• performing a test procedure for testing the device under test on the basis of test procedure data, upon receipt of the test procedure activation signal, wherein the test procedure is adjustable upon receipt of a feedback signal from the device under test;
• and
• adjusting the test procedure by,
• receiving a feedback signal from the device under test;
• determining from the feedback signal properties of a physical connection between the test device and the device under test;
