一、pytest加载所有的用例都是乱序的,如果想指定用例的顺序,可以使用pytest-ordering插件,指定用例的执行顺序只需要在测试用例的方法前面加上装饰器@pytest.mark.run(order=[num])设置order的对应的num值,它就可以按照num的大小顺序来执行。
应用场景:有时运行测试用例要指定它的顺序,比如有些场景要先需要登入,才能执行后面的流程比如购物流程,下单流程,这时就需要指定用例的执行顺序。通过pytest-ordering这个插件可以完成用例顺序的指定。
二、安装
pip install pytest-ordering
三、实例
#!/usr/bin/env python # _*_coding: utf-8 _*_ import pytest class Testpytest(object): @pytest.mark.run(order=-1) def test_two(self): print("test_two, 测试用例") @pytest.mark.run(order=3) def test_one(self): print("test_one, 测试用例") @pytest.mark.run(order=1) def test_three(self): print("test_three, 测试用例")
