The Context-Builder pattern is a structural testing pattern used with the MSpec BDD framework. Its central purpose is to keep spec classes (the things you read when understanding system behaviour) free of construction noise — the boilerplate of creating fakes, wiring them together, and assembling the subject under test — while still making that construction easy to follow in a dedicated place.

/ A Crusade For Open Source Designers to Release Their Original CAD Models.md
Created
September 18, 2022 16:41
I'm on a bit of a crusade to persuade designers of open-source models to include their original CAD models.
There seems to be a trend of including a STEP file and calling it a day. While that has uses, it is only a partial solution and does not represent the "source code", so arguably an open source design must have the original CAD model included.
I am aware that to some people this may appear as if I am being "ungrateful" and truly that is not the case. I am grateful for all the wonderful free models. I am, though, enthusiastic about the idea of remixing, improving, and building upon those ideas. I suspect that many people think that the STEP file is enough for this, but it really isn't, for several reasons.
