A bit like @anon46315158 is telling you, you need to decide what your Test Case philosophy is:

Choose:

1. Test Cases should be standalone. Each TC does exactly what it needs to do to execute the user scenario and then quit.

2. Test Cases are always part of a Test Suite. Each TC can benefit from and rely on TCs that executed earlier in the suite.

Choose #1 or #2. Trying to do both, while not impossible, will likely cause confusion – _especially if other people are using your code base_ – and even moreso if you’re new to testing.

Aside: you could consider using `WebUI.callTestCase()` which, sadly, is [no longer documented](http://forum.katalon.com/t/webui-calltestcase-api-is-not-documented/67452) for some reason. But again, you’ll need to make sure dependent TCs are suitably documented as reliant on a parent/host TC.
