I have test suite collection with 7 test suites and 2 mobile devices to run the test. I would like to run on parallel. If I provide 2 concurrent sessions sometimes app got closed for test suites and entire test suite got failed.
Suggest me right way to define parallel configuration.
I think you should try delay between instances about 120 seconds. And you are setting 1 max concurrent instances, it means the maximum number of test suites executing at the same time to be just 1. Try with 2 or 3 or any bigger. (Test Suite Collection | Katalon Docs)
If you still cannot run with this setup, try run with command line: automated tests - Katalon- Parallel execution of multiple browsers through cmd - Stack Overflow
