Question

我试图模拟硬件抽象层函数，通过编写假的uint32_t hw_epoch()和伪调用模拟方法，这将让我验证hw_epoch()函数是否已开始调用。所以考虑下面的简化代码：

#include <stdint.h>
#include "gmock/gmock.h"

using ::testing::Return;

class FooInterface {
 public:
    virtual ~FooInterface() {}
    virtual uint32_t m_hw_epoch() = 0;
};

class MockFoo : public FooInterface {
 public:
    MOCK_METHOD0(m_hw_epoch, uint32_t());
 private:
};

// ----- Test Fixture:
class FooTest : public ::testing::Test {
 public:
    FooTest() : FooInterfacePtr(&MockFooObj) {}
    ~FooTest() {}

    MockFoo MockFooObj;
    FooInterface* FooInterfacePtr;
};

// ----- Fakes
uint32_t hw_epoch() {
    FooInterfacePtr->m_hw_epoch();  // *** How Can I access FooInterfacePtr?
    return 5;
}

TEST_F(FooTest, constructor) {
}

FooTest Fixture有成员FooInterfacePtr，如何从免费功能uint32_t hw_epoch()访问此成员？

谢谢你...
