【问题描述】：
我们已经创建了 wcf rest 服务，根据客户的新要求，我们需要为所有服务方法创建单元测试用例。
我完成了研发，发现可以使用一些模拟来完成单元测试。
有人可以用 Visual Studio 2010 中的示例解释一下模拟（开源）。以便我们可以参考并创建相同的单元测试项目。
非常感谢。
以下是我创建帐户的代码，我想使用模拟测试此方法。
[OperationContract]
[WebInvoke(UriTemplate = "CreateAccount", Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]

【问题讨论】：
-
你到底想测试什么？如果您只想在 VS 中使用模拟单元测试任何示例，只需 Google。你会找到足够的。就我个人而言，我喜欢将 NUnit 用于测试、NSubstitute 用于模拟和 ReSharper 用于运行测试的组合。 NUnit 和 NUsbstitute 是开源的，ReSharper 不是。
-
我在内置测试项目中使用 VS 2010。我有一个查询：假设我正在为“CreateAccount”功能创建测试方法，在这种情况下，是否会创建新用户或模拟会阻止它执行，如果是，如何实现？请建议
-
模拟（或者在这种情况下：“存根”）的重点是避免在某些数据库中创建真实帐户。因此，如果您想对您的服务进行单元测试，您将 mock 它用于数据访问的任何类，例如一个存储库。如果您可以发布您的服务类的代码，我可以尝试给您举个例子。
-
感谢您提供信息，我在问题描述中添加了代码。请看一看。谢谢
-
我们可能需要跳过这个方法 "_accountRepository.Add(objAccount);"因此不应创建该帐户。使用 MOQ dll，因为我使用的是相同的。
