Resolve "Improve eufs test command"

Merge Request Description

Summary

Not sure what people think of this, I wanted to run something like

eufs test msg_buffer -c --regex pose_buffer

to see if a quick fix for a test works. I've been doing the lengthier colcon test so I think this will be useful

Reproducible Test Plan
