name: 登录接口
variables:
    username: ${ENV(USERNAME)}
    password: ${ENV(PASSWORD)}
request:
    url: http://127.0.0.1:8000/user/login/
    method: POST
    headers:
        Content-Type: "application/json"
    json:
        username: $username
        password: $password
validate:
    - eq: ["status_code", 200]
extract:
    - uname: content.username

可以修改variables定义变量，导入环境变量作为值

request中可以使用$变量名来获取variables区域下的变量

调用函数

可以调用debugtalk.py中的函数

例如在该文件中添加

1

3
def get_user_agent():
    user_agents = ['Mozilla/5.0 AAA', 'Mozilla/5.0 BBB', 'Mozilla/5.0 CCC']
    return random.choice(user_agents)

name: 登录接口
variables:
    username: ${ENV(USERNAME)}
    password: ${ENV(PASSWORD)}
request:
    url: http://127.0.0.1:8000/user/login/
    method: POST
    headers:
        Content-Type: "application/json"
        User-Agent: ${get_user_agent()}
    json:
        username: $username
        password: $password
validate:
    - eq: ["status_code", 200]

使用${get_user_agent()}

这样就可以动态的使用User-Agent

校验

可以用的响应属性：

  • available
  • response
  • status_code
  • cookies
  • elapsed
  • headers
  • content
  • text
  • json
  • encoding
  • ok
  • reason
  • url
1
- eq: ["headers.Content-Type", "application/json"]
1
- {check: "headers.Content-Type",comparator: "eq",expect: "application/json"}

上面两种写法效果一致

  • check：指定断言哪一个字段（实际值）

python3.7/site-packages/httprunner/built_in.py

  • comparator：指定断言的规则
    • eq 等于
    • lt小于
    • lte
    • gt大于
    • gte
    • str_eq
    • len_eq长度等于
    • len_gt
    • contains 包含

config:
    name: "登录接口测试"
    variables:
        device_sn: "ABC"
        username: ${ENV(USERNAME)}
        password: ${ENV(PASSWORD)}
    base_url: "http://127.0.0.1:8000"

teststeps:
-
    name: 登录
    api: api/login.yml
    validate:
        - eq: ["status_code", 200]

继承api/login.yml会与本区域定义的validate合并覆盖

一般api路径下的断言只进行基础类型的断言例如status_code

testcases会进行其他的断言

方式一：使用yaml

testsuites/api_testsuite.yml

config:
    name: 接口测试套件
    base_url: "http://127.0.0.1:8000"

testcases:
-
    name: 登录接口
    testcase: testcases/login.yml
    parameters:
        # 方式一
        # 多个具有关联性的参数，需要将其定义在一起，并且采用短横线进行连接
        - title-username-password-status_code-contain_msg:
              - ["正常登录", "zhongxin", "123456", 200, "token"]
              - ["密码错误", "zhongxin", "1234567", 400, "non_field_errors"]
              - ["账号错误", "zhongxin11", "123456", 400, "non_field_errors"]
              - ["用户名为空", "", "123456", 400, "username"]
              - ["密码为空", "zhongxin", "", 400, "password"]

运行

1
$ hrun testsuites/api_testsuite.yml

查看报告

报告

方式二：读取文件

新建一个csv文件

title,username,password,status_code,contain_msg
正常登录, zhongxin, 123456, 200, token
密码错误, zhongxin, 1234567, 400, non_field_errors
账号错误, zhongxin11, 123456, 400, non_field_errors
用户名为空, , 123456, 400, username
密码为空, zhongxin, , 400, password
1
- title-username-password-status_code-contain_msg: ${P(datas/accounts.csv)}

方式三：使用函数

在debugtalk.py添加

def get_accounts():
    accounts = [
        {"title": "正常登录", "username": "zhongxin", "password": "123456", "status_code": 200, "contain_msg": "token"},
        {"title": "密码错误", "username": "zhongxin", "password": "1234567", "status_code": 400, "contain_msg": "non_field_errors"},
    ]
    return accounts
1
- title-username-password-status_code-contain_msg: ${get_accounts()}

使用py文件调用httprunner
