做测试的同学,我相信每个人都知道断言,就是结果和预期对比,如果一致,则用例通过,如果不一致,断言失败,用例失败。那么上面这个接口我们如何用postman来进行断言呢?也很简单,用到postman tests 这个模块。
那么上面的接口我们如何断言呢?很简单,从响应内容做断言。比如我们可以断言 id=90,url = "http://www.v2ex.com/go/python",状态码等于200
我们在tests输入框填写:
postman常见断言方法介绍:
Setting an environment variable (设置一个环境变量)
1 | pm.environment.set("variable_key", "variable_value"); |
Setting a nested object as an environment variable (将嵌套对象设置为环境变量)
1 2 3 4 5 | 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)); |
Getting an environment variable (获取环境变量)
1 | 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)
1 2 3 4 | // 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)
1 | pm.environment.unset("variable_key"); |
Set a global variable (设置一个全局变量)
1 | pm.globals.set("variable_key", "variable_value"); |
Get a global variable (获取一个全局变量)
1 | pm.globals.get("variable_key"); |
Clear a global variable (清除全局变量)
1 | 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。
1 | 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)
1 2 3 | 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)
1 2 3 | pm.test("Body is correct", function () { pm.response.to.have.body("response_body_string"); }); |
Check for a JSON value (检查JSON值)
1 2 3 4 | 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)
1 2 3 | 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)
1 2 3 | pm.test("Response time is less than 200ms", function () { pm.expect(pm.response.responseTime).to.be.below(200); }); |
Status code is 200 (状态码是200)
1 2 3 | 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)
1 2 3 | 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)
1 2 3 | 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)
1 2 3 4 5 6 7 8 9 10 11 12 | 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)
1 2 3 4 5 6 7 8 | 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。
1 2 3 | 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)
1 | var jsonObject = xml2Json(responseBody); |
