How to Select Automation Testing Tools

I don’t think there is one tool that all teams should use as their software testing technique. What you decide to choose should be based on your team’s unique needs.

I always recommend, regardless of what automation testing process or tools are selected, to do these:

  1. A two-week proof of concept (POC)
  2. Make sure the solution actually fits in with your team's development workflow.

In the recent podcast with Tobias Müller on “Next Generation Functional Visual Test Automation,” I had the opportunity to delve into the workings of

This platform, as discussed, pioneers the application of AI in the realm of autonomous software testing, presenting a viable solution for some of the most common challenges faced in test automation. potentially speeds up your testing process threefold. Its primary allure comes from its reliability, emphasizing eliminating the unpredictable elements – or “flakiness” – often associated with automation testing.

Plus, it significantly lessens the maintenance effort, which could alleviate the stress involved in ensuring the continuous operation of your testing.

One significant aspect differentiating from its counterparts is removing the need for XPath, IDs, and other selectors. This implies reducing the technical complexities typically associated with the automation process, making it more approachable and efficient.

The platform is designed with a user-centric philosophy, enabling the automation of entire user journeys. This means you can perform tests across applications, browsers, devices, and platforms, irrespective of their specific technologies. If a user can interact with a system, can automate testing. includes a low-code and no-code designer in its platform, alongside a management cockpit providing visual and detailed reporting. The aim is to offer a comprehensive test lab that is accessible and informative for users of varying expertise levels.

Finally, one of the critical features of is its ability to integrate with your CI/CD pipeline smoothly while offering a team workflow. This seamless integration could be beneficial in achieving efficient, continuous testing and delivery in software development.

1. Selenium WebDriver

Selenium Automation Logo | TestGuild

OK–this is a no-brainer. Selenium is now the leading open-source automated regression testing option for browser-based website automation.

But, Selenium is not a standalone testing tool.


  • It’s an API that allows you to programmatically write tests using most programming languages to interact with a browser as a real user would.
  • This is probably one of the most popular website automation testing tools listed. In fact, you can't start a list of automation tools without having Selenium first.
  • It is also the quality software that started the Agile and DevOps automation revolution and is in most demand in SDET job descriptions.

2. Cucumber

Cucumber BDD Automation | TestGuild

Cucumber was not designed to be an automation test tool; it’s a tool that helps convert and removes ambiguity from requirements before your team invests time in writing code.


  • Once you’ve created test scenarios, you can generate what they can “executable specifications,” using whatever automation library is supported by the programming language you use.
  • Although Cucumber’s main benefit is helping communication and collaboration, many teams use it simply as an automated testing tools framework.

If you decide to use Cucumber, I highly recommend reading The Cucumber Book: Behavior-Driven Development for Testers and Developers.

3. Serenity

Serenity Automation Tool | TestGuild

If you need an automated test tool Java-based framework that integrates with behavior-driven development (BDD) tools such as Cucumber and JBehave, and lets you keep your test creation at a high level while accommodating lower-level implementation details in your reports, Serenity BDD (formerly Thucydides) might be the tool for you. It's designed to make writing automated acceptance and regression tests easier.


  • Serenity acts as a wrapper on top of Selenium WebDriver and BDD tools. It makes writing BDD and Selenium tests easier because it abstracts away much of the boilerplate code you sometimes need to write to get started.
  • Serenity also offers plenty of built-in functionality. This includes such as handling WebDriver management, managing state between steps, taking screenshots, running tests in parallel, facilitating Jira integration, and more—all without having to write a single line of code.
  • Serenity creates highly detailed reports. Out of the box, it creates living documentation you can use not only to view your Selenium BDD test results but also as documentation for your application.
  • It also has an extra annotation method called @Step. When used correctly, @Step gives you an extra level of abstraction that makes your tests more reusable and maintainable.
  • Serenity takes care of many things you would typically have to code from scratch if you were creating your own BDD framework. It’s one of the better open-source frameworks available, although I might be a bit biased; it’s the tool I use for my day-to-day test automation efforts.

