python学习之路_接口参数化1

python接口参数化1

1. 安装pytest框架
2. 熟悉HTTP协议

思路与知识点

• 首先确保自己需要测试的接口能调通
• 确定自己所需要参数化的字段
• 使用pytest框架的装饰器标记数据@pytest.fixture
• 参数化数据必须为列表

直接上手撸代码

# 导包
import requests
import pytest
#定义一个参数化需要的数据，必须是列表！
#undata1 = [['张飞9','111111'],['张飞10','222222'],['张飞11','333333'],['张飞12','444444']]
undata1 = [{'username':'嘘嘘01','password':'111111'},{'username':'嘘嘘02','password':'111111'},{'username':'嘘嘘03','password':'111111'}]

#类似于java上的注解，标记数据源，将数据源给username
@pytest.fixture(params=undata1)
def username(request):
    return request.param

#类名
class Test_no():
    #方法名，传的参数就是，数据给了装饰器，作为参数给了下面的方法
    def test_learn(self,username):
        url="http://localhost:8080/admin/register"
        body={
  "email": "string",
  "icon": "string",
  "nickName": "string",
  "note": "string",
  "password": "12112",
  "username": "11212"
}
        # 数据源是list，使用下标取值，并赋值给body
        #body["username"] = username[0]
        #body["password"] = username[1]

        ## 数据源是Dictionary，使用key取值，并赋值给body
        body["username"]=username["username"]
        body["password"] = username["password"]
        # 调用post方法，传入url,body两个参数
        r1= requests.post(url=url,json=body)
        # 最后输出响应结果
        print(r1.text)
        # 增加断言
        assert r1.json()["message"] == "操作成功"

响应报文

.{"code":200,"message":"操作成功","data":{"id":17,"username":"嘘嘘01","password":"96e79218965eb72c92a549dd5a330112","icon":"string","email":"string","nickName":"string","note":"string","createTime":1552921608805,"loginTime":null,"status":1}}

conftest文件配置

1. conftest.py配置脚本名称是固定的，不能改名称
2. conftest.py与运行的用例要在同一个pakage下，并且有init.py文件
3. 不需要import导入 conftest.py，pytest用例会自动查找

实例

1. 在包中新建一个conftest文件，将数据源放入该文件中，原来文件中数据源删除.png
