断言就是输入代码：实际结果和预期结果的对比
postman中的请求tests右侧封装了各种断言类型，只需要选择，自动带出断言代码，替换参数即可
断言HTTP响应状态码为200
点击testresults处查看断言实际情况
断言响应内容中包含某值
解析并断言响应内容
断言响应时间是否小于200ms
postman常见断言方法介绍：

var array = [1, 2, 3, 4];pm.environment.set("array", JSON.stringify(array, null, 2));var obj = { a: [1, 2, 3, 4], b: { c: 'val' } };pm.environment.set("obj", JSON.stringify(obj)); |
Getting an environment variable (获取环境变量)
|

|
pm.environment.get("variable_key"); |

// These statements should be wrapped in a try-catch block if the data is coming from an unknown source.var array = JSON.parse(pm.environment.get("array"));var obj = JSON.parse(pm.environment.get("obj")); |
Clear an environment variable (清除一个环境变量)
|

|
pm.globals.unset("variable_key"); |
