What unusual test did engineers conduct while the Starliner was still attached to the ISS?

Answer

Hot-fire tests of some problematic thrusters

NASA authorized flight controllers to deliberately fire some of the malfunctioning thrusters while the spacecraft was docked. This allowed teams to stress the system, gather new data, and validate potential workarounds safely.
