Top 7 Puppeteer Alternatives For Your QA Team

Puppeteer is among the top Node.js libraries widely used for headless Chrome testing. It allows testers to do web scraping, taking screenshots, filling out forms, and many more automated testing activities. However, there comes a time when these capabilities are not enough, and testers need to find a Puppeteer alternative.

Puppeteer: The Good, The Bad, and The Alternatives

Puppeteer is actually quite a good library considering the rich array of functions it can perform! Testers chose it for good reasons:

1. You can run browsers in headless mode with Puppeteer. In this mode, all of the actions are performed in the backend without a user interface. Without a visible window, these browsers consume much less resources, bringing faster execution and high scalability. 
2. Puppeteer is designed to work seamlessly with Chrome and Chromium browsers, taking advantage of the Chrome DevTools Protocol.
3. You can easily take screenshots and generate PDFs with Puppeteer, which is really useful for creating visual reports.
4. Puppeteer leverages the asynchronous nature of JavaScript and Node.js so it can handle complex web interactions with ease.
    

However, at the end of the day, Puppeteer is still only a library. When it comes to automation, there are inherent disadvantages to using a library compared to other approaches such as a full-suite automation platform. Here are the top reasons why testers consider a Puppeteer alternative:
 

• Chrome dependency: its advantage can sometimes turn out to be a disadvantage. Having a high level of compatibility with a specific browser environment can come as a cost if you want to move to other environments. 
• High learning curve: as a library, Puppeteer requires testers to have extensive coding knowledge, and most importantly some familiarity with Chrome DevTools Protocol and automation testing concepts.
• Limited scope: the strong areas of Puppeteer ties down to browser testing. If your team wants to expand the testing scope to other AUTs, such as mobile or desktop applications, Puppeteer is usually not the best option. Adopting one more tool to the suite is fine, but then comes the need to unify the testing activities across Puppeteer and the second tool, and that will soon become another challenge for the entire team.

With that in mind, we have listed down the top alternatives for Puppeteer for your team to consider. They are all good tools and frameworks that do exactly what Puppeteer can do, sometimes even compensating for what Puppeteer lacks in its feature suite. Make sure to align your team’s testing needs with what the tool can provide.

Top Puppeteer Alternatives For Your QA Team

1. Katalon

Katalon is a great Puppeteer alternative considering the rich array of features your QA team can immediately receive as you download.
 

You get the best of both worlds with Katalon: either going No-code and leveraging the Record-and Playback features to effortless record your screen and turn it into a test case in minutes or doing it Low-code with the Built-in Keywords where you simply choose the keywords for specific action and only modify the parameters to tell it how to perform that action.

You can totally switch to the Scripting mode to enjoy the full flexibility of editing your script in Groovy.
 

Once you have your test scripts ready, Katalon requires little-to-no setup for execution. Simply choose the environments on which you want it to run and click the Run button. There is also no additional setup needed for parallel execution. You can export your test results to share with the team, or share via Jira and other test management tools to sync results and make informed decisions.

In Katalon, popular test patterns are already implemented, including Object Repositories, BDD, DDT, etc. so you don’t have to redesign them from scratch. Say goodbye to lengthy learning processes and centralize all automation activities in one place.
