Puppeteer - Handling Links/Button

Puppeteer is capable of handling a link/button on a page. Before clicking an element we must be able to uniquely identify it with the help of any of the locators. In Puppeteer, we can click an element only if its dimensions are greater than zero pixel.

In the below image, we shall click on the below highlighted link - Subscribe to Premium Plan having tagname as h1 −

Element H1

To begin, follow Steps 1 to 2 from the Chapter of Basic Test on Puppeteer which are as follows −

Step 1 − Create a new file within the directory where the node_modules folder is created (location where the Puppeteer and Puppeteer core have been installed).

The details on Puppeteer installation is discussed in the Chapter of Puppeteer Installation.

Right-click on the folder where the node_modules folder is created, then click on the New file button.

Node Modules

Step 2 − Enter a filename, say testcase1.js.

Testcase1.JS

Step 3 − Add the below code within the testcase1.js file created.

//Puppeteer library
const pt= require('puppeteer')
async function clickElement(){
   //launch browser in headless mode
   const browser = await pt.launch()
   //browser new page
   const page = await browser.newPage()
   //launch URL
   await page.goto('https://www.tutorialspoint.com/index.htm')
   //identify element then click
   await page.click('h1');
   //get page title after click
   console.log(await page.title())
}
clickElement()

Step 4 − Execute the code with the command given below −

node <filename>

So in our example, we shall run the following command −

node testcase1.js
