【郑州校区】数据驱动实战二
目标1. 掌握数据驱动的开发流程 2. 掌握如何读取JSON数据文件 3. 巩固PO模式 1. 案例 对TPshop网站的登录模块进行单元测试
1.1 实现步骤 1. 编写测试用例 2. 采用PO模式的分层思想对页面进行封装 3. 编写测试脚本 4. 定义数据文件，实现参数化
1.2 用例设计
1.3 数据文件 [AppleScript] 纯文本查看 复制代码
{
"login_username_is_null": { "username": "", "password": "123456",
"code": "8888",
"is_success": false, "expect": "用户名不能为空"
},
"login_password_is_null": { "username": "13012345678", "password": "",
"code": "8888",
"is_success": false, "expect": "密码不能为空"
},
"login_password_is_error": { "username": "13012345678", "password": "error",
"code": "8888",

"password": "123456",
"code": "8888",
"is_success": true, "expect": "我的账户"
