A defining factor for successfully applying test automation in software projects is choosing and using the right set of test automation tools. This is a daunting task, especially for those new to software test automation because there are so many tools in the market to choose from, each having different strengths and weaknesses. There is no tool that can fit all automated testing needs which makes finding the right tool difficult. Learn how to identify the right automation tool for your project with this qualitative comparison of popular automated testing toolsets in the market.

Overview of Test Automation Tools

Selenium is the most popular automation framework that consists of many tools and plugins for Web application testing. Selenium is known for its powerful capability to support performance testing of Web applications. Selenium is the most popular choice in the open-source test automation space, partly due to its large and active development and user community.

HP Unified Functional Testing (UFT), formerly QuickTest Professional (QTP), is probably the most popular commercial tool for functional test automation. HP UFT offers a comprehensive set of features that can cover most functional automated testing needs on the desktop, mobile and Web platforms.

TestComplete is also a commercial integrated platform for desktop, mobile and Web application testing. Like UFT, TestComplete offers a number of key test automation features such as keyword-driven and data-driven testing, cross-browser testing, API testing and CI integrations. This tool supports a number of languages including JavaScript, Python, VBScript, JScript, DelphiScript, C++Script, and C#Script for writing test scripts.

Katalon Studio is an automated testing platform that offers a comprehensive set of features to implement full automated testing solutions for mobile and Web applications. Built on top of the open-source Selenium and Appium frameworks, Katalon Studio allows teams to get started with test automation quickly by reducing the effort and expertise required for learning and integrating these frameworks for automated testing needs.

Test Automation Tools Comparison

The table below provides a comparison of the tools based on the key features of software automation.

Strengths and Weaknesses

Below is a summary of key strengths and limitations of the tools, based on the comparison testing tools strengths weaknesses compared

There is no one-size-fits-all tool for automated testing. It is highly recommended that testers evaluate various tools in order to select what would best meet their automated testing needs. Programming languages and technologies used to develop software continue to evolve, as do the automated testing tools, making cost a significant factor in tool selection. Commercial vendors often charge for tool upgrades, which can be substantial if your software uses emerging and frequently changing technologies. Open source and non-commercial tools, on the other hand, do not incur additional charges but require effort and expertise for integrating new upgrades. It is difficult to find the support and expertise needed for integrating various tools and frameworks into open-source solutions. Emerging tools that integrate with open-source frameworks offer a viable alternative to both commercial and open-source automated testing solutions.

    i have never heard of Katalon Studio sounds very useful, i love that it uses selenium and appium. will be researching more about it, thanks for sharing!

    Hi Rai, thanks for sharing this helpful post. Among the tools above, I currently use Katalon Studio for my test. I found it a bit hard to approach automation by Selenium as I have less required skills and knowledge. I definitely love the tool, especially the latest 4.5 version. It totally amazed me. I think it’s not only suitable for freshers but also experienced testers since fresh ones can use recording and keywords to build automation tests and the expert have a full IDE to build advanced scripts.

    However, I suggest if your ability is good enough, learning Selenium is not a bad ideas. It’s help you expand your knowledge in automation.

    Thanks for sharing! I’m currently learning about automation testing so this article is highly valuable to me.

    Thank Rai for your post. Among the mentioned tools, I experienced Selenium and recently Katalon Studio. They are all astonishing! However, those who unfamiliar with test automation will find Katalon as an easier approach since it hides technical complexities behind and provides users powerful & friendly UI with the manual mode. I strongly recommended Katalon Studio for freshers/ low budget testing teams as it’s freely available, quite powerful and developed by a passionate team.

    For those who prefer Selenium since it a most common open-source tool, there is no problem as well, but notice, it will be a bit harder to approach. Open source frameworks, in general, require high technical skills and knowledge when using, so it may more suitable for experienced testers.

  6. Admiring the time and effort you put into your website and detailed information you present.
    It’s nice to come across a blog every once in a while that isn’t the same out of date rehashed material.

    Excellent read! I’ve saved your site and I’m adding your RSS

    If you are busy with visual regression testing, you should definitely check out Screenster ( ). This QA automation tool is capable of easy CSS testing of various types of web UI including complex AJAX-based applications. It also has the following advantages:

    Visual baseline: screenshots are captured for each user step during test recording

    Screenshot based comparison: Screenster compares images captured during a playback to those from the baseline and highlights all differences

    Smart CSS selectors: tester can select CSS elements on the screenshots and perform actions with them – e.g. mark them as ignore regions to exclude from further comparison

    Advanced test maintenance options: it is possible to add or delete steps, modify actions on each step, override tests with new parameters and so on.

    Are you interested to try it? Screenster can be downloaded after a free registration.

    Thank Rai for posting, it’s good to meet this article right at this time. It presents a very informative and visual comparison. I wondered which tool should I use to start which automation and now I think kind of Selenium based products may should my case the most. Will try to check out Katalon soon!

    Gartner has stated that by the end of 2017, 75% of the companies will have more than 4 tech developments or software products for automation, which will be implemented as part of their IT management strategies. And, as QA is an important part of the whole development methodology, the integration of automated testing tools aims to accelerate the QA assessment and analysis. Automated testing tools are both cost- and time-efficient. They reduce the chances of human errors as well. In fact, a very good article on ‘’how automation tools boost your IT business and development’’ that I would like to share with you, is this one: . I hope you’ll enjoy reading it, as I did.
