| * ``spy_return``: contains the last returned value of the spied function. | ||
| * ``spy_return_iter``: contains a duplicate of the last returned value of the spied function if the value was an iterator and spy was created using ``.spy(..., duplicate_iterators=True)``. Uses `tee <https://docs.python.org/3/library/itertools.html#itertools.tee>`__) to duplicate the iterator. | ||
| * ``spy_return_list``: contains a list of all returned values of the spied function (new in ``3.13``). | ||
| * ``spy_return_list``: contains a list of all returned values of the spied function (new in ``3.13``). If the mock was called multiple times, the list is sorted descendingly: the last value comes first. |

There was a problem hiding this comment.
This is not right, the last call comes last:
class C:
def foo(self, x): return x
def test(mocker):
spy = mocker.spy(C, "foo")
c = C()
c.foo(10)
c.foo(20)
print(spy.spy_return_list)
assert 0----------------------------- Captured stdout call -----------------------------
