调用模拟方法的预期方法时调用方法 [英] Calling a method when expected method on mock was invoked
问题描述
我有以下情况:
class InterfaceA;
class InterfaceB;
class InterfaceC;
class InterfaceA
{
virtual void foo(InterfaceC&) = 0;
};
class InterfaceB
{
virtual void bar() = 0;
};
class InterfaceC
{
virtual void bla() = 0;
};
// MOCKs
class MockA : public InterfaceA
{
public:
MOCK_METHOD0(foo, void(InterfaceC&));
};
class MockB : public InterfaceB
{
public:
MOCK_METHOD0(bar, void());
};
class ImplC : public InterfaceC
{
public:
ImplC(InterfaceA& a, Interface& b) : m_a(a), m_b(b) {}
void doSomething() {
m_a.foo(*this);
}
virtual void bla()
{
m_b.bar();
}
};
MockA mockA;
MockB mockB;
EXPECT_CALL(mockA, foo());
ImplC impl(mockA, mockB);
impl.doSomething(); // will call foo on mockA
如果调用doSomething,则将在MockA上调用foo.万一将调用foo,我如何触发方法bla的调用?是否可以通过某种方式创建期望:
In case doSomething is invoked, foo will be called on MockA. How can I trigger an invocation of the method bla, in case foo will be invoked? Is it somehow possible to create an expectation like:
EXPECT_CALL(mockA, foo()).WillOnce(Invoke(impl.bla()));
?
我希望答案是明确的,例子也是这样.
I hope the answer is clear and the example too.
先谢谢了. 玛特
推荐答案
EXPECT_CALL(mockA, foo()).WillOnce(InvokeWithoutArgs(&impl, &ImplC::bla));
应该工作.如果必须传递更复杂的参数,请使用boost :: bind(请注意,类实例和方法在参数列表中的顺序不同):
Should work. If you have to pass more complex parameters, use boost::bind (notice the different order of the class instance and method in the parameter list):
EXPECT_CALL(mockA, foo())
.WillOnce(Invoke(boost::bind(&ImplC::bla, &impl, other_params)));
如果给了foo()
一些应传递给bla()
的参数,请使用WithArgs
:
And if foo()
is given some parameters that should be passed into bla()
, use WithArgs
:
EXPECT_CALL(mockA, foo(Lt(1), _))
.WillOnce(WithArgs<0>(Invoke(&impl, &ImplC::bla)));
还可以看看Google Mock 备忘单Wiki页面-它提供有关函数和方法调用操作的更多信息.
Also take a look at the Google Mock Cheat Sheet wiki page - it provides more information about function- and method calling actions.
