Log: Context is Everything (Test Bench Modernization)

Commit: e546b3a

Overview

Modernized the production test bench example to be more "set it and forget it". The biggest win here was adding proper context manager support for UUT handling.

Technical Lowdown

  • UUTHandler: Added __enter__ and __exit__ to UUTHandler. Now it automatically closes serial/VISA sessions even if your test crashes.
  • Logic: Updated the pass/fail logic in the example to use the standardized MeasurementResult objects.
  • Robustness: Improved error catching for serial connections that don't exist on all machines.

Why it matters

Leaving serial ports open in a hung state is the #1 cause of "why is the lab PC frozen?" calls. Proper resource management in the test bench script keeps the hardware happy.
