Building a Multi-Mode Valve Test Rig: Software Architecture for Hydraulic and Pneumatic Test Programmes

A general-purpose valve test rig serving multiple valve types needs a test programme abstraction layer that separates the test logic from the specific hardware interfaces. Here's an architecture pattern for that. At the core of the design is a shared test programme interface that every test type must implement. This base interface defines two required behaviours: a method that runs the actual test sequence against the hardware, and a method that interprets the resulting data against specification limits to determine a pass or fail outcome. Keeping these two responsibilities separate, rather th
