我有一個方法接口和一個模擬該接口的類。該方法只有一個參數。只有當參數類型爲std::pair<Something, Something>
時,纔會編譯失敗。我正在使用MSVC 2010,所以可能的問題是編譯器或STL實現的具體情況,除非這個問題與溼件相關,這是我最好的猜測。我必須失去一些明顯的東西。像納米探針一樣。Google中的std :: pair參數Mocked成員函數無法編譯
#include <gmock/gmock.h>
class BorgInterface
{
public:
typedef std::pair<int, long> MyBorg; // <--- MyBorg is problematic!
//typedef long MyBorg; // ..but this MyBorg complies
virtual void Assimilate(MyBorg borg_in_training) = 0;
};
class MockBorg
: public BorgInterface
{
public:
MOCK_METHOD1(Assimilate, void(BorgInterface::MyBorg borg_in_training));
};
/*TEST(MyBorgTestCase, BorgInterfaceTest)
{
using ::testing::_;
MockBorg funny_borg;
EXPECT_CALL(funny_borg, Assimilate(_));
// ...etc. (irrelevant)
}*/
實際的測試用例不必取消註釋錯誤以表明自己。
現在,我通過將std::pair<>
包裝在struct
中來解決此問題,但這不是最優的。
錯誤消息的長度是相當不幸的,但它可以幫助:

謝謝!我正在考慮提交錯誤報告谷歌模擬,但自從我開始使用它只是在最近,我認爲這更可能是我的錯。 – irobot 2012-03-31 20:43:11
