Puppeteer flexes its muscle where selenium misses out. It is not just limited to interactions with the web application under test performing tasks like for e.g. interacting with dom, submitting forms, generating screenshots and pdf of web pages but also in intercepting network activity, throttling CPU and network, generating timeline trace and mocking API amongst some. The puppeteer can be easily be used to write end-to-end automation test suites with the benefit of getting a detailed timeline of the performance of all the assets (images, javascript files and so on).

1. Puppeteer : Is it time to ditch
Selenium?
Mindfire is a software service provider offering
customized technological and digital solutions through
offshore software development using Agile methods.

2. Google has introduced a new library based on
Chromium’s dev tool protocol. The library grants high-
level API to interact with chromium and handle most
tasks which you can perform using Chromium dev tools.
The library is implemented in node.js and is really easy
to get started once you install required packages using
the node package manager.

3. Why Puppeteer?
Puppeteer flexes its muscle where selenium misses out. It is not just limited to
interactions with the web application under test performing tasks like for e.g.
interacting with dom, submitting forms, generating screenshots and pdf of
web pages but also in intercepting network activity, throttling CPU and
network, generating timeline trace and mocking API amongst some. The
puppeteer can be easily be used to write end-to-end automation test suites
with the benefit of getting a detailed timeline of the performance of all the
assets (images, javascript files and so on).
Engineers can easily switch between headless and non-headless modes. While
writing the automation suite, non-headless mode gives a good view of how the
browser is interacting with the application under test and helps in debugging;
just like in Selenium. But in production, we can execute suite in a headless
mode as it reduces execution time and save resources.
