java - Is there a way to match in Mockito by reference and equals at the same time? -

mockito's matchers has eq() uses equals , same() uses == operator.

is there way use both when comparing objects in mockito?

let's have

list list1 = new arraylist(); list list2 = new arraylist();  system.out.println(list1.equals(list2));  //true system.out.println(list1 == list2);       //false  /* , want check references same,     , list contents haven't changed */ 

so great have operator both checking == , .equals()

this come in handy if want check return same list, , list contents same without doing 2 assertions.

also, may classic example of 4 card problem. https://en.wikipedia.org/wiki/wason_selection_task

.equals() can true if objects don't have same reference.

so .equals() being true doesn't mean == return true , not substitute.

the equals implementation should == check. if doesn´t expect bug. doing both not necessary. if let eclipse generate equals first test == check example.

the same applies list, equals of abstractlist:

public boolean equals(object o) {     if (o == this)         return true;     if (!(o instanceof list))         return false;      listiterator<e> e1 = listiterator();     listiterator e2 = ((list) o).listiterator();     while (e1.hasnext() && e2.hasnext()) {         e o1 = e1.next();         object o2 = e2.next();         if (!(o1==null ? o2==null : o1.equals(o2)))             return false;     }     return !(e1.hasnext() || e2.hasnext()); }
