Puppeteer has risen to become one of the two most popular and widely used automation frameworks since its original V1 release in January 2018. But there are people out there who still think what it is. So, what exactly is Puppeteer testing? And why do people, developers, and testers in particular, like it so much? Puppeteer was created by Google. It gives a simple but powerful interface in NodeJS for automating testing and other operations using the Chromium browser engine.
Puppeteer is developed so that it can aim to eliminate the trade-off by allowing developers to conduct their tests in the Chromium browser environment and providing them the freedom to employ headless or headful browsers that operate on the same underlying platform as their users.
Puppeteer was also designed with developers in mind. This meant that the developers who maintained popular testing frameworks like Mocha were encouraged to provide Puppeteer support. This contemporary tool was well supported since the very beginning. Therefore, it gained enormous appeal within the development community.
But before we delve into some intricacies, let’s have a look at some fundamentals. Read-on!
What Is Puppeteer?
Puppeteer is a Node.js module, as we said before. It offers a high-level API for controlling headless Chrome or Chromium. Also, it interacts with the DevTools protocol. The tool is supported by the Chrome DevTools team and a fantastic open-source community. As previously mentioned, headless implies you are working with a command line interface rather than a graphical user interface. Puppeteer is designed to run headless, but it may alternatively be set to run full (non-headless) Chrome or Chromium. The program has increased in popularity since its release owing to the large variety of capabilities it provides with extremely lightweight code.
Benefits Of Using Puppeteer
Let’s look at some of the benefits that Puppeteer has to offer:
- Puppeteer is an excellent testing platform since it is simple to use, quick, and offers a diverse set of functions.
- Puppeteer runs quickly because it employs headless Chrome or Chromium. Because headless browsers lack a UI, they are quicker than standard browsers. Furthermore, Puppeteer can run numerous instances of Chrome or Chromium in simultaneously, which speeds up the testing process even further.
- Puppeteer is simple to use. It is built on the DevTools Protocol, which is also used by Chrome Developer Tools. This implies that if you are comfortable with the Chrome Developer Tools, you will be able to rapidly get up and running with Puppeteer. Furthermore, Puppeteer includes a variety of utility functions that make common operations like collecting screenshots and making PDFs simpler.
- Puppeteer offers a plethora of capabilities therefore, it makes it an ideal tool for web scraping as well as automation. Puppeteer, for example, may be used to capture screenshots, traverse websites, make PDFs, and much more. Also, Puppeteer may also be used for testing reasons. Puppeteer, for example, may be used to click on links and buttons, fill out forms, and verify that the intended outcomes are presented on the website.
Puppeteer Automation and APIs
API is basically an abbreviation for Application Programming Interface, and by now you would know it. It is like a piece of software that acts as a conduit between different software systems or online applications. If there’s one thing that we like about APIs, it is their self-esteem. They are also pleasant. Because Puppeteer is an API in and of itself, it offers up a plethora of possibilities for creating a data-gathering funnel that starts with Puppeteer and extends all the way to anywhere you want. You may configure the tool to communicate with another API, displaying the collected data directly in the UI of another web application. Alternatively, you may connect another piece of software (such as your database) and have Puppeteer feed data straight into it.
APIs make data collection and transmission relatively simple. You may use Puppeteer on Chrome to extract eCommerce data and update it immediately on your eCommerce websites. You can scrape SEO data, social networking data, and organization information, and transmit the data straight to where you need it. Whichever one applies to you, the truth remains that the Puppeteer tool allows you to take your data extraction to the next level. Of course, you must remember to scrape ethics and avoid using this tool to breach the privacy of persons or companies on the internet.

- It is critical to utilize the waitFor* functions with caution. Overuse of these functions might cause your tests to run slowly. Parallelizing your testing wherever feasible is critical. This will help your tests perform better overall.
- It is critical to limit the number of activities you execute in each test. This will make your tests run more smoothly.
- Always maintain your test code up to date with the newest Puppeteer modifications. This ensures that your tests are functioning properly.
- When running your tests, use the core team’s supported Node.js versions. This ensures that your tests are functioning properly.
- When running your tests, you must utilize the headless mode. This will make your tests run more smoothly.
- When running your tests, make sure you utilize a properly configured test runner. This ensures that your tests are functioning properly.
- Puppeteer should not be used for site scraping. Many websites’ Terms of Service prohibit this. Use Puppeteer only for lawful reasons.
Make sure you thoroughly study the Puppeteer manual. This will assist you in properly using Puppeteer. It is also recommended that you read the headless-chrome documentation as well. Puppeteer is a robust web page testing and browser automation tool. It is a must-have tool for developers and quality assurance specialists. You may optimize your tests and enhance the overall performance of your testing process by following the best practices outlined above.
The answer to the question “what is Puppeteer?” is quite simple. The issue of the possibilities that exist with this intriguing piece of software, on the other hand, is far larger and more difficult to accurately address. However, we do know that when it comes to online scraping, Puppeteer provides an extra benefit and addresses an issue that many web scraping providers have been suffering with for some time.
