测试开发进阶(三十二)

开启跨域

安装django-cors-headers

1. 添加应用

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'corsheaders',
    'user.apps.UserConfig',
]

2.添加中间件

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    # 'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

3. 添加白名单

CORS_ORIGIN_ALLOW_ALL = True  # 所有域名都允许，默认False
# CORS_ORIGIN_WHITELIST = [
#     # 指定可以访问后端的域名
#     "http://127.0.0.1:8080",
#     "http://localhost:8080",
# ]
CORS_ALLOW_CREDENTIALS = True  # 语序跨域时携带Cookie，默认False

HttpRunner

接口测试有哪些方法

• 工具：Postman
• 使用代码创建接口测试框架

用例数据存放在哪？excel

unittest + ddt 数据驱动，测数据与测试代码分离

日志器

配置文件

数据库校验：pymysql

发起请求：request

参数化：正则匹配

接口依赖：动态创建类属性的方式来处理

Jenkins实现持续集成

HttpRunner 将上述框架进行封装，几乎可以零代码，高效率的进行测试

安装

$ pip install httprunner

创建工程

$ hrun --startproject httprunner_learn

最小单元

新建api/login.yml

name: 登录接口
variables:
    var1: value1
    var2: value2
request:
    url: http://127.0.0.1:8000/user/login/
    method: POST
    headers:
        Content-Type: "application/json"
    json:
        username: zhongxin
        password: 123456
validate:
    - eq: ["status_code", 200]

测试

zhongxindeMacBook-Pro:httprunner_learn zhongxin$ hrun api/login.ym

查看报告

使用环境变量

.env文件:${ENV(USERNAME)}

USERNAME=zhongxin
PASSWORD=123456

name: 登录接口
variables:
    var1: value1
    var2: value2
request:
    url: http://127.0.0.1:8000/user/login/
    method: POST
    headers:
        Content-Type: "application/json"
    json:
        username: ${ENV(USERNAME)}
        password: ${ENV(PASSWORD)}
validate:
    - eq: ["status_code", 200]
