httprunner基础
是什么？
面向http（s）协议的通用测试框架。
只需维护一份yaml脚本，即可实现自动化测试、性能测试、线上监控、持续集成等多种测试需求。
约定大于配置。
一站式解决方案，不限于http协议。
为什么？
httprunner3.0新特性
- 概念更简单、功能更易用、生态更强大
- pydantic类型系统
替换jsonschema，做类型的校验
思想来源于golang的struct
- 生成pytest用例
方便定位问题，便于单步调试
jinjia2模版生成
black格式化为标准pep8
- 集成pytest
allure
fixture
- 内置http web server
fastapi
更加易于进行二次开发、平台化
- 测试用例编写语法提示（todo）
httprunner核心概念
测试用例：参考维基百科
测试用例组织结构：用例分层，比如登陆是很常用的用例，把登陆用例分离，其他用例引用。
用例之间应该是没有依赖的。
- 去掉api、testsuite
- 测试用例的格式

环境准备：
建议使用虚拟环境。
1.搭建虚拟环境：
windows系统，新建一个目录，打开cmd，进入到新建的目录中，执行：python -m venv .
或者之间在cmd执行：python -m venv test_httprunner，会在所在目录新建一个目录
执行后，可以看到文件夹：
2.激活虚拟环境：
进入Scripts目录，执行：activate
3.安装httprunner，执行：pip3 install httprunner
注意：返回上一层目录再执行：pip3 install httprunner，最好不要在Scripts目录执行。
如果已经安装过httprunner，升级即可，执行：pip3 install -U HttpRunner。
执行报错：

WARNING: You are using pip version 19.2.3, however version 20.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' comm
and.
执行：python -m pip install --upgrade pip
升级pip。参考：https://jingyan.baidu.com/article/154b4631342f1528ca8f41ee.html
Pip是一个Python的包管理工具，实际上它也可以被看待为是一个包，Pip相当于Linux上的yum，对python的开发者来说相当方便。
我们再也无需去焦头烂额的寻找whl包，直接通过pip就可以在线安装（前提是有网络+pip版本合适的情况下）。
如果pip的版本太老，很多包都无法安装。
看到Successfully字样即升级成功。
安装成功，查看httprunner的版本：hrun -V
4.脚手架生成项目：httprunner startproject test_hru
这个旧命令不能使用了：hrun --startproject test_httprunner
生成测试脚手架异常：
(httprunner_ven) E:\httprunner_ven>hrun --startproject test_httprunner

5.使用pycharm打开项目
注意：是打开test_hrun,而不是hrun-ven
打开后的目录如下：
