Question

I’d like to know how do you test your methods if the libs you are using don’t use Interfaces
My class is like

private ThirdParyClass thirdPartyClass;

void myMethod() { 
AnotherThirdPartyClass param = "abc";
...
thirdPartyClass.execute(param);
}

I want to test that execute is called with the “abc” param.

I was thinking in creating MyInterface with an implementation that wraps the ThirdPartyClass and then change the class attribute to refer MyInterface. Quite boring stuff but I don’t see any other way to be able to successfully test my class.
If ThirdParyClass was an Interface I could mock it, but in this case how do you procede?

Answer 1

i do not know which mock implementation you use it. But EasyMock has an extension available at the EasyMock home page that generate mock Objects for classes. See your mock implementation whether it does not support mock Objects for classes.
