ubuntu16.04.3 python 多版本改造与 HttpRunner 部署

启动 demo server

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
Collecting 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

编辑测试脚本

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

Running tests...

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

1.使用 postman 的 Postman Interceptor 来捕获请求

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.

2. 使用新版 firefox57.0.1 提供的 web 开发者工具

已经替代 firebug

3.使用 charles

https://www.charlesproxy.com/

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...
----------------------------------------------------------------------

同时有结果报告在脚本同目录下。

locusts 接口性能测试

http://httprunner.readthedocs.io/en/latest/load-test.html
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
