Inside AutomationView: Leveraging the Python SDK for Automated Regression Testing of SFC Logic

Automated regression testing is common in standard software engineering, but it remains notoriously difficult to implement in the industrial automation world. Engineers often test PLC code manually during the commissioning phase, discovering logic conflicts only when physical hardware is at risk. By leveraging the AutomationView Python SDK, control engineers can run automated regression testing on […]

How to Build Automated Unit Tests for PLC Sequences in AutomationView

In modern software engineering, pushing code to production without running automated unit tests is considered professional malpractice. Yet, in the industrial automation world, engineers routinely download thousands of lines of ladder logic into critical infrastructure relying solely on manual simulation and blind faith. AutomationView changes this paradigm entirely by introducing a native Python-based unit testing […]
