HippoMocks - std :: vector模擬方法無法編譯

嘗試HippoMocks（Cygwin，GCC 4.5.3，CppUnit）模擬一個接口時，其中一種方法導致編譯失敗。進一步的分類表明只有std :: vector作爲參數的模擬方法會失敗。HippoMocks - std :: vector模擬方法無法編譯

例如

m_Mocks.ExpectCall(m_EmpSvcMock.get(), IEmployeeServiceProxy::GetEmployees); // compile error! 
m_Mocks.ExpectCall(m_EmpSvcMock.get(), IEmployeeServiceProxy::AddEmployee); // compile OK!

其中

class IEmployeeServiceProxy 
{ 
public: 
    virtual ~IEmployeeServiceProxy() { } 
    virtual void AddEmployee(const Employee&) = 0; 
    virtual void GetEmployees(std::vector<Employee>&) = 0; 
}; 

struct Employee 
{ 
    boost::uuids::uuid Id; 
    std::string Name; 
};

編譯器錯誤：

那麼你現在已經刪除了錯誤信息，但是在短暫的時間裏我看到它們，我認爲問題在於它試圖將Employee對象與運算符==進行比較。你是否爲Employee類定義了operator ==？ operator == for std :: vector 只要運算符==定義爲T即可運行。 – jahhaj 2012-08-02 06:11:32

@jahhaj：我已經將HippoMocks更新爲svn的最新版本，現在我有一個不同的錯誤... – 2012-08-02 06:21:48

不同的錯誤是？你也沒有回答我的問題，你有運營商==爲員工定義？我認爲這對任何一個Employee類的單元測試都很重要。 – jahhaj 2012-08-02 06:24:57

也許它的抱怨，你沒有操作< <爲員工定義，但我不能肯定。我認爲你錯過了錯誤信息的最後一行？無論如何，我會閱讀文檔，看看他們對正在測試的課程有什麼要求。

要求您定義運算符==和運算符< <，也許其他人對於單元測試框架非常標準。如果您考慮一下，單元測試框架將需要比較您正在測試的類型的對象，並可能在出現問題時嘗試輸出這些對象。

如果該類沒有<<運算符<<定義，那麼在那裏可以自動使用其他東西。它會打印「???」代替。沒有默認的比較，因爲沒有可能的解決方案是合理的。 – dascandy 2012-08-02 06:58:23

@dascandy：我有幾個問題需要注意 - 我如何直接與您聯繫，而不是就此問題提問？ – 2012-08-02 07:09:13

您可以隨時使用我的電子郵件地址[email protected]。我剛剛注意到維基已經腐敗 - 哎呀...我會首先解決它，它應該有大部分的答案，但現在它只有一個數據庫錯誤。 – dascandy 2012-08-02 07:51:09
