What Is Playwright?
Playwright Automation Testing
Playwright is open source under the Apache 2.0 license, and has over 40k stars on GitHub, making it one of the most popular test frameworks around.
Advantages of the Tool
Playwright developers frequently release new features making this tool even easier to use. A few of the many advantages are listed below:
- The installation of this test automation framework does not take much time for configuration.
- In relation to the selected coding language used by the tester, the installation steps may vary.
- Playwright supports multiple coding languages such as Java, Python, and so on. Playwright also supports testing on various browsers e.g. Chromium, Webkit, Firefox and Safari
- Whether it is multi-tab or multi-window, Playwright can handle any test scenario. If a test scenario requires the tester to shift between tabs or windows, this automation tool helps them to do this.
- This tool is developer-friendly, providing a lot of debugging options.
Importance of Playwright
- Playwright is one of the few test automations tools that can be used on multiple devices; this helps testers look for scenarios on the desktop as well as mobile platforms.
- This tool is capable of covering various scenarios, while offering support for file downloads, uploads, and native input events.

To Sum Up
What Is Puppeteer?
Puppeteer was originally created by the Chrome/Google development team, Puppeteer automates Chromium based browser (Chrome, Edge, Brave and even Firefox). It runs in both headless and interactive mode. Headless being the default, it runs the browser emulation without needing to render it to screen.
With a massive 79.8k stars at the time of writing, this is one of the most popular libraries on Github, and is used by many organisations for many purposes ranging from test, to gathering information for several purposes. Adappt used this in 2020 to gather Covid stats from each govt for the World Health Organization.
The real power of Puppeteer is that it will faithfully render pages in the same way as Chrome / Edge, using the very latest release of the Chromium engine and all whilst running in headless mode. This makes it perfect for integration into CI/CD pipelines running on servers without GPUs
Puppeteer can be used for automated browser testing. It is fast and robust and has a ‘clean syntax’ that allows the user to write readable tests.
What Is Selenium?
Selenium is now one of the most popular free (open source) automation tools and automates the browser to perform the many actions that would have previously been done manually. As mentioned, it records; has playback, and highlights errors while testing web apps. It can run multiple scripts across several browsers.
It supports various operating systems and works across various browsers (e.g. Firefox, Chrome, IE, Edge, Safari, Opera) and devices.
It is easy to install and provides constant updates. It has multiple simple and easy navigation tools to assist writing test cases without requiring scripts.
What Is Watir?
WATIR is an acronym for Web Application Testing In Ruby and is pronounced the same as the word ‘water’, it is a simple and flexible tool. It is an open-source family of Ruby libraries for automating web browser testing, and the Watir WebDriver (the modern version of the Selenium based Watir API), it drives/supports Internet Explorer, Firefox, Chrome, Opera and Safari browsers. It is a simple and flexible tool and facilitates the writing of automated tests which are easy to both read and maintain.
It interacts with a browser the same way a person or a manual tester would do, in effect it mimics a real person, it logs in, clicks on links, fills in forms, validates text and so on.
It also runs in headless mode (HTMLUnit).
