Recording limitations and remote access challenges have affected desktop application testing
Katalon Studio has proven effective in our deliverables, particularly in designing the framework where other tools typically require coding in client libraries such as Python or Java. With Katalon Studio, there is no such complexity, allowing us to organize projects modularly based on folder structures without needing to write separate code. The self-healing feature for web application automation and its built-in CI/CD ecosystem integration eliminates the need for external tools for pipeline setup. Katalon Studio excels in CI/CD integration, providing an inbuilt ecosystem without the need for external setup, and it features a postings structure along with keyword and library availability. Newcomers to the team can easily adapt to the setup or project structure, which contributes to its popularity, along with its low-code or no-code capability that allows for a comprehensive platform supporting web, mobile, API, and desktop automation. The self-healing mechanism for test cases autonomously identifies issues with locators and ensures they continue functioning, which is impressive, along with the robust object repository. Katalon Studio has significantly aided our team, especially when clients expect deliveries for CI/CD integration that requires automation test scripts to run on a daily schedule. The self-healing feature automatically identifies available locators for elements in the DOM, ensuring that test cases remain functional. Katalon Studio has positively impacted our organization by facilitating faster delivery when clients have urgent requirements. We can deliver quickly based on urgency due to the features Katalon Studio provides. This has led to significant reductions in time spent on framework configuration, designing, and training individuals who are unfamiliar with the tool, helping us save both time and costs.

"I rate Katalon Studio's scalability a four out of five."

"The most valuable features are test executor and development."
"The most valuable features are test executor and development."
 

Cons

"The tool's maintenance is very difficult since they do not follow call by value or call by reference. Due to this, any change happening is not reflected throughout all the test cases. There are some issues with data parameterization as well."
"While the web testing is great, we expect more from the API testing."
"One area for improvement in Katalon Studio is execution speed. Larger test suites can take more time to execute."
"One aspect that can be improved is testing for desktop applications. I would like to see them support more technologies in this area."
"Restricted choice for scripting language (just Groovy)."
"One needed improvement is that if I run it one time, it works, but if I run it continuously, the application gets stuck."
"Katalon lacks integration with other software, including integrating other languages like .NET and PHP."
"Currently, I'm the only one who can use it because I have a Mac. It is giving a hard time to my team members who are on Linux."
"TestLeft captures a lot of space in terms of memory, which is one issue that can be improved."

Pricing and Cost Advice

"Price-wise, Katalon Studio is a costly product. Considering what the solution provides its users with, I can say that price-wise, Katalon Studio is an okay product."

"It is freeware software, so start using it."

"The pricing is good. It is the market average."
"The cost of Katalon Studio is expensive but it is less than some of the other solutions, such as Micro Focus UFT or SmartBear TestComplete. The cost is the main reason we are using Katalon Studio."
