Excellent response, Luc! Big Grin | :-D

It reminds me a bit of my former career designing automated test systems for missiles. The #1 rule of Testability: A Testable product is both Observable and Controllable. All electronic control systems use feedback; an open-loop system is inherently undesirable, as functional accuracy is limited to component accuracy without active feedback. But if a tester cannot see interior points in the circuit, and can't open the feedback loop to measure values inside, it is not possible to test the circuit. There also must be a means to force a change of state in the circuit and observe the results in order to make an effective test.

The same principle applies to software; if you can't observe the internal states, you can't expect to diagnose a problem when it occurs. Logging - not only errors, but the system states before and after a fault - makes diagnosing the cause of a problem far easier. In many cases, it probably is the only way to diagnose a failure.
