接口自动化项目落地之HTTPBin网站

接口自动化项目落地之HTTPBin网站

接口自动化项目落地系列

找个开源网站或开源项目，用tep实现整套pytest接口自动化项目落地，归档到电子书，作为tep完整教程的项目篇一部分。自从tep完整教程发布以后，tep被越来越多小伙伴了解。教程只是纯理论，是骡子是马，拉出来遛遛才知道。做接口自动化项目落地，一方面是为了让自己脑海中的构想实实在在的呈现出来，现实和理想存在多少差距，不断尝试去弥补和修缮；另一方面也是方便读者朋友们学习使用，借助实际项目来练习，才能在赛道中弯道超车。

只花了3小时完成

通过mitmproxy来录制流量自动生成用例，效率得到了极大的提高，从原来的1天缩短到3小时就完成了整个项目落地。相比于手工编写用例，这次写HTTPBin的接口自动化，我使用了​​utils/mitm.py​​​来录制流量，mitmproxy稍微不方便的是需要手动开启代理，不过适应了以后还是能接受。录制流量后就会生成自动化用例，但是还需要二次修改，才会变成最终的用例。主要修改的工作量是在添加断言，根据业务设置合理的断言。其次是替换url为​​env_vars.domain + "/api"​​​拼接方式，直接批量Replace即可。然后就是修改文件名和​​@allure.title​​了，给用例加上标题。工欲善其事，必先利其器。
