3.检查response body中是否包含某个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)
14.JSON.parse()和JSON.stringify()
postman常用方法集合:
1.设置环境变量
postman.setEnvironmentVariable("key", "value");
pm.environment.set("key", "value");//postman 5.0以上版本设置环境变量的方法
2.设置全局变量
postman.setGlobalVariable("key", "value");
pm.globals.set("variable_key", "variable_value");//postman 5.0以上版本设置全局变量方法
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");
});//5.0以上版本方法
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");
//5.0以上版本方法
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
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);
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()
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"
15.判断字段值是否为空typeof()
var Jsondata = JSON.parse(responseBody);
if( typeof(Jsondata.data) != "undefined" )
