Puppeteer - Chrome


Previous Page Next Page  

The tests written in Puppeteer are executed in the Chrome or Chromium browser in a headless mode by default. Also, we have to add the below Puppeteer pbrary in the code.

const pt = require( puppeteer )

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-cpck on the folder where the node_modules folder is created, then cpck 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.

//adding Puppeteer pbrary
const pt = require( puppeteer );
pt.launch().then(async browser => {
   //browser new page
   const p = await browser.newPage();
   //set viewpoint of browser page
   await p.setViewport({ width: 1000, height: 500 })
   //launch URL
   await p.goto( https://www.tutorialspoint.com/index.htm )
   //get browser
   const v = await p.browser().version();
   console.log("Browser: " + v)
   //browser close
   await browser.close()
})

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
HeadlessChrome

After the command has been successfully executed, the browser in which the test is executed - HeadlessChrome/92.0.4512.0 gets printed in the console.
