Postman参数化

文章目录

一、没有使用参数化

请求url:

https://postman-echo.com/post

json请求体：

{"user":"admin","pwd":"abc1234"}

断言代码：

pm.test("用户名密码正常，登陆成功",function(){var jsonData = pm.response.json();
    pm.expect(jsonData.data.user).to.eql("admin");
    pm.expect(jsonData.data.pwd).to.eql("abc1234");});

• 没有参数化，如果有多个用例，即需在postman设置多个请求，重复率高

二、参数化

• 参数化支持的文件格式：json、csv
• 这里以json格式举例
• 注意：- 保存为UTF-8编码格式- 一个测试用例一条数据- - 一条数据内容一般包含 - 用例名称- 测试数据- 预期结果-

1. 测试数据部分字段参数化

1.1 参数化文件login1.json内容如下：

[{"case_name":"用户名密码正常，登陆成功","username":"admin","password":"abc1234","expect_user":"admin","expect_pwd":"abc1234"},{"case_name":"用户名错误，登陆失败","username":"adminxxx","password":"abc1234","expect_user":"adminxxx","expect_pwd":"abc1234"},{"case_name":"密码错误，登陆失败","username":"admin","password":"abc1234mike","expect_user":"admin","expect_pwd":"abc1234mike"}]

1.2 Postman设置

json请求体：

{"user":"{{username}}","pwd":"{{password}}"}

断言代码：

pm.test(data.case_name,function(){var jsonData = pm.response.json();
    pm.expect(jsonData.data.user).to.eql(data.expect_user);
    pm.expect(jsonData.data.pwd).to.eql(data.expect_pwd);});

1.3 关联文件，发送请求

• 注意：引用参数化文件不能直接点send按钮发送请求
• 需通过批量运行run按钮选择文件，再运行

2. 请求体参数化：请求体作为字符串处理

• 处理方式- 最外层加上双引号- 里面本身的双引号左边加上反斜杠-

2.1 参数化文件login2.json内容如下：

[{"case_name":"用户名密码正常，登陆成功","body":"{\"user\": \"admin\", \"pwd\": \"abc1234\"}","expect_user":"admin","expect_pwd":"abc1234"},{"case_name":"用户名错误，登陆失败","body":"{\"user\": \"adminxxx\", \"pwd\": \"abc1234\"}","expect_user":"adminxxx","expect_pwd":"abc1234"},{"case_name":"密码错误，登陆失败","body":"{\"user\": \"admin\", \"pwd\": \"abc1234mike\"}","expect_user":"admin","expect_pwd":"abc1234mike"}]

2.2 Postman设置

json请求体：

{{body}}

• 断言设置，关联文件，发送请求，和上面一样，这里不再重复截图

3. 请求体参数化：通过Pre-request Scrip预处理

3.1 参数化文件login3.json内容如下

[{"case_name":"用户名密码正常，登陆成功","body":{"user":"admin","pwd":"abc1234"},"expect_user":"admin","expect_pwd":"abc1234"},{"case_name":"用户名错误，登陆失败","body":{"user":"adminxxx","pwd":"abc1234"},"expect_user":"adminxxx","expect_pwd":"abc1234"},{"case_name":"密码错误，登陆失败","body":{"user":"admin","pwd":"abc1234mike"},"expect_user":"admin","expect_pwd":"abc1234mike"}]

3.2 Pre-request Scrip预处理

// json转string
body_value =JSON.stringify(data.body);// 设置全局变量
pm.globals.set("body_value", body_value);

3.3 json请求体处理

json请求体：

{{body_value}}
