如何设置一个指针属性，以便它可以调用EXPECT_CALL的函数？

class IService {
public:
    virtual ~IService() {}
    virtual void DoSomething() = 0;
};

#include "gmock/gmock.h"

class MockService : public IService {
public:
    MOCK_METHOD(void, DoSomething, (), (override));
};

class TestClass {
protected:
    std::unique_ptr<IService> servicePtr;
};

TEST_F(TestClass, TestDoSomething) {
    // 创建mock对象
    servicePtr = std::make_unique<MockService>();

    // 设置期望
    EXPECT_CALL(*servicePtr, DoSomething())
        .Times(1); // 期望DoSomething被调用一次

    // 调用函数
    servicePtr->DoSomething();
}
