Thank you for another hint! Unfortunately, it did not solve the whole situation.
My settings.json looks like this now:
and when I run the whole robot file using the RobotCode: Run Current from the lower part of VSC, it indeed starts only the local suite:
But when I run only a single test case from the suite, using the Play button next to a test case name, it still defines the whole test suite as the entire project folder:
With RobotCode extension disabled and Robot Framework Language Server enabled, using the Play button next to a test case name runs only the one test case as expected:
Is it possible to make RobotCode extension act as the RFLS extension when executing a single test case from a suite?
