Production Test Validation at Scale
Learn how to validate your production test process at scale using TofuPilot's statistical analysis, Cpk tracking, and yield monitoring.
- Test Types & Methods
HIL Testing with Python
Learn how to set up HIL testing for embedded systems with Python, OpenHTF, and TofuPilot, including GPIO, ADC, PWM, and communication interface testing.
- Compliance & Traceability
Test Traceability for Medical Devices
Map FDA 21 CFR Part 820 and ISO 13485 requirements to TofuPilot features for device history records, test documentation, and audit trails.
- Getting Started
Use pytest for Hardware Testing
Learn how to use pytest to automate hardware tests and upload results to TofuPilot for centralized tracking and analytics.
- Test Types & Methods
Battery Cell Grading and Binning
Learn how to grade and bin battery cells based on test data using TofuPilot for capacity matching, impedance sorting, and production traceability.
- Test Types & Methods
What Is HALT and HASS Testing
HALT finds design limits, HASS screens production units. Learn how both work, when to use each, and how to track results with TofuPilot.
- 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
Learn how to organize an OpenHTF test script for production use, including phase ordering, plug management, configuration, and multi-SKU support with TofuPilot.
