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。

HTTPBin网站

httpbin.org是一个简单的在线提供HTTP服务的网站：

它能够用来对HTTP进行在线测试。

测试报告

HTTPBin网站的接口自动化项目包含11个用例集：

67条测试用例：

自动化执行正确率98.5%，其中有1条错误结果，是我故意为之的，因为想展示下断言失败的效果。

环境配置

包含http和https两套环境，因为HTTPBin支持HTTP&HTTPS：

fixtures/fixture_env_vars.py

代码语言：javascript复制

#!/usr/bin/python
# encoding=utf-8

from tep.fixture import *


@pytest.fixture(scope="session")
def env_vars(config):
    class Clazz(TepVars):
        env = config["env"]

        """变量定义开始"""
        # 环境变量
        mapping = {
            "http": {  # http环境
                "domain": "http://httpbin.org",
            },
            "https": {  # https环境
                "domain": "https://httpbin.org",
            }
            # 继续添加
        }
        # 定义类属性，敲代码时会自动补全
        domain = mapping[env]["domain"]
        """变量定义结束"""

    return Clazz()

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。

tep共建

欢迎添加微信：cekaigang，分享交流tep实践案例，可以提供开源项目我来写，也可以写好后发我一起看看，优秀的项目会添加到tep完整教程的项目篇，以便更多测试同行们借鉴，大佬们赶快来加入我们吧。
