FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Test Types & Methods
What Is HALT and HASS Testing
HALT finds design limits by stressing to destruction, HASS screens production units. How both work, when to use each, and how to record results.
- Test Data & Analytics
Export Test Data to Power BI
Learn how to export test data from TofuPilot to Power BI using CSV exports and the REST API for custom management reports and cross-system analysis.
- Test Data & Analytics
Anomaly Detection in Hardware Test Data
Learn how to detect anomalies in hardware test measurements using TofuPilot's analytics and automated limit checking.
- Compliance & Traceability
What Is First Article Inspection (FAI)
First article inspection (FAI) verifies the first production unit meets all specifications. Learn how FAI works and how to track it with TofuPilot.
- Test Station Setup
How to Build a Test Operator UI in Python
Build a production-ready operator interface for hardware tests using Python, OpenHTF, and TofuPilot. No frontend code required.
- Compliance & Traceability
Track Firmware Versions in Production
Record firmware versions as metadata in OpenHTF tests so TofuPilot lets you filter runs, trace failures, and prove compliance by software build.
- Getting Started
Structure a Production Test Script
Structure a Python test script for production: separate limits from logic, instruments from steps, and make the layout survive a year of changes.
- Test Station Setup
How to Set Up Kiosk Mode for Test Stations
Kiosk mode locks a test station to the operator UI. Learn how to configure Chrome kiosk mode, auto-start, and barcode scanner integration.
- Migrating from Legacy Systems
Migrate from LabVIEW TestExec to Python
A practical migration guide from LabVIEW TestExec to Python-based test automation with OpenHTF and TofuPilot, covering architecture mapping and code examples.
- Test Station Setup
Version Control Hardware Tests with Git
Learn how to version control hardware test scripts with Git and link test results to code versions in TofuPilot.
- Test Data & Analytics
How to Improve First Pass Yield
Actionable strategies to improve first pass yield (FPY) in electronics manufacturing, with root cause analysis, Pareto charts, limit refinement, and TofuPilot.
- Migrating from Legacy Systems
OpenHTF vs pytest for Hardware Testing
Compare OpenHTF and pytest for hardware test, and see where the TofuPilot Framework fits, with real code and guidance on when to use each.
