在模拟googletest时，如何为重载方法指定内部：：AnythingMatcher的参数类型？

#include <gtest/gtest.h>
#include <gmock/gmock.h>

class MyClass {
public:
    virtual void foo(int x) = 0;
    virtual void foo(double x) = 0;
};

class MockMyClass : public MyClass {
public:
    MOCK_METHOD(void, foo, (int x), (override));
    MOCK_METHOD(void, foo, (double x), (override));
};

TEST(MyClassTest, TestFooInt) {
    MockMyClass mock;
    EXPECT_CALL(mock, foo(::testing::_)).Times(1); // 这里会报类型歧义错误

    // 解决方法：明确指定参数类型
    EXPECT_CALL(mock, foo(::testing::Matcher<int>(::testing::_))).Times(1);
    mock.foo(42);
}

TEST(MyClassTest, TestFooDouble) {
    MockMyClass mock;
    EXPECT_CALL(mock, foo(::testing::_)).Times(1); // 这里会报类型歧义错误

    // 解决方法：明确指定参数类型
    EXPECT_CALL(mock, foo(::testing::Matcher<double>(::testing::_))).Times(1);
    mock.foo(3.14);
}
