ubuntu16.04.3 python 多版本改造与 HttpRunner 部署
http://httprunner.readthedocs.io/en/latest/quickstart.html
项目中的 tests 目录有一个 api_server.py 接口 API 样例服务
为了得到该 api_server.py 先 git 该项目
cmd@TR:~/workspace/git$ git clone https://github.com/HttpRunner/HttpRunner.git

然后到 pyenv363 环境启动服务 ,需要 Flask-Script 支持
(pyenv363) cmd@TR:~$ pip install Flask-Script

尝试启动，报找不到
(pyenv363) cmd@TR:~$ export FLASK_APP=tests/api_server.py
(pyenv363) cmd@TR:~$ flask run
Usage: flask run [OPTIONS]
Error: The file/path provided (tests/api_server.py) does not appear to exist. Please verify the path is correct. If app is not on PYTHONPATH, ensure the extension is .py
此处注意 一定要先 cd 切换到该目录/workspace/git/HttpRunner/ 也就是 tests 目录的上一级处再执行 export 和 flask run 方可正常开启模拟 API Server
(pyenv363) cmd@TR:~/workspace/git/HttpRunner$ export FLASK_APP=tests/api_server.py
(pyenv363) cmd@TR:~/workspace/git/HttpRunner$ flask run
* Serving Flask app "tests.api_server"
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
127.0.0.1 - - [26/Dec/2017 10:15:01] "GET /api/users/1000 HTTP/1.1" 401 -
127.0.0.1 - - [26/Dec/2017 10:15:28] "GET /api/get-token HTTP/1.1" 405 -
然后才可以正常访问
http://127.0.0.1:5000/api/get-token
http://127.0.0.1:5000/api/users/1000
测试目录存放样例 API Server
https://github.com/HttpRunner/HttpRunner/tree/master/tests
样例 API Server 的 test case 目录
https://github.com/HttpRunner/HttpRunner/tree/master/examples
样例服务的存放脚本在路径：
(pyenv363) cmd@TR:~/workspace/git/HttpRunner/examples$ ls
debugtalk.py quickstart-demo-rev-0.yml quickstart-demo-rev-2.yml
init.py quickstart-demo-rev-1.yml quickstart-demo-rev-3.yml
执行 ate quickstart-demo-rev-1.yml 或 httprunner quickstart-demo-rev-1.yml 执行 test case
(pyenv363) cmd@TR:~/workspace/git/HttpRunner/examples$ httprunner quickstart-demo-rev-1.yml

可自行测试学习
我们也可以自行测试某一网站比如 H5 常规注册 API
访问地址 http://m.aicai.com/m/register.do?agentId=14759&vt=5 添加账号 非法密码 手机号 提交 立即注册
请求网址 http://m.aicai.com/m/saveSimpleRegister.do?agentId=14759&vt=5
下图为 postman 的 常规注册测试。你也可以用它来查看请求 请求头 Headers 请求体 Body 字段。同时 HttpRunner 今后也将支持
Integrate with PostMan: convert Postman Collection Format to YAML testcases.
已经替代 firebug
比如根据以上工具查看接口请求与响应得到的信息 我们可以如下：
- test:
name: regist user which passwd is wrong
request:
url: http://m.aicai.com/m/saveSimpleRegister.do?agentId=14759&vt=5
method: POST
headers:
User-Agent: 'iOS/10.3'
token: content.token
json:
account: "postsay1"
password: "%^&*()"
phone: "13751077575"
isProtocol: on
ajaxReq: 1
validate:
# - {"check": "status_code", "comparator": "eq", "expect": 200}
# - {"check": "content.status", "comparator": "eq", "expect": error}
# - {"check": "content.msg", "comparator": "str_eq", "expect": 请仔细阅读爱彩网服务协议并同意！}
- eq: ["status_code" , 200]
- eq: ["content.status" , error]
- eq: ["content.msg" , 请仔细阅读爱彩网服务协议并同意！]
（注释掉的 valiadate 两种写法都有效）
保存脚本到某一路径下，切换到该路径下执行 httprunner 命令或 ate 命令即可执行 testcase 脚本
(pyenv363) cmd@TR:~/scripts/locust$ httprunner ac-h5.yml
Running tests...

为了支持 locusts 做性能测试 我们还需要单独安装下 locusts
(pyenv363) cmd@TR:~$ pip install git+https://github.com/locustio/locust.git@master#egg=locustio
(pyenv363) cmd@TR:~$ locusts -V
[2017-12-22 17:15:15,642] TR/INFO/stdout: Locust 0.8.1
[2017-12-22 17:15:15,642] TR/INFO/stdout:
https://testerhome.com/topics/9832
既然说了已经包含了 locust 为什么还要单独安装 看这篇即可明白。作者只是写了个 locustfile.py。
第二种，就是生成 locustfile.py 这样一个中间文件，然后将文件路径传给 Locust。这样的好处在于我们可以不改变 Locust 的任何地方，直接对其进行使用。与 Locust 的传统使用方式差异在于，之前我们是在 Terminal 中通过参数启动 Locust，而现在我们是在 ApiTestEngine 框架中通过 Python 代码启动 Locust。
具体地，我在 setup.py 的 entry_points 中新增了一个命令 locusts，并绑定了对应的程序入口。
最后
安装 httprunner 后，系统中就具有了 locusts 命令，使用方式跟 Locust 框架的 locust 几乎完全相同，我们完全可以使用 locusts 命令代替原生的 locust 命令。
例如，下面的命令执行效果与 locust 完全一致。
$ locusts -V
$ locusts -h
$ locusts -f locustfile.py
$ locusts -f locustfile.py --master -P 8088
$ locusts -f locustfile.py --slave &
差异在于，locusts 具有更加丰富的功能。
在 httprunner 中编写的 YAML/JSON 格式的接口测试用例文件，直接运行就可以启动 Locust 运行性能测试。
实际有点差别 一个是 locust 一个是 httprunner 的 locusts 多了个 s
