GoogleMock:期望两个方法调用之一 [英] GoogleMock: Expect either of two method calls
问题描述
我有一个类Foo
,它引用了类型为IBar
的多个其他对象.该类具有方法fun
,该方法需要至少在那些IBar
之一上调用方法frob
.我想编写一个模拟了IBar
的测试来验证此要求.我正在使用GoogleMock.我目前有这个:
I have a class Foo
that references multiple other objects of type IBar
. The class has a method fun
that needs to invoke method frob
on at least one of those IBar
s. I want to write a test with mocked IBar
s that verifies this requirement. I'm using GoogleMock. I currently have this:
class IBar { public: virtual void frob() = 0; };
class MockBar : public IBar { public: MOCK_METHOD0(frob, void ()); };
class Foo {
std::shared_ptr<IBar> bar1, bar2;
public:
Foo(std::shared_ptr<IBar> bar1, std::shared_ptr<IBar> bar2)
: bar1(std::move(bar1)), bar2(std::move(bar2))
{}
void fun() {
assert(condition1 || condition2);
if (condition1) bar1->frob();
if (condition2) bar2->frob();
}
}
TEST(FooTest, callsAtLeastOneFrob) {
auto bar1 = std::make_shared<MockBar>();
auto bar2 = std::make_shared<MockBar>();
Foo foo(bar1, bar2);
EXPECT_CALL(*bar1, frob()).Times(AtMost(1));
EXPECT_CALL(*bar2, frob()).Times(AtMost(1));
foo.fun();
}
但是,这并不能验证是否调用了bar1->frob()
或bar2->frob()
,而不能验证是否调用了两次以上.
However, this doesn't verify that either bar1->frob()
or bar2->frob()
is called, only that neither is called more than once.
GoogleMock中是否有一种方法可以测试一组期望值的最小呼叫次数,例如可以在ExpectationSet
上调用的Times()
函数?
Is there a way in GoogleMock to test for a minimum number of calls on a group of expectations, like a Times()
function I can call on an ExpectationSet
?
