Ramanagowda Hullur - PeerSpot reviewer
Senior Automation Engineer at Stryker
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.

Automated API and database regression testing has reduced resources and improved insurance validation
I have noticed some errors regarding the connection with Bitbucket or Git. It generally takes some time in SmartBear and ReadyAPI. From the testing perspective, it saves a lot of time because it covered a whole regression suite with database and data-driven testing. It generally saves us time from fetching the values manually from UI. Instead, you can run your regression suite on a daily or weekly basis. This helps us to identify some errors as well as saves us time. There is a delay in connection with SmartBear API Hub; sometimes the connection is lost between the Bitbucket and ReadyAPI. When we try to reconnect those from the properties level, from the setting level, it generally takes a lot of time. This perspective can be improved with the Bitbucket and Git connection. We can also integrate a particular framework in ReadyAPI itself so that we can also run our Selenium code from the UI automation perspective. Right now, we are currently using that feature, but it requires framework-level changes. We can provide it to every user so that users can easily run their Selenium scripts, fetch the APIs, and validate the database. This helps us to create one-to-one end-to-end flow for the purpose of testing. We can enhance that feature and we can also enhance the Git functionality because we are using Sourcetree as well for connecting Bitbucket and ReadyAPI in order to push and pull our changes. That particular functionality takes a lot of time. Sometimes the changes that we have made in our regression suite are not reflecting on the recent changes in ReadyAPI. This is sometimes difficult to track and takes a lot of time to refresh that. I would say we should enhance the UI automation feature and we can also enhance the Git connection feature as well.
