Puppeteer - quick start
Puppeteer is a Node library which provides a high-level API to control Chrome.
We have found this tool easy to start and useful in snapshot testing. Today we will show how to do a snapshot testing script.
https://github.com/GoogleChrome/puppeteer you can start to learn Puppeteer from here.
- First install puppeteer on your machine with a line: npm i puppeteer
- Let's create a first script that will open QAProvider homepage and do screenshots with different screen resolutions.
- Let's run the script node qaprovider.js
- Let's check results. We could find that we have a minor bug on 800x600 resolution
View port 640x480
View port 800x600 with a bug
View port 1024x768
This is a quick start with Puppeteer. We will try to do a snapshot tests at the end of this tutorial.
Is it better than Lambdatest ?? I mean we can do snapshot testing using Lambdatest too I guess.
Lambdatest is an online tool and you have to pay to use it.
You can install Puppeteer on your machine, use all the futures for free and have a full control of test automation process.
But Lambdatest has everything configured for you, you just need to click buttons :) It might save a lot of your time if you need all this infrastructure.
