FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Concepts & Methodology
What Is Generative Test Design
Generative test design uses AI to create test plans, scripts, and measurement strategies from product specifications. Learn where it works today and where.
- Getting Started
Handle Test Failures and Retries
Learn how to control OpenHTF phase failure behavior, implement retry logic, and ensure clean teardown in production tests with TofuPilot.
- Test Types & Methods
What Is Ongoing Reliability Testing (ORT)
Ongoing reliability testing pulls units from the line and stress-tests them on a schedule. How ORT works and how to track results over time.
- Test Types & Methods
Track Battery Cycling Test Data
Learn how to log charge/discharge cycling data, track capacity fade, and monitor cell performance across production using TofuPilot.
- Migrating from Legacy Systems
TestStand Alternatives for Manufacturing Test
NI TestStand alternatives for manufacturing test: what replaces sequences, process models and step types, and what a migration actually involves.
- Migrating from Legacy Systems
Where to Store Production Test Results
Test results scattered across spreadsheets and shared folders stop working at a predictable point. Here is when to move, and what to move to.
- Migrating from Legacy Systems
OpenHTF vs NI TestStand for Manufacturing Test
Compare OpenHTF and NI TestStand for manufacturing test automation, with feature matrices, code examples, cost analysis, and database integration differences.
- Scaling & Monitoring
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
Set up HIL testing for embedded systems with Python, using the TofuPilot Framework or OpenHTF, covering GPIO, ADC, PWM and CI integration.
- 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
Use pytest for hardware testing: where fixtures fit, what pytest does not give you, and how to get structured results into a dashboard.
- 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.
