Isn't it blackbox testing (or in other words "interface testing")?:
public interface Calculator
{
int sum(int a, int b)
}
public class CalculatorImpl
{
...
}
public class CalculatorTest extends TestCase
{
testSum()
{
Calculator calculator = getImpl();
final a = 2;
final b = 5;
assertEquals(7, calculator.sum(2,5));
}
}
So basically with CalculatorTest I am able to test every implementation of
Calculator interface
Testing with Mock object is often (almost always) white box testing as you
use the knowledge that e.g. class A will call class B
