[接口测试_B] 13 pytest+requests实战练习1

接续这个文集中的文章：https://www.jianshu.com/nb/23293583

找不到免费的接口，所以依然以requests官方文档中出现的httpbin为示例，为了保持网络的稳定，可以把httpbin搭建在本地。

httpbin环境搭建

• VMware12
• ubuntu kylin 16.04_x64
• python3.5

sudo apt-get install python3-pip

• 安装虚拟环境，pipenv：

python3 -m pip install pipenv
# 在项目目录下
pipenv install
# 进入虚拟环境
pipenv shell

在安装pip后，创建虚拟环境，安装httpbin和gunicorn：

pipenv install httpbin
pipenv install gunicorn

启动httpbin,如果启动后，宿主机无法访问，查看防火墙设置，把端口加入iptables：

gunicorn -b :8088 httpbin:app

测试httpbin接口

前面了解requests的过程中，多次用到httpbin接口做示例。对这个接口应该比较熟悉了。先实现简单的接口测试。

运行pytest命令

• 运行pytest命令直接查看结果：

pytest -q run.py

• 运行pytest命令生成测试报告：

pytest -q --tb=no --html=E:\python_interface_test\results\makehtml.html

总结

• 在一个py文件中编写了一堆用例，并且能够输出报告了，终于踏出了第一步
• 缺点说明：
  1、没有进行数据隔离：接口、请求参数、断言数据都在同一文件中；
  2、不能设置配置信息：如测试地址改变等，不能直接通过配置文件修改；
  3、没有记录日志信息：没有记录接口的执行信息，如果出现bug，无法提供定位信息；
