postman tests 方法集合

postmanTests可设置/清除变量, 对比返回值信息。常用方法集合汇总如下:

1.设置环境变量

postman.setEnvironmentVariable("key", "value");
pm.environment.get("key", "value");

2.设置全局变量

postman.setGlobalVariable("key", "value");
pm.globals.set("variable_key", "variable_value");

3.检查response body中是否包含某个string

tests["Body matches string"] = responseBody.has("string_you_want_to_search");

pm.test("Body is correct", function () {
    pm.response.to.have.body("response_body_string");
});

4.检测JSON中的某个值是否等于预期的值

var data = JSON.parse(responseBody);
tests["Your test name"] = data.value === 100;

JSON.parse()方法,把json字符串转化为对象。parse()会进行json格式的检查是一个安全的函数。 

如:检查json中某个数组元素的个数(这里检测programs的长度)

var data = JSON.parse(responseBody);
tests["program's lenght"] = data.programs.length === 5;

5.转换XML body为JSON对象

var jsonObject = xml2Json(responseBody);

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

6.检查response body是否与某个string相等

7.测试response Headers中的某个元素是否存在(如:Content-Type)

//getResponseHeader()方法会返回header的值,如果该值存在
tests["Content-Type is present"] = postman.getResponseHeader("Content-Type"); 

tests["Content-Type is present"] = responseHeaders.hasOwnProperty("Content-Type");

上面的方法,不区分大小写。下面的方法,要区分大小写。 

8.验证Status code的值

tests["Status code is 200"] = responseCode.code === 200;

pm.test("Status code is 200", function () {
pm.response.to.have.status(200);
});//5.0以上版本方法

9.验证Response time是否小于某个值

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

//5.0以上版本方法
pm.test("Response time is less than 200ms", function () {
    pm.expect(pm.response.responseTime).to.be.below(200);
});

10.name是否包含某个值

tests["Status code name has string"] = responseCode.name.has("Created");

pm.test("Status code name has string", function () {
    pm.response.to.have.status("Created");
});

11.POST 请求的状态响应码是否是某个值

tests["Successful POST request"] = responseCode.code === 201 || responseCode.code === 202;

//5.0以上版本方法
pm.test("Successful POST request", function () {
    pm.expect(pm.response.code).to.be.oneOf([201,202]);
});

12.很小的JSON数据验证器

复制代码
var schema = {
"items": {
"type": "boolean"
}
};
var data1 = [true, false];
var data2 = [true, 123];
console.log(tv4.error);
tests["Valid Data1"] = tv4.validate(data1, schema);
tests["Valid Data2"] = tv4.validate(data2, schema);
复制代码
 
13.获取request.data值:
var Json = JSON.parse(request.data); 
  • data {object}:
    this is a dictionary of form data for the request. (request.data["key"]=="value")

  • headers {object}:
    this is a dictionary of headers for the request (request.headers["key"]=="value")

  • method {string}:
    GET/POST/PUT etc.

  • url {string}:
    the url for the request.

假设requestBody中有"version":"1.0";这个值,如果想获取到version的value值,代码如下
var Json = JSON.parse(request.data); 
var version = Json["version"];

14.JSON.parse()和JSON.stringify()

复制代码

JSON.parse()【从一个字符串中解析出json对象】
JSON.stringify()【从一个对象中解析出字符串】

var data={name:'goatling'}
JSON.parse(data)
结果是:
'{"name":"goatling"}'

JSON.stringify(data)
结果是:
name:"goatling"
 
复制代码

15.判断字段值是否为空typeof()

var Jsondata = JSON.parse(responseBody);
if( typeof(Jsondata.data) != "undefined" )
