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.

Our primary use case is Point of Sale (POS) testing The most valuable features are test executor and development. TestLeft captures a lot of space in terms of memory, which is one issue that can be improved. We have been using SmartBear TestLeft for the past month. Stability-wise, TestLeft is…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"This solution is very user-friendly to learn and implement, and less technical knowledge is required to handle automation."
"We are now performing automated testing in 15 minutes, which were previously taking a long time when doing it manually."
"Katalon Studio has positively impacted my organization because I have noticed that I can save more than 50% of our time automating test cases."
"The solution has very good integration capabilities overall."
"The best thing about the solution is that there is a record and playback functionality."
"I personally like the 'Object Spy' feature of this tool. It makes it easy to find an element on the web page."
"It is a good tool and provides all the essential features for our business requirements."
"The most valuable feature is the capability of doing end-to-end testing for both web and mobile apps."
"The most valuable features are test executor and development."
 

Cons

"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. My team members are using Linux, and Katalon doesn't support Linux very well. It keeps on crashing. It crashes and shuts down almost every time they save their work, so they are not able to use it. It should have good support for Linux. We don't know what the problem is. If the Katalon team can pick up this issue, it will be very helpful."
"Its stability needs improvement."
"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."
"Stability is one of the main issues with the system crashing if there's a new release that hasn't been sufficiently tested."
"We have had some issues when it comes to stability, which is something that needs to be improved."
"One area for improvement in Katalon Studio is execution speed. Larger test suites can take more time to execute."
"The free version of the solution is not user friendly at all."
"Katalon Studio could improve having visual testing, but I think they're launching that feature very soon. We would like to see an increase in the usage of AI."
"TestLeft captures a lot of space in terms of memory, which is one issue that can be improved."
