The Nexus Suite is uniquely architected for a DevOps native world and creates value early in the development pipeline, provides precise contextual controls at every phase, and accelerates DevOps innovation with automation you can trust. Read how in this ebook.

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 one 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 Katalon Studio to other popular automated testing toolsets in the market.

Overview of Tools

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 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.

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.

Tools

Strengths

Limitations

Katalon Studio               

No licensing and maintenance fees requires

Integrating necessary frameworks and features for quick test cases creation and execution.

Built on top of the Selenium framework but eliminating the need for advanced programming skills required for Selenium.

Emerging solution with a small community

Feature set is still evolving.

Lack of choices for scripting languages: only Java/Groovy is supported.

Selenium

Open source, no licensing and maintenance fees

Large and active development and user community to keep pace with software technologies.

Open for integration with other tools and frameworks to enhance its capability

Testing teams need to have good programming skills and experience to setup and integrate Selenium with other tools and frameworks.

New teams need to invest time upfront for setup and integration

Slow support from the community.

UFT

Mature, comprehensive automated testing features integrated into a single system.

Dedicated user support plus an established large user community.

Requiring only basic programming skills to get started with test creation and execution.

Costly solution: license and maintenance fees are considerably high.

Possible high costs for upgrades and additional modules.

Supporting only VBScript.

TestComplete

Mature, comprehensive automated testing features integrated into a single system.

Many scripting languages to choose from.

Only basic programming skills needed.

Like UFT, considerable licensing and maintenance fees needed for TestComplete.


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, like Katalon, offer a viable alternative to both commercial and open-source automated testing solutions.
