Contains(userAccountToMatch) 
           select u.UserAccount).ToArray(); 

     return findUserResult; 
    }

您將不得不展示如何實現您試圖測試的FindUsersInRole方法。 –

您的cde不是mackUserAccount中的假用戶。請參閱我的下面的答案 –

你CDE是不是假的用戶在mackUserAccount。所以它的返回null。

嘗試以下代碼string [] result = target.FindUsersInRole（「test」，「abcdef」）;而不是

string[] result = target.FindUsersInRole("test", "cde");
