postman tests常用方法
postman常用方法集合:
1.设置环境变量
postman.setEnvironmentVariable("key", "value"); pm.environment.get("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" )
