I'm doing a side project where I'm working on improving a couple of git's man pages and could really use a few test readers. if you're interested, sign up here!
I'd especially love test readers who use git on the command line regularly but are not 100% comfortable with it

So, let's see what we've learned so far.
"A.I." coding assistants produce better results ("value earned/tokens burned") when you:
* prompt with tests
* work in small feedback cycles with continuous testing, code review, refactoring and integration
* cleanly separate concerns in your code
LOL

Most bugs aren’t coding errors.
They’re misunderstandings.
Acceptance Test-Driven Development (ATDD) fixes that—by aligning devs, testers & stakeholders before code is written.
Fewer bugs. Faster feedback. Better software.

TDD is a threat in The Desert. Programmers are asked to take responsibility for reliability. They know they will slow down in the short run & be blamed for it. They know they will not be given time, tools, or training. It's just more work & more potential negative consequences. #ForestAndDesert

You’ll notice that “test coverage” is not one of the desirable properties of tests in testdesiderata.com.
Coverage by itself means nothing. Lack of coverage means something but increasing coverage doesn’t necessarily mean anything.
