The true and false keywords have two uses:
As literal Boolean values
var myTrueBool = true;
var myFalseBool = false;
As operators that can be overloaded

One can verify whether a method was called on a mock by using Mockito.verify().
Original mock = Mockito.mock(Original.class);

int param2 = 100; // Expected param value
//Do something with mock
//Verify if mock was used properly
Mockito.veri...