John Ferguson Smart also wrote an excellent book on BDD in Action that includes tips and tricks for using Serenity and other automated testing process tools.


4. Unified Functional Testing – Quick Test Professional

UFT Automation Tool | TestGuild

Unified Functional Testing (UFT) is a commercial test automation tool initially developed by Mercury Interactive and named Quick Test Professional (QTP). It was later acquired by HP and rebranded as Unified Functional Testing. Micro Focus recently purchased it, so Lord knows what the marketing geniuses there will call it.

Before Selenium became the de facto browser-based automation solution, QTP/UFT was one of the market's most popular automation testing tools.


  • It’s still one of the top automation tools for folks who need a tool that automates more than just web browsers.
  • It has automated web testing functionality and support for other diverse technologies like WPF, NET, Oracle, PeopleSoft, SAP, Siebel, Terminal Emulators, and more.
  • Using a tool like UFT allows you to automate complete end-to-end testing workflows that might interact with non-web-based applications.

10. Applitools

Applitools Visual Automation Tool | TestGuild

While most automated software testing tools on this list were created for functional testing, Applitools was developed from the ground up, specifically for visual validation assurance. Visual Software Testing is the process of validating the visual aspects of an application’s User Interface (UI).

In addition to validating that the UI displays the correct content or test data, Visual Testing focuses on proving the layout and appearance of each visual element of the UI and the UI as a whole.


11. Watir

Watir Automation Testing Tool | TestGuild

Watir is an open-source Ruby library for automating tests.

Watir interacts with a browser the same way people do:

Appium is a free, open-source, cross-platform UI mobile testing tool. It allows you to write UI tests for your mobile apps, Android and iOS, and other OSs. It also lets you create test scripts using the Selenium JSON writer you know and love from web automation assurance.

Appium is becoming an industry standard for mobile testing, much as Selenium WebDriver became the standard for browser-based automation a few years ago.


15. Robot Framework

robot framework | TestGuild

You can't go wrong with the Robot Framework if you want to use Python for test automation.


  • This mature product, created for testers, uses a keyword-driven approach to make tests readable and easy to create.
  • It also includes many test libraries and other tools you can use.
  • The Robot Framework is Python-based, but you can also use Jython (Java) or IronPython (.NET).
  • While the Selenium WebDriver library may be the most used external test library, Robot Framework can test things other than websites, including FTP, MongoDB, Android, and Appium.
  • In addition to all this open-source awesomeness, it has a lot of APIs that help make it as extensible as possible.
  • The keyword approach used by Robot Framework is excellent for testers who are already familiar with other vendor-based, keyword-driven test tools, making the transition to open source much more comfortable for them.

If your team is mostly made up of testers, Robot Framework is an excellent option for your automation framework.


16. Broadcom Agile Designer

Broadcom Software

The Broadcom Agile Requirements Designer automation tool takes a unique approach to software test automation. Rather than focusing on the code, it creates automated tests automatically using model-based requirements.

20. TestPlant

TestPlant EggPlant | TestGuild

TestPlant is one of the only test automation tools on this list that has strong support for Apple’s platform. Because of its unique, image-based recognition abilities, it's known for its ability to test hard-to-automate applications, especially those with object recognition issues.

Unfortunately, however, anyone who has done image-based, functional test automation understands how difficult these types of tests can be to maintain. Some customers have noted that as an issue.

21. TestArchitect

Test Architect | TestGuild

21. TestArchitect

TestArchitect is a codeless, keyword-driven automation framework that makes it easy for teams to create and manage large test suites.

When I asked Hung Q. Nguyen, the co-founder of LogiGear, why he created Test Architect, he mentioned that creating a test is one thing. But tests change, and they change very rapidly.

How do you rapidly change the test, maintain, and update it so that you can scale? That was the thinking behind the design of the Test Architect.


22. Galen Framework

Galen Automation Framework | TestGuild

If you need to focus your own automation software testing efforts on user experience design (UX) or layout testing, you can use this tool.


