  • PostmanTests模块测试方法记录

    用Postman的时候大多数测试结果是可以用Tests模块的测试方法来代替人工检查的,测试方法本质上是JavaScript代码,我们可以通过运行测试用例(测试脚本是在发送请求之后并且从服务器接收到响应时执行),观察结果是“PASS”还是“FAIL”就能判断测试结果:

    在此记录一些常用方法备忘(当遇到需要判断返回值为A或B的时候,使用“||”符号):

    1.设置环境变量

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

    2.将一个嵌套的对象设置为一个环境变量

    var array = [1, 2, 3, 4];

    pm.environment.set("array", JSON.stringify(array, null, 2));

    var obj = { a: [1, 2, 3, 4], b: { c: 'val' } };

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

    3.获得一个环境变量

    pm.environment.get("variable_key");

    4.获得一个环境变量(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"));

    5.清除一个环境变量

    pm.environment.unset("variable_key");

    6.设置一个全局变量

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

    7.获取一个全局变量

    pm.globals.get("variable_key");

    8.清除一个全局变量

    pm.globals.unset("variable_key");

    9.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");

    10.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");

    });

    11.检查响应体是否等于字符串

    pm.test("Body is correct", function () {

    pm.response.to.have.body("response_body_string");
    });

    12.检查JSON值

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

    13.Content-Type 存在

    pm.test("Content-Type is present", function () {

    pm.response.to.have.header("Content-Type");
    });

    14.返回时间少于200ms

    pm.test("Response time is less than 200ms", function () {

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

    });

    15.状态码是200

    pm.test("Status code is 200", function () {

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

    });

    16.代码名包含一个字符串

    pm.test("Status code name has string", function () {

    pm.response.to.have.status("Created");

    });

    17.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]);

    });

    18.为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;

    });

    19.解码base64编码数据

    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

    });

    20.发送异步请求
    此函数可作为预请求和测试脚本使用

    pm.sendRequest("https://postman-echo.com/get", function (err, response) {

    console.log(response.json());

    });

    21.将XML主体转换为JSON对象

    var jsonObject = xml2Json(responseBody);

    -----------------------------------------------------------------------------------------------------------------------------

    1. 清除一个全局变量
    Clear a global variable
    对应脚本:
    postman.clearGlobalVariable("variable_key");
    参数:需要清除的变量的key

    2.清除一个环境变量
    Clear an environment variable
    对应脚本:
    postman.clearEnvironmentVariable("variable_key");
    参数:需要清除的环境变量的key

    3.response包含内容
    Response body:Contains string
    对应脚本:
    tests["Body matches string"] =responseBody.has("string_you_want_to_search");
    参数:预期内容

    4.将xml格式的response转换成son格式
    Response body:Convert XML body to a JSON Object
    对应脚本:
    var jsonObject = xml2Json(responseBody);
    参数:(默认不需要设置参数,为接口的response)需要转换的xml

    5.response等于预期内容
    Response body:Is equal to a string
    对应脚本:
    tests["Body is correct"] = responseBody === "response_body_string";
    参数:预期response

    6.json解析key的值进行校验
    Response body:JSON value check
    对应脚本:
    tests["Args key contains argument passed as url parameter"] = 'test' in responseJSON.args
    参数:test替换被测的值,args替换被测的key

    7.检查response的header信息是否有被测字段
    Response headers:Content-Type header check
    对应脚本:
    tests["Content-Type is present"] = postman.getResponseHeader("Content-Type");
    参数:预期header

    8.响应时间判断
    Response time is less than 200ms
    对应脚本:
    tests["Response time is less than 200ms"] = responseTime < 200;
    参数:响应时间

    9.设置全局变量
    Set an global variable
    对应脚本:
    postman.setGlobalVariable("variable_key", "variable_value");

    对应脚本:
    tests["Status code is 200"] = responseCode.code != 400;
    参数:状态码

    12.检查code name 是否包含内容
    Status code:Code name has string
    对应脚本:
    tests["Status code name has string"] = responseCode.name.has("Created");

    13.成功的post请求
    Status code:Successful POST request
    对应脚本:
    tests["Successful POST request"] = responseCode.code === 201 || responseCode.code === 202;

    14.微小验证器
    Use Tiny Validator for JSON data
    对应脚本:
    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);
    参数:可以修改items里面的键值对来对应验证json的参数
