Testing & Validation

What we test

• Function testing: Each function is verified to produce the expected output under defined input conditions — first on the bench, then on the machine in the field. Functions tried one by one on the bench are re-tested in the field while interacting with each other.
• Communication testing: Recording with an analyser that messages go out in the right cycle with the right content; trialling system behaviour when a bus is cut or a node goes silent.
• Limit and fault-condition tests: A system has to behave correctly not only when everything works, but when things go wrong. What does the software do when battery voltage dips during cranking, when a sensor wire breaks or shorts, when hydraulic oil temperature passes its limit? The expected behaviour is clear: stop the motion, give the operator an understandable warning and log the fault. We create these scenarios deliberately and record the outcome.
• Field testing: Trials, data logging and tuning on the actual machine under working conditions.
• Acceptance testing: Final verification with the customer, working item by item through the function list agreed at the outset.

What is tested gets documented

Every test produces a written output: the test protocol states what was tried and how, the result records state what happened, and the correction records show how each finding was resolved. These documents are both your archive and the basis for future revisions — a year later, the answer to "why does this behave this way" is on file.