  • Created specifically for UX testing acceptance testing, Galen has a special syntax and rules you can use to describe and verify your application’s layout.
  • It also lets you specify your browser size and then run tests against your software to check layout specifications.
  • Galen tests also generate detailed HTML reports with screenshots, including a visual image comparison with a cool heat map feature.
  • You can write tests in a simple text file using the Galen syntax, JavaScript, or Java.

Testim leverages machine learning to speed up the authoring, execution of test coverage, and, most importantly–maintenance of automated tests. Their goal is to help you to start trusting your tests.

Testim focuses on reducing your flaky tests and test maintenance, which they see as one of the most significant challenges for most organizations. Oren Rubin, the co-founder of Testim, mentioned in a recent TestTalks interview that the firm’s primary goal is to help liberate test automation from the exclusive realm of developers and make it simple enough for anyone on the team to create.



Cypress Automation Testing Framework | TestGuild

Compared to most of the other tools on this list, Cypress is a more developer-centric test automation framework that focuses on making test-driven development (TDD) a reality for developers.


  • One of its design principles was to be able to package and bundle everything together to make the entire end-to-end testing experience pleasant and simple.
  • It has a different architecture than Selenium; while Selenium WebDriver runs remotely outside the browser, Cypress runs inside of it. This approach delivers more consistent results since it can understand everything that happens inside and outside the browser.
  • It also gives you native access to every object without requiring you to deal with object serialization or over-the-wire protocols. You’re pulling your application into Cypress. As a result, it can synchronously notify you of every single thing that happens inside the browser so that you have native access to every distributed object model (DOM) element.
  • Cypress also makes it easy to drop a debugger into your application, which in turn makes it easier to use the developer tools while you’re developing.

Of all the automation testing tools listed here, Cypress is the one that I hear most developers prefer to use.


27. WebDriver.IO | TestGuild

WebDriver.IO is another cross-browser testing automation testing tools module. Still, this one is for Node.JS, which makes it possible to write super easy Selenium tests in your favorite BDD/TDD test framework that will either run locally or in the Cloud using Sauce Labs, BrowserStack, or TestingBot.

I like how Kevin Lamping in TestTalks Episode 179 describes the chief benefit of using WebDriverIO as being like the SeleniumJS binding on steroids!

WebDriverIO is agnostic about the test framework you use so that you can leverage tools like Cucumber, Jasmine, and Mocha+Chai. If you’re a QA engineer who’s just getting started, WebDriver.IO might be the way to go because–in my opinion–JavaScript with WebDriverIO is a lot easier to pick up than Java.


28. Mabl

mabl | TestGuild

Mabl is one of the newer automation testing tools on the market that focuses on the hot trend of using AI and machine learning to help folks with their testing efforts.

In a nutshell, to get started, you merely point Mabl to your application.

  • It will then crawl your app’s screens and begin to run default tests that are common for most applications.
  • Along the way, it also uses machine learning algorithms to improve test execution and defect detection.
  • Using the Mabl trainer chrome extension, you can also train Mabl to learning journeys in your application which describe the functionality Mabl will test.


29. Jest

Jest Automation With Javascript | TestGuild

There are tons of JavaScript test automation frameworks out there that you might choose from, but Jest seems to be the most developer-friendly

Progress Telerik Automation Logo | TestGuild

For those of you who may not be familiar with Test Studio, it is a visual .NET-based end-to-end automation tool backed by Progress Telerik, which is the home of the favorite free debugging tool Fiddler.

Test Studio supports functional UI, load/performance, and RESTful API testing and is a good fit for both the less experienced QAs as well as savvier software engineers in the test.

I also know a few automation test engineers who use Progress’s Test Studio as a front end for their Selenium test automation efforts. Strengths of Progress' Test Studio is its hybrid technology to locate elements based on a combination of object ID and image (making the tests a lot more stable) as well as integration with Visual Studio and its supported languages.

32. Sahi
