In my application there are 500 test cases which I have categorized based on priority (P1, P2, P3 etc).
I want a configuration in Katalon which ensures that P1 test cases are executed first, P2 cases next and so on.
Please suggest if this type of support is available in Katalon Studio.
You should probably use TestSuites and TestSuiteCollection for this. Just create 3 test suites [P1, P2, and P3 tests suites], add your tests to corresponding test suite, then create a test suite collection, add these 3 test suites into the collection (order them) and make sure you execute them in Sequential Order.
