  • postman常用断言

    一、如何添加断言

    二、常用断言

    1.最基本的返回验证

    //1.验证返回状态码是否是200
    pm.test("Status code is 200", function () {
        pm.response.to.have.status(200);
    });
    //2.验证返回body内是否含有某个值
    pm.test("Body matches string", function () {
        pm.expect(pm.response.text()).to.include("string_you_want_to_search");
    });
    //3.验证某个返回值是否是100
    pm.test("Your test name", function () {
        var jsonData = pm.response.json();
        pm.expect(jsonData.value).to.eql(100);
    });
    //验证返回body中是否含有某个字符串
    pm.test("Body is correct", function () {
        pm.response.to.have.body("response_body_string");
    });
    //验证返回头类型
    pm.test("Content-Type is present", function () {
        pm.response.to.have.header("Content-Type");
    });
    //验证请求时长是否小于200ms
    pm.test("Response time is less than 200ms", function () {
        pm.expect(pm.response.responseTime).to.be.below(200);
    });
    //验证返回码是否为200
    pm.test("Successful POST request", function () {
        pm.expect(pm.response.code).to.be.oneOf([201,202]);
    });
    //验证返回数据中是否包含某个字符串
    pm.test("Status code name has string", function () {
        pm.response.to.have.status("Created");
    });
    //验证json数据的微小验证器
    var jsonObject = xml2Json(responseBody);
    var schema = {
      "items": {
        "type": "boolean"
      }
    };
    var data1 = [true, false];
    var data2 = [true, 123];
    pm.test('Schema is valid', function() {
      pm.expect(tv4.validate(data1, schema)).to.be.true;
      pm.expect(tv4.validate(data2, schema)).to.be.true;
    });

    三、实例1:对返回的json数据中的key对应的value做校验:

    返回数据如下:

    {
        "resultStatus": 1,
        "status": 1,
        "data": [
            {
                "orderNum": null,
                "categoryId": null,
                "dataList": [
                    {
                        "jump": {
                            "type": 41,
                            "value": {
                                "value": {
                                    "dataType": 1,
                                    "albumId": "10036379",
                                    "tvCopyright": 1,
                                    "src": 1
                                },
                                "type": 1
                            }
                        }
                    }
                ]
            }

    添加断言校验

    tests["Status code is 200"] = responseCode.code === 200
    
    pm.test("验证服务器返回 src 值为:1", function () {
        var jsonData = pm.response.json();
        var jsonDicData = jsonData.data[0].dataList[0].jump.value.value.src;
        pm.expect(jsonDicData).to.eql(1);
    });
    pm.test("验证服务器返回 type 值为:41", function () {
        var jsonData = pm.response.json();
        var jsonDicData = jsonData.data[0].dataList[0].jump.type;
        pm.expect(jsonDicData).to.eql(41);
    });
    pm.test("验证服务器返回 type 值为:1", function () {
        var jsonData = pm.response.json();
        var jsonDicData = jsonData.data[0].dataList[0].jump.value.type;
        pm.expect(jsonDicData).to.eql(1);
    });

    实例2:

    返回值:

    {
        "data": {
            "beginTime": 1604567324000,
            "endTime": 1606727324000,
            "examRemainCount": 2,
            "examId": 113
        },
        "timestamp": 1606466585273,
        "code": "SUCCESS",
        "msg": "成功",
        "success": true
    }

    断言:

    // tests["字符串匹配——成功"] = responseBody.has("成功");
    tests["Status code is 200"] = responseCode.code === 200
    
    pm.test("验证examid值为113",function(){
        var jd=pm.response.json();
        var examId=jd.data.examId
        pm.expect(examId).to.eql(113)
    })
    pm.test("验证msg值为成功",function(){
        var jd=pm.response.json();
        var msg=jd.msg
        pm.expect(msg).to.equal('成功')
    })

    pm.environment.set("obj", JSON.stringify(obj));
    

      

    Getting an environment variable (获取环境变量)

    pm.environment.get("variable_key");
    

      

    Getting an environment variable (whose value is a stringified object)  获取一个环境变量(其值是一个字符串化的对象)

    // 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.environment.unset("variable_key");
    

      

    Set a global variable (设置一个全局变量)

    pm.globals.set("variable_key", "variable_value");
    

      

    Get a global variable (获取一个全局变量)

    pm.globals.get("variable_key");
    

      

    Clear a global variable (清除全局变量)

    pm.globals.unset("variable_key");
    

      

    Get a variable (获取一个变量)

    该函数在全局变量和活动环境中搜索变量。

    pm.variables.get("variable_key");
    

      

    Check if response body contains a string (检查响应主体是否包含字符串)

    pm.test("Body matches string", function () {
        pm.expect(pm.response.text()).to.include("string_you_want_to_search");
    });
    

      

    Check if response body is equal to a string (检查响应主体是否等于一个字符串)

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

      

    Check for a JSON value (检查JSON值

    pm.test("Your test name", function () {
        var jsonData = pm.response.json();
        pm.expect(jsonData.value).to.eql(100);
    });
    

      

    Content-Type is present (内容类型存在

    pm.test("Content-Type is present", function () {
        pm.response.to.have.header("Content-Type");
    });
    

      

    Response time is less than 200ms (响应时间小于200ms

        pm.expect(pm.response.responseTime).to.be.below(200);
    });
    

      

    Status code is 200 (状态码是200

    pm.test("Status code is 200", function () {
        pm.response.to.have.status(200);
    });
    

      

    Code name contains a string (代码名称包含一个字符串

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

      

    Successful POST request status code (成功的POST请求状态码

    pm.test("Successful POST request", function () {
        pm.expect(pm.response.code).to.be.oneOf([201,202]);
    });
    

      

    Use TinyValidator for JSON data (对于JSON数据使用TinyValidator

    var schema = {
     "items": {
     "type": "boolean"
     }
    };
    var data1 = [true, false];
    var data2 = [true, 123];
    
    pm.test('Schema is valid', function() {
      pm.expect(tv4.validate(data1, schema)).to.be.true;
      pm.expect(tv4.validate(data2, schema)).to.be.true;
    });
    

      

    Decode base64 encoded data (解码base64编码的数据

    var intermediate,
    	base64Content, // assume this has a base64 encoded value
    	rawContent = base64Content.slice('data:application/octet-stream;base64,'.length);
    
    intermediate = CryptoJS.enc.Base64.parse(base64content); // CryptoJS is an inbuilt object, documented here: https://www.npmjs.com/package/crypto-js
    pm.test('Contents are valid', function() {
      pm.expect(CryptoJS.enc.Utf8.stringify(intermediate)).to.be.true; // a check for non-emptiness
    });
    

      

    Send an asynchronous request (发送异步请求

    该功能既可以作为预先请求,也可以作为测试脚本使用。

    pm.sendRequest("https://postman-echo.com/get", function (err, response) {
        console.log(response.json());
    });
    

      

    Convert XML body to a JSON object (将XML正文转换为JSON对象

    var jsonObject = xml2Json(responseBody);
