Smart Factory QC Platform
From paper checklists to automated quality control
The Problem
Paper-Based QC Processes
QC engineers relied on stacks of paper checklists for every equipment test cycle. Handwritten records were prone to errors, difficult to search, and frequently lost or damaged on the factory floor.
No Centralized Result Tracking
Test results were scattered across individual notebooks and local files with no unified system. Tracking pass/fail trends or auditing historical results required manually digging through paper archives.
Manual Equipment Communication
Engineers manually read sensor values and toggled equipment states through vendor-specific tools. Each protocol required separate software, making end-to-end test automation impossible.
Paper checklists filled out by hand for every test cycle
Digital BDD scenarios with structured data capture and searchable history
Manual sensor reading and equipment control via vendor tools
Automated equipment communication via Modbus/MQTT with real-time verification
Approach
BDD-Driven Test Automation
We adopted Behavior-Driven Development (Gherkin syntax) as the foundation for test automation. Domain experts — not developers — define test procedures in plain language using Given/When/Then steps. Each scenario maps directly to real equipment actions through industrial protocols (Modbus TCP, MQTT), executing tests and collecting structured evidence automatically. This approach bridges the gap between domain knowledge and software automation, ensuring test coverage matches actual manufacturing requirements.
BDD Pipeline Flow
Key Features
BDD Scenario Editor & Auto-generation
Write test procedures in plain Gherkin language (Given/When/Then). Non-technical QC engineers can author and review test scenarios without coding. The system auto-generates step definitions that map to equipment control commands, reducing scenario setup time from hours to minutes.
Equipment Communication (Modbus/MQTT)
Unified communication layer connecting to PLCs and controllers via Modbus TCP and MQTT protocols. Read sensor values, write control registers, and subscribe to real-time equipment events through a single abstraction — no vendor-specific tools required.
Real-time Test Execution
Execute BDD scenarios against live equipment with real-time progress tracking. Each step shows live sensor readings, pass/fail verdicts, and captured evidence as the test runs. Engineers can monitor multiple test sessions simultaneously from a single control panel.
Result Dashboard & Reports
Comprehensive dashboard showing test pass rates, trend analysis, and equipment health across production lines. Auto-generates audit-ready PDF reports with full evidence trails including sensor readings, timestamps, and step-by-step test results.
