• 【pytest】 参数化@pytest.mark.parametrize

    1.创建   test_parametrize.py

    通过

    @pytest.mark.parametrize 方法设置参数
    1. import pytest
    2.  
    3. import math
    4.  
    5. #pytest参数化
    6. @pytest.mark.parametrize(
    7.    "base,exponent,expected",  # 参数变量名称
    8.     # 每个元组都是一条测试用例测试数据
    9.     [
    10.         (2,2,4),
    11.         (3,3,9),
    12.         (1,9,1),
    13.         (0,9,0)
    14.     ],
    15.     ids=['case1','case2','case3','case4']  # 默认为None 用来定义测试用例的名称
    16. )
    17. def test_pow(base,exponent,expected):
    18.     print(base,exponent,expected)
    19.     assert math.pow(base,exponent)==expected

    2.运行结果：pytest -s test_parametrize.py

    pytest -s test_parametrize.py     其中 -s 用于关闭捕捉 

    pytest -v test_parametrize.py   增加测试用例冗长

    pytest --help  查看帮助

    pytest  -q  test_parametrize.py 减少测试冗长

    pytest -x   test_parametrize.py 如果出现一条测试用例失败，就停止

    pytest  ./test_dir    运行测试目录 

    pytest      指定特定类或是方法
