我正在尝试实现一个模拟方法并验证只调用它。下面是一个简单的例子,我试图模拟A类:ShowPubA2方法。因此我有以下代码:
class A {
public:
virtual void ShowPubA1()
{
std::cout << "A::PUBLIC::SHOW..1" << std::endl;
}
virtual int ShowPubA2(int x)
{
std::cout << "A::PUBLIC::SHOW..2 " << x << std::endl;
return x;
}
};
class MockA : public A {
public:
MOCK_METHOD0(ShowPubA1, void());
MOCK_METHOD1(ShowPubA2, int(int x));
};
现在我宣布继承自A -
的另一个B类class B : public A
{
public:
int ShowPubB2(int x)
{
ShowPubA2(x);
std::cout << "B::PUBLIC::SHOW..2 " << x << std::endl;
return x;
}
};
以下是我的TEST案例详情:
TEST(FirstB, TestCall) {
using ::testing::_;
MockA a;
EXPECT_CALL(a, ShowPubA2(_)).Times(AtLeast(1));
B b;
EXPECT_EQ(2, b.ShowPubB2(2));
}
从输出中我们可以看到实际的实现被调用而不是模拟方法 - 因此测试失败:
[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from Firstb
[ RUN ] Firstb.TestCall
A::PUBLIC::SHOW..2 2
B::PUBLIC::SHOW..2 2

请让我知道如何模拟一种方法并取而代之的是实际的。
答案 0 :(得分:1)
您应该将{
test: /\.(ttf|eot|woff|woff2)$/,
loader: 'file-loader',
options: {
name: 'fonts/[name].[ext]',
publicPath: '/'
},
},
{
test: /\.(jpe?g|png|gif|svg)$/i,
loader: 'file-loader',
options: {
name: 'img/[name].[ext]',
publicPath: '/'
},
},
更改为注入B
,例如:
A
然后
class B
{
public:
explicit B(A& a) : a(&a) {}
int ShowPubB2(int x)
{
a->ShowPubA2(x);
std::cout << "B::PUBLIC::SHOW..2 " << x << std::endl;
return x;
}
private:
A* a;
};
