Python Instance.isinstance Examples

Example #1

def test_isinstance():
    # Python code
    class A(object):
        pass
    class B(A):
        pass
    b = B()
    assert isinstance(b, B)
    assert isinstance(b, A)
    assert isinstance(b, object)
    assert not isinstance(b, type)

    # Object model code
    A = Class(name="A", base_class=OBJECT, fields={}, metaclass=TYPE)
    B = Class(name="B", base_class=A, fields={}, metaclass=TYPE)
    b = Instance(B)
    assert b.isinstance(B)
    assert b.isinstance(A)
    assert b.isinstance(OBJECT)
    assert not b.isinstance(TYPE)
