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)
