Pytest-ordering自定义用例执行顺序

我们一般在做自动化测试时，用例设计之间应该是可以相互独立执行的，没有一定的前后依赖关系的，如果我们真的有前后依赖，想指定用例的先后顺序，可以用到pytest-ordering插件解决这个问题

1、安装依赖包
pip install pytest-ordering

2、运用
用例方法上添加装饰器@pytest.mark.run(order=2)，用例执行顺序会以order值大小升序去调用执行

3、先按Pytest默认执行顺序（根据用例的先后顺序）先执行了用例1（test_login_01）再执行了用例2（test_login_02）

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


class Test(object):

    def test_login_01(self):
        """用例1"""
        print('执行用例test_login_01断言1')
        pytest.assume(1 == 1)
        print('执行用例test_login_01断言2')
        pytest.assume(2 == 2)

    def test_login_02(self):
        """用例2"""
        print('执行用例test_login_02断言1')
        pytest.assume(3 == 3)
        print('执行用例test_login_02断言2')
        pytest.assume(True)


if __name__ == '__main__':
    pytest.main(['-s', 'test_C_01.py'])

4、设置了用例先后顺序为est_login_01（@pytest.mark.run(order=2)）、test_login_02（@pytest.mark.run(order=1)），调用后先执行了用例2（test_login_02）再执行了用例1（test_login_01）

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


class Test(object):

    @pytest.mark.run(order=2)
    def test_login_01(self):
        """用例1"""
        print('执行用例test_login_01断言1')
        pytest.assume(1 == 1)
        print('执行用例test_login_01断言2')
        pytest.assume(2 == 2)

    @pytest.mark.run(order=1)
    def test_login_02(self):
        """用例2"""
        print('执行用例test_login_02断言1')

        print('执行用例test_login_02断言2')
