我不確定我想要做的事情是否可行，但我很難讓編譯器嘗試模擬包含模板化參考引數的方法。
介面（洗掉了所有不相關的方法）
class iat_protocol
{
public:
virtual void get_available_operators(etl::vector<network_operator, 5>&) = 0;
};
我的模擬
class at_protocol_mock : public iat_protocol
{
public:
MOCK_METHOD((void), get_available_operators, (etl::vector<network_operator, 5>&), (override));
};
這導致

我的 c 技能還不足以知道編譯器試圖告訴我什么。
誰能幫我 ？

好吧，這很奇怪，但很簡單可以using解決您的問題。
#include "gmock/gmock.h"
struct network_operator {};
namespace etl {
template <typename T, unsigned N>
struct vector {};
} // namespace etl
using vector_5 = etl::vector<network_operator, 5>;
class iat_protocol {
public:
virtual void get_available_operators(vector_5&) = 0;
};
class at_protocol_mock : public iat_protocol {
public:
MOCK_METHOD(void, get_available_operators,
(vector_5&),(override));
};

最新的 gmock 庫顯示了更具描述性的內容：
error: static_assert failed due to requirement '::testing::tuple_size<std::tuple<etl::vector<network_operator, 5> &>>::value == 2' "This method does not take 2 arguments. Parenthesize all types with unproctected commas."
MOCK_METHOD(void, get_available_operators,
用不受保護的逗號將所有型別括起來。
沒有的另一種解決方案using
#include "gmock/gmock.h"
struct network_operator {};
namespace etl {
template <typename T, unsigned N>
struct vector {};
} // namespace etl
using vector_5 = etl::vector<network_operator, 5>;
class iat_protocol {
public:
virtual void get_available_operators(etl::vector<network_operator, 5>&) = 0;
};
class at_protocol_mock : public iat_protocol {
public:
MOCK_METHOD(void, get_available_operators,
((etl::vector<network_operator, 5>&)), (override));
// ^ ^
};
