Postman 测试自动化 - 验证 json 数组响应

Question

我有一个简单的 api GET 请求，响应正文如下所示。我正在使用 Postman API 自动化，我想验证响应并使用 Postman 测试检查是否满足以下条件。

1. 响应数组大小应始终为 2
2. 在每个数组项中，“build.time”值应为日期时间。
3. 在每个数组项中，“build.artifact”值应等于“main_component”。
4. 第一个数组项的“build.name”值应等于“web app”
5. 第二个数组项的“build.name”值应该等于“后端”。

[
    {
        "build.time": "2020-01-24 02:07:03 UTC",
        "build.artifact": "main_component",
        "build.name": "web app",
        "build.version": "1.0.0"
    },
    {
        "build.time": "2019-07-10 15:26:18 UTC",
        "build.artifact": "main_component",
        "build.name": "back-end",
        "build.version": "1.0.1"
    }
]

我很难绕过这种 UTC 格式，所以我只是将其转换为字符串。完成了这项工作，但并不适合所有情况。

// Import moment.js for date validation
var moment = require('moment');

// Load response into object
const jsonData = pm.response.json();

// Test HTTP status code
pm.test("Check if HTTP status code is 200", () => {
pm.response.to.have.status(200);
});

// Check if response contains an array
pm.test("Check if response contains an array", () => {
pm.expect(jsonData).to.be.an("array");
});

// Response array size should always be 2
pm.test("Check if response array size is 2", () => {
pm.expect(Object.keys(pm.response.json()).length).to.eql(2);
});

// In each of the array item, the “build.time” value should be a date time.
pm.test("Check in each of the array item, the “build.time” value is of type datetime", 
() => {
pm.expect(jsonData[0]).to.have.property("build.time");
pm.expect(jsonData[1]).to.have.property("build.time");
});

// In each of the array item, the “build.time” value should be a date time.

// Get full timestamp
var timestamp = jsonData[0]["build.time"];

// Get time
var time = timestamp.substring(0,19);

// Get timezone
var timezone = timestamp.toString().substring(20);

// Test the time format
pm.test("Check in each of the array item, the “build.time” value is of type datetime", 
() => {
pm.expect(moment(new Date(time)).format("YYYY-MM-DD HH:mm:ss") == time);
});

pm.test("Timezone is valid", () => {
pm.expect(timezone).eql("UTC");
});

// In each of the array item, the “build.artifact” value should be equal to 
“main_component”.
pm.test("Check in each of the array item, the “build.artifact” value equals 
“main_component”", () => {
pm.expect(jsonData[0]["build.artifact"]).to.eql("main_component");
pm.expect(jsonData[1]["build.artifact"]).to.eql("main_component");
});

// “build.name” value of the 1st array item must equal to “web app”
pm.test("Check if “build.name” value of the 1st array item equals 'web app'", () => {
pm.expect(jsonData[0]["build.name"]).to.eql("web app");
});

// “build.name” value of the 2nd array item equals to “back-end”.
pm.test("Check if “build.name” value of the 2nd array item equals 'web app'", () => {
pm.expect(jsonData[1]["build.name"]).to.eql("back-end");
});
