[英]C++ / GoogleTest - How to test member variable of a class being tested
I'm creating tests for a legacy code and wondering if it is possible to check the values of member variables of a class like this (I know my code below is very lousy, bad example :/. Hope to just please focus on the question): 我正在为遗留代码创建测试,并想知道是否可以检查像这样的类的成员变量的值(我知道我的下面的代码非常糟糕,示例很糟糕:/。希望仅关注此问题) ):
class Animal
{
public:
RESULT getInfo();
int age_;
};
int main()
{
Animal animal;
RESULT result = animal.getInfo();
return 0;
}
RESULT Animal::getInfo()
{
age_ = rand() % 10 + 1;
if (age == 5)
{
return success;
}
else
{
return fail;
}
}
And in my test (using Google Test), I call getInfo(): 在测试中(使用Google测试),我调用getInfo():
EXPECT_EQ(success, sut_->getInfo());
However, this just verifies that the result of getInfo()
is success
. 但是,这只是验证了getInfo()
的结果是否为success
。 Is there any other way for me to check the value of age_
without adding a new method/changing the return value? 我还有其他方法可以检查age_
的值而无需添加新方法/更改返回值吗? Thanks! 谢谢!
As you have already made age_
public, you can just add another EXPECT_EQ
statement. 由于已经公开age_
,因此您只需添加另一个EXPECT_EQ
语句即可。 If making age_
public was not intentional then you will have to come with a method to access age_
in GTest
code. 如果不打算公开age_
那么您将必须提供一种在GTest
代码中访问age_
的方法。
