问题
My question is the same as Mockito: Mock private field initialization but for Google Mock framework. In a nutshell:
class Target {
private:
Person person = new Person();
public:
void testMethod() {
person.someMethod();
}
};
How can I mock the person instance while making unit tests for Target class?
回答1:
A non-answer here: simply don't do it this way.
Your problem is the call to new here. Thing is: that makes testing hard, and it also creates a very tight coupling between the Target and the Person class.
The default alternative is: provide a factory to the Target class that creates Person objects for you.
By going for that solution, you
- avoid to need to mock the call to
new - you end up with a better design!
And unless I am misreading the documentation, mocking calls to new isn't possible with C++ mocking anyway.
