I mistyped a status method and our offline UR5e display still went green. The fake accepts anything and returns true. Very supportive software, not much of a test. We're waiting for the maintenance setup to become available, so I'd like to use the time to test failed and awkward replies properly.
Developer has made unknown methods fail and linked two saved responses to their SDK version. Next are malformed replies and a good read followed by a failure. We're calling it a reporting test set, not a simulated robot.
