2020-02-20 pytest框架的一些整理

1.使用pytest.fixture

#定义数据，数据必须是列表
data = [{"username":"xue1","password":'123'},{"username":"xue2","password":'234'},{"username":"xue3","password":'345'},{"username":"xue4","password":'456'}]

def id(mark_vaule):
    return "username,password".format(mark_vaule)


#fixture标记函数 data 表示需要标记的数据列表
@pytest.fixture(params= data,ids=id)
def username(request):
    return request.param

    #username,表示使用哪个fixture标记的函数
    def test_sign(self,cus_column):
      print(cus_column["password"], cus_column["username"])
      # 可以做网络请求
      pass

if __name__ == "__main__":
    # 生成报告目录文件
    pytest.main(['-s', '-v', 'xxx.py::test_sign'])

2.Pytest装饰器@pytest.mark.parametrize
代码1：

import pytest
# 单参数单值
@pytest.mark.parametrize('user', ['admain123'])
def test(user):
    print(user)
