pytest之@pytest.mark.parametrize實例講解

在測試用例的前面加上：
@pytest.mark.parametrize("參數名",列表數據)
參數名：用來接收每一項數據，並作為測試用例的參數。
列表數據：一組測試數據。

#====參數為列表嵌套字典====
import pytest

def secend(c,b):
    add= int(b)+int(c)
    print(add)
    return add

@pytest.mark.parametrize('case',[{'b':'34','c':'56'},{'b':'39','c':'56'}])
def test_1(case):
    pp=case
    tt=secend(**case)
    print("測試賬號：%s" % tt)


if __name__ == "__main__":
    pytest.main(["-s", "1.py"])
