Hi Paul – glad to hear that Studio works for you well for testing!
Integrating with test tools is simple in principle: Outside the Eclipse ecosystem, you can write a script that updates the XML with the test data (test runs). Inside the Eclipse system, you can programmatically access the data model with EMF.

To me, this sounds like a good solution, considering the constraints of your environment. Within these constraints, I’d be careful to go further, otherwise you’re compromising the low-complexity aspect of your setup.
If you need better support for manual testing, then it may be worth checking for testing tools with native ReqIF support. Using those may simplify integration significantly.
