pytest-接口传参参数化

1、一个参数传值

@pytest.mark.parametrize("a", [3,6,9])
def test_a(self,a):
    print("test data:a=%d"%a)
    assert a%3 ==0

2、多个参数传值

@pytest.mark.parametrize("a,b",[(1,2),(2,1)])
def test_b(self,a,b):
    print("test data:a=%d,b=%d"%(a,b))
    assert  a + b ==3

3、函数返回传值

def return_test_data():
    return [(1,2),(2,1)]

@pytest.mark.parametrize("a,b",return_test_data() )
def test_c(self,a,b):
    print("test data:a=%d,b=%d" % (a, b))
    assert a + b == 3
