🧪 TDPD - Test Driven Product Development

We're familiar with TDD (test-driven development) in the software world. Basically the idea is to create unit tests before implementing a feature.

What if we extend this to systems, hardware, and even mechanical?

• Write end-to-end system tests before developing a feature.
• Design/build test fixtures before designing the PCB. PCBs are cheap and fast to build now - so build an additional one for testing.
• Create automated checks on 3D CAD models for fit/clearance, etc. Does the new PCB fit in the product?
• Do you have additional ideas?

And then automate all these so they run continually. This takes the tedium out of testing and helps ensure every development change is a BIG Release.
