为什么 Google Mocks 发现这个函数调用不明确？

我在尝试开始使用 Google Mocks 时遇到了问题 - 由于某种原因它无法告诉我在EXPECT_CALL宏，即使类型是一致的。我想知道为什么它不只匹配第一个函数，以及我需要做什么/添加才能使其匹配第一个函数。

模拟类：

class GMockTest : public ITest
{
public:
MOCK_METHOD2(SetParameter,
    int(int nParameter, double value));
MOCK_METHOD2(SetParameter,
    int(int nParameter, int value));
MOCK_METHOD2(SetParameter,
    int(int nParameter, __int64 value));
}

抛出错误的测试代码：

__int64 nFrom = 0,
    nTo = 0;

EXPECT_CALL(mock, SetParameter(2, nFrom))
    .Times(1)
    .WillOnce(Return(0));
EXPECT_CALL(mock, SetParameter(3, nTo))
    .Times(1)
    .WillOnce(Return(0));

编译错误：

test.cpp(1343) : error C2668: GMockTest::gmock_SetParameter' : ambiguous call to overloaded function
        testmocks.h(592): could be 'testing::internal::MockSpec<F> 
 &GMockTest::gmock_SetParameter(const testing::Matcher<T> &,const testing::Matcher<A2> &)
'
        with
        [
            F=int (int,__int64),
            T=int,
            A2=__int64
        ]
        testmocks.h(590): or       'testing::internal::MockSpec<F>  
&GMockTest::gmock_SetParameter(const testing::Matcher<T> &,const testing::Matcher<T> &)'

        with
        [
            F=int (int,int),
            T=int
        ]
        testmocks.h(580): or       'testing::internal::MockSpec<F> 
&GMockTest::gmock_SetParameter(const testing::Matcher<T> &,const testing::Matcher<FloatT
ype> &)'
        with
        [
            F=int (int,double),
            T=int,
            FloatType=double
        ]
        while trying to match the argument list '(int, __int64)'

Google 模拟无法判断要使用哪个重载。来自cookbook https://github.com/google/googletest/blob/master/docs/gmock_cook_book.md#selecting-between-overloaded-functions-selectoverload，尝试使用Matcher<T> or TypedEq<T>匹配器指定确切的类型：

struct ITest
{
    virtual int SetParameter(int n, double v) = 0;
    virtual int SetParameter(int n, int v) = 0;
    virtual int SetParameter(int n, __int64 v) = 0;
};

struct MockTest : public ITest
{
    MOCK_METHOD2(SetParameter, int(int n, double v));
    MOCK_METHOD2(SetParameter, int(int n, int v));
    MOCK_METHOD2(SetParameter, int(int n, __int64 v));
};

TEST(Test, Test)
{
    MockTest mock;
    __int64 nFrom = 0, nTo = 0;
    EXPECT_CALL(mock, SetParameter(2, Matcher<__int64>(nFrom)));
    EXPECT_CALL(mock, SetParameter(3, Matcher<__int64>(nTo)));

    mock.SetParameter(2, nFrom);
    mock.SetParameter(3, nTo);
}
