postman断言

较旧的写作邮差测试风格

较旧的Postman测试编写风格依赖于特殊tests对象的设置值。您可以为对象中的元素设置描述性键，然后说明它是真还是假。例如，tests["Body contains user_id"] = responsebody.has("user_id");将检查响应主体是否包含user_id字符串。

您可以根据需要添加任意数量的密钥，具体取决于您要测试的内容。您可以在“ 测试”选项卡下的响应查看器中查看测试结果。选项卡标题显示传递了多少测试，并在此处列出了您在tests变量中设置的键。如果值的计算结果为true，则测试通过。

设置环境变量

postman.setEnvironmentVariable("key", "value");

将嵌套对象设置为环境变量

var array = [1, 2, 3, 4];
postman.setEnvironmentVariable("array", JSON.stringify(array, null, 2));

var obj = { a: [1, 2, 3, 4], b: { c: 'val' } };
postman.setEnvironmentVariable("obj", JSON.stringify(obj));

获取环境变量

postman.getEnvironmentVariable("key");

获取环境变量（其值是字符串化对象）

// These statements should be wrapped in a try-catch block if the data is coming from an unknown source.

var array = JSON.parse(postman.getEnvironmentVariable("array"));
var obj = JSON.parse(postman.getEnvironmentVariable("obj"));

清除环境变量

postman.clearEnvironmentVariable("key");

设置全局变量

postman.setGlobalVariable("key", "value");

获取全局变量

postman.getGlobalVariable("key");

清除全局变量

postman.clearGlobalVariable("key");

检查响应主体是否包含字符串

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

将XML主体转换为JSON对象

var jsonObject = xml2Json(responseBody);

检查响应主体是否等于字符串

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

检查JSON值

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

存在Content-Type（不区分大小写的检查）

tests["Content-Type is present"] = postman.getResponseHeader("Content-Type"); //Note: the getResponseHeader() method returns the header value, if it exists.

内容类型存在（区分大小写）

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

响应时间小于200毫秒

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

响应时间在特定范围内（包含下限，上限不包括）

tests["Response time is acceptable"] = _.inRange(responseTime, 100, 1001); // _ is the inbuilt Lodash v3.10.1 object, documented at https://lodash.com/docs/3.10.1

状态代码是200

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

代码名称包含一个字符串

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

成功的POST请求状态代码

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

使用TinyValidator获取JSON数据

var schema = {
 "items": {
 "type": "boolean"
 }
};
var data1 = [true, false];
var data2 = [true, 123];

tests["Valid Data1"] = tv4.validate(data1, schema);
tests["Valid Data2"] = tv4.validate(data2, schema);
console.log("Validation failed: ", tv4.error);

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
tests["Contents are valid"] = CryptoJS.enc.Utf8.stringify(intermediate); // a check for non-emptin
