right for a trivial case:

def div(top, bottom):
    return top / bottom

def test_div():
    ret =3D div(0,1)
    assert(ret =3D=3D 0)

    try:
        ret =3D div(1,0)
    except:
        pass
    else:
        assert(0) # should have thrown an exception

    ret =3D div(4,2)
    assert(ret =3D=3D 2)
#end test_div

In other words try a few boundary conditions and then a few real cases.
