I've been using Katalon Studio for two years.
My main use case for Katalon Studio is working on automation. I created and executed test scripts, used data-driven testing, and integrated runs with Jenkins for continuous testing. I use Katalon Studio reports to track and fix the failures. For example, in one of my projects, we automated the user login and product purchase flow using Katalon Studio. The goal was to ensure that the login, product search, add to cart, and checkout functionalities worked correctly after every deployment. I created reusable test cases for login, navigation, and payment, used test data from Excel for multiple user credentials, and set up the suite to run automatically through Jenkins integration. The automation reduced the manual regression effort and helped identify the broken flows early in the QA cycle.
The reason I chose data-driven testing and Jenkins integration for my project is that Jenkins helps schedule and run automated test suites whenever a new build is deployed. This ensures early detection of issues and consistent quality without manual intervention. It provides reports and integrates easily with tools such as Katalon Studio, Git, and Jira. I focused on data-driven testing, which allows running the same test cases with multiple sets of input data, such as different usernames, passwords, and payment methods. This increases test coverage, reduces duplication, and ensures that the application handles various data conditions correctly.
I wanted to do something automated for the things we list for sanity testing. Whenever a new build is deployed, a sanity check should be done. If the automated tests are already written, it makes it easier. The login and checkout flow in Katalon Studio using data-driven testing and Jenkins helps reduce manual regression time, ensuring faster feedback after every build. If any issue arises, we can inform the developers at the earliest.
