Postman(day2)

1、Postman的test功能---运行在sandbox中

设置全局变量 ：（用例中好多地方都用到的）

postman.clearGlobalVariable("variable_key");

设置环境变量:(比如ip设置)

postman.clearEnvironmentVariable("variable_key");

拿到并处理请求的响应:

tests["Body is correct"]=responseBody==="response_body_string";

定义测试检查点和断言(判断预期结果与实际结果之间的差异):

tests["Response time is less than 200ms"]=reponseTime<200;

tests["state code is 200"]=reponseCode.code===200;

var jsondata = JSON.parse(reponseBody)  //将响应的json字符串转为javascript对象

tests["num is 10"]=jsondata.length===10;

2、Http响应的构成：

状态行(状态码和简单的一句描述)

Headers

Body

3、postman的Sandbox

是javascript执行环境，在postman运行一些javascript代码的地方

• 公共库
• 环境变量与全局变量
• 动态变量
• 操作cookie
• 获取和查看请求及响应
• 读取数据文件

sandbox 的 API:

pm.test("状态返回200",function(){

　　pm.expect(pm.response).to.have.status(200);

pm.expect(pm)

})

Response Assertion API in test scripts

• pm.response.to.have.status(code:Number)
• pm.response.to.have.status(reason:String)
• pm.response.to.have.header(key:String)
• pm.response.to.have.header(key:String, optionalValue:String)
• pm.response.to.have.body()
• pm.response.to.have.body(optionalValue:String)
• pm.response.to.have.body(optionalValue:RegExp)
• pm.response.to.have.jsonBody()
• pm.response.to.have.jsonBody(optionalExpectEqual:Object)
• pm.response.to.have.jsonBody(optionalExpectPath:String)
• pm.response.to.have.jsonBody(optionalExpectPath:String, optionalValue

pm.response.to.be.*

The properties inside the pm.response.to.be object allows you to easily assert a set of pre-defined rules.

• pm.response.to.be.info
• Checks 1XX status code

• pm.response.to.be.success
• Checks 2XX status code

• pm.response.to.be.redirection
• Checks 3XX status code

• pm.response.to.be.clientError
• Checks 4XX status code

• pm.response.to.be.serverError
• Checks 5XX

• pm.response.to.be.error
• Checks 4XX or 5XX

• pm.response.to.be.ok
• Status code must be 200

• pm.response.to.be.accepted
• Status code must be 202

• pm.response.to.be.badRequest
• Status code must be 400

• pm.response.to.be.unauthorized
• Status code must be 401

• pm.response.to.be.forbidden
• Status code 403

• pm.response.to.be.notFound

• Status code of response is checked to be 404

• pm.response.to.be.rateLimited
• Checks whether response status code is 429
