Testing & Validation

Prove an IoT build works before the field does it for you: test methods, environmental and HIL testing, field diagnostics, and the evidence records that make a release defensible.

Your guide: Test Tessa

“A demo proves it can work once; a test proves it keeps working — bring the field, not the bench.”

About This Module

How to Use This Material

• Start with the why: each chapter explains the problem it solves before implementation detail.
• Follow the parts in order when the topic is new, or jump straight to the part that matches your current question.
• Use the interactions and labs as the primary learning tools, not just the prose.
