httprunner使用02参数化.env环境变量调用debugtalk.py文件的函数关联validate 断言

Posted 2020-12-10 xiaoshijie

一、参数化

1）创建套件

config:
  name: 测试套件

testcases:
#  - name: test_demo_04
#    testcase: testcases/20200610/test_demo_04.yml
#    parameters:
#      search_word: [‘天天向上‘,‘12306‘,‘newdream‘]
  - name: test_demo_04
    testcase: testcases/tasks/demo_05.yml
    parameters:
      tag_name: [‘test01‘,‘test02‘,‘test03‘,‘test04‘,‘test05‘,‘test06‘,‘test07‘,‘test08‘,‘test09‘,‘test10‘]

2）参数化使用： $ 参数名（如：$tag_name）

- config:
    name: "创建标签"
    base_url: ${ENV(URL)}
    variables:
      - token: ${get_token()}
- test:
    name: "create tag"
    request:
      url: /cgi-bin/tags/create
      params:
        access_token: $token
      method: POST
      json: {   "tag" : {     "name" : $tag_name  } }
#    {"tag":{"id":198,"name":"2020061302"}}
    validate:
      - gt: [content.tag.id,0]

 3）执行套件，查看报告

使用命令执行：hrun 套件路径/文件名.yml

 二、.env环境变量，调用debugtalk.py文件的函数

1）右击项目名，新建文件名为【.env】的文件，配置环境变量

 2）右击项目名，新建py文件，名为【debugtalk.py】，自定义函数（如：get_token()函数）

import requests

def get_token():

    get_param_data={
        ‘grant_type‘:‘client_credential‘,
        ‘appid‘:‘appid‘,
        ‘secret‘:‘secret‘
    }

    response = requests.get(‘https://api.weixin.qq.com/cgi-bin/token‘,get_param_data)
    return response.json()[‘access_token‘]

 3）yml文件调用环境变量（$ENV(变量名)）和 get_token()函数（$函数名）

- config:
    name: "删除标签"
    base_url: ${ENV(URL)}
    variables:
      - token: ${get_token()}
- test:
      name: "delete tag"
      request:
          url: "/cgi-bin/tags/delete"
          headers:
            User-Agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36"
            Content-Type: application/json
          method: POST
          params:
              access_token: $token
          json: {  "tag":{ "id" : 190 } }
      validate:
          - eq: [content.errcode,0]

 三、关联： $参数名

# httprunner关联
- config:
    name: "验证能否获取token值"
    base_url: "https://api.weixin.qq.com"

- test:
    name: "get access_token"
    request:
      url: "/cgi-bin/token"
      method: GET
      params:
        grant_type: "client_credential"
        appid: "xxx"
        secret: "xxx"
    extract:
      - access_token: content.access_token
    validate:
      - eq: ["status_code",200]
      - eq: [content.expires_in,7200] #content响应正文

- test:
    name: "delete tag"
    request:
      url: "/cgi-bin/tags/delete"
      method: POST
      params:
         access_token: $access_token
      json: {   "tag":{ "id" : 192   } }
    validate:
      - eq: [content.errcode,0]

 四、断言

1）validate支持两种格式：

"comparator_name": [check_item, expect_value]

{"check": check_item, "comparator": comparator_name, "expect": expect_value} hooks 

如：

validate:

  - eq: [content.errcode,0]

  - {"check":$reason,"comparator":"str_eq","expect":"OK"} #检查说明，检查方式，期望结果

 

 2）支持的校验器

源码

def get_uniform_comparator(comparator):
    """ convert comparator alias to uniform name
    """
    if comparator in ["eq", "equals", "==", "is"]:    ##等于
        return "equals"
    elif comparator in ["lt", "less_than"]:     ##小于
        return "less_than"
    elif comparator in ["le", "less_than_or_equals"]:  ##小于等于
        return "less_than_or_equals"
    elif comparator in ["gt", "greater_than"]:   ##大于
        return "greater_than"
    elif comparator in ["ge", "greater_than_or_equals"]:     ##大于等于
        return "greater_than_or_equals"
    elif comparator in ["ne", "not_equals"]:     ##不等于
        return "not_equals"
    elif comparator in ["str_eq", "string_equals"]:  ##字符串相等
        return "string_equals"
    elif comparator in ["len_eq", "length_equals", "count_eq"]:  ##长度相等
        return "length_equals"
    elif comparator in ["len_gt", "count_gt", "length_greater_than", "count_greater_than"]:  ##长度大于
        return "length_greater_than"
    elif comparator in ["len_ge", "count_ge", "length_greater_than_or_equals",    ##长度大于等于
        "count_greater_than_or_equals"]:
        return "length_greater_than_or_equals"
    elif comparator in ["len_lt", "count_lt", "length_less_than", "count_less_than"]:  ##长度小于
        return "length_less_than"
    elif comparator in ["len_le", "count_le", "length_less_than_or_equals",    ##长度小于等于
        "count_less_than_or_equals"]:
        return "length_less_than_or_equals"
    else:
        return comparator            ##自定义

 

以访问百度首页举例（其中断言全部通过）：
