Best Automated Browser Testing Tools

Different browsers can behave differently when opening a given page. Sometimes, you might encounter cases where certain browsers cannot open your company page, or it’s behaving strangely when opened from certain browsers.

This can be a major issue in converting viewers to customers, as most users will simply click away from a website that isn’t functioning properly. Due to that, businesses need to put resources into testing their company site to ensure that it’s working properly on different browsers.

Doing this manually isn’t too hard in smaller businesses with only a page or two. However, larger businesses, or simply those with a more expansive online presence, will find that the time required to test out all of your site’s features is excessive. To avoid this, and allow businesses to put man-hours into more worthwhile tasks, most businesses rely on browser testing tools.

Today, we’ll be going over the best-automated browser testing tools on the market.

Here is our list of the best automated browser resting tools:

The tool is incredibly customizable and allows you to write testing scripts in a variety of languages. It also supports Rest APIs to trigger tests and takes screenshots of failed attempts. Despite its breadth of features, Cross Browser Testing is surprisingly easy to use.
  2. Lambda Test An incredibly scalable and powerful tool providing Live interactive testing on real devices and operating systems.
  3. Testim An intuitive, low-code solution that takes advantage of artificial intelligence to take its features to the next level.
  4. TestComplete A comprehensive GUI testing solution that seamlessly integrates into agile environments.
  5. Katalon A low-code, all-in-one testing tool that provides excellent reporting features.
  6. BrowserStack An incredibly powerful, enterprise-focused tool with 15 data centers across the globe.
  7. Eggplant An all-inclusive testing solution with end-to-end testing and troubleshooting assistance.

Why Should I Use A Browser Testing Tool?

Browser testing ensures that your website behaves consistently and can be accessed via a variety of different browsers, devices, and assistive technologies like Google Glass or screen readers. With the abundance of different browsers, devices, and technologies used to access websites, it takes far too long to test each one manually.

Now, if browser testing was a one-and-done thing where testing it out once was enough to ensure future performance it would be feasible, if inefficient, to do it manually. However, browsers all respond to code changes differently, and this is further compounded by differences in devices and operating systems.

The biggest benefits of using an automated browser testing tool are:

  • Lower Infrastructure Setup Costs Automated browser testing makes purchasing each device/OS you’re testing on individually, and helps you eliminate the man-hour cost of setting them up. Since most browser testing tools are cloud-based, you won’t need to pay any infrastructure costs.
  • Broader Coverage Regardless of how much effort you put into manual testing, you’re bound to neglect a set of devices or browsers you simply didn’t think about. Automated browser testing software avoids this completely.
  • Higher Precision Manual testing is always gated behind the attention to detail and attentiveness of the individual performing it. We’re all human, and we all make mistakes from time to time. This could mean forgetting to test a specific browser, or simply not checking a part of the website. Automated browser testing tools run through all of your code and return a 100% accurate record to you.
  • Faster Bug Detection Most browser testing tools will automatically flag bugs within the page’s code.
