关于pytest框架执行顺序是：

import pytest


class Test_base():

    def setup_class(self):
        print("------->setup_class")
    def teardown_class(self):
        print("------->teardown_class")
    def setup(self):
      print("------->setup_method")
    def teardown(self):
      print("------->teardown_method")

    def test_1(self):
        print('Test_1')
    def test_2(self):
        print('Test_2')
    def test_3(self):
        print('Test_3')
        assert 2 == 1 + 2

    #跳过测试函数：条件、备注
    @pytest.mark.skipif(condition=2 > 1, reason="跳过该函数")
    def test_4(self):
        print('Test_4')

    #标记失败函数：条件、备注
    @pytest.mark.xfail(condition=2 > 1, reason="标记失败该函数")
    def test_5(self):
        print('Test_5')

    #函数参数化：argnames参数名、  argvalues参数对应值，类型必须为list
    #@pytest.mark.parametrize("a",[3,6])
    #@pytest.mark.parametrize("a,b",[(1,2),(0,3)])
    argvalues=[]
    @pytest.mark.parametrize("argnames", argvalues)
    def test_6(self,argnames):
        print('Test_6')

    #自定义标签
    @pytest.mark.shuzf
    def test_shuzf(self):
        #pdb.set_trace()  # 设置断点
        print('shzuf')



if __name__ == '__main__':
    pytest.main(['-s', 'test_demo1.py'])
