Extract data

let firstAuthor = res.store.book[0].author; // Nigel Rees
let lastAuthor = res.store.book[res.store.book.length - 1].author; // J. R. R. Tolkien

let firstBook = res.store.book[0];
/*{
  category: 'reference',
  author: 'Nigel Rees',
  title: 'Sayings of the Century',
  price: 8.95
}
*/

let books = res.store.book;
let titleList = [];
books.forEach((element) => {
    if (element.price < 15 && element.category === "fiction") {
        titleList.push(element.title);
    }
});
// [ 'Sword of Honour', 'Moby Dick' ]

let bookList = _.filter(books, (element) => {
    return element.price < 15 && element.category === "fiction";
});
let titles = _.map(bookList, _.property("title"));
//or
let titles = _.map(bookList, "title");
console.log(titles);
// [ 'Sword of Honour', 'Moby Dick' ]

let isbn = [];
books.forEach((element) => {
    if (element.isbn !== undefined) {
        isbn.push(element.isbn);
    }
});
//[ '0-553-21311-3', '0-395-19395-8' ]

Working with time

var moment = require('moment');

now = moment();
 
// 07/05/2021
console.log(now.format("DD/MM/YYYY"));

// tăng 1 ngày và 1 giờ so với thời điểm hiện tại
next_1day_1hour = now.add(1, "d").add(1, "h");
console.log(next_1day_1hour.format("DD/MM/YYYY HH:mm:ss"));

// giảm 1 ngày so với thời điểm hiện tại
yesterday = now.subtract(1, "days");
console.log(yesterday.format("DD/MM/YYYY"));

//milisecond 
console.log(moment().valueOf()); 

//second 
console.log(moment().unix());

Branching

// Call request A
postman.setNextRequest("A");

// Stop
postman.setNextRequest(null);

Assertion

pm.test("name of the test", () => {
   //code to make assertion
});

//skip test
pm.test.skip("name of the test", () => {
   //code to make assertion
});

pm.test("Validate schema", () => {
    pm.response.to.have.jsonSchema(schema);
});
