参数化

@pytest.mark.parametrize("a,b",[(1,2),(5,8),(8,0)])
def test_answer(a,b):
    assert func(a) == b

另外可以用 元组或者列表

@pytest.mark.parametrize(("a","b"),[(1,2),(5,8),(8,0)])
def test_answer(a,b):
    assert func(a) == b

@pytest.mark.parametrize(["a","b"],[(1,2),(5,8),(8,0)])
def test_answer(a,b):
    assert func(a) == b
