pytest學習筆記（控制用例的執行順序）

1、pytest加載全部的用例都是亂序的，若是想指定用例的順序，能夠使用pytest-ordering插件，指定用例的執行順序只須要在測試用例的方法前面加上裝飾器@pytest.mark.run(order=[num])設置order的對應的num值，它就能夠按照num的大小順序來執行。

應用場景：有時運行測試用例要指定它的順序，好比有些場景要先須要登入，才能執行後面的流程好比購物流程，下單流程，這時就須要指定用例的執行順序。經過pytest-ordering這個插件能夠完成用例順序的指定。

 

2、安裝

pip install pytest-ordering

 

3、實例

#!/usr/bin/env python
# _*_coding: utf-8 _*_
import pytest


class Testpytest(object):

    @pytest.mark.run(order=-1)
    def test_two(self):
        print("test_two, 測試用例")

    @pytest.mark.run(order=3)
    def test_one(self):
        print("test_one, 測試用例")

    @pytest.mark.run(order=1)
    def test_three(self):
        print("test_three, 測試用例")
