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.

"The reporting is very good, but it could be better."
