It’d be interesting to validate that empirically

The number of assertions per test is power law distributed.

Continuing my series of posts attempting to (pseudo-)formalise the practice of Test-Driven Development, I want to look at a “rule” of TDD that’s actually helpful whether you’re going test-first or test-after.

I haven’t. I’ll check it out. Thanks.

I often say "augmented development" to capture exactly this.

Correct

It's happening to me sooner & more. I had a bug that I kept having the genie fix in various places. I had to insist that the genie remove the duplication. Then the fix stuck.

Or even no designing thinking ever at all.

Disagree. The only destination in the pool is the other end of the pool.

Kent Beck @kentbeck.com · 27d

Augmented coding is like ocean swimming vs pool swimming. In the pool you have straight lines & plenty of feedback. In the ocean you have to pop your head up & see where you're going periodically to actually make progress towards a goal. More strokes faster isn't going to get you there faster.

Those factors establish the lower bound on team size.

Kent Beck @kentbeck.com · 29d

Not necessarily smaller stuff. Just 4 programmers instead of 12. (We can talk later about where the other 8 programmers go.)

Augmented coding prediction--we're going to see team sizes shrink. XP has been dealing with this for 25 years, so g'head & ask if you'd like to know what comes next.

When I am elected, I will read the code DOGE wrote. I will find out how they stole your data and what they have done with it.

And then I will tell you

Running tests contains a fundamental information asymmetry seemingly ignored by most test runners. Test passes? NBD Information value much less than one bit. At most, increment some counter you'll show me later.

When a test fails, though, that's a big deal! Show me that for sure.

Both problems solved--do (or at least consider doing) what your furious critic demanded. Not all of it, not just yet, but enough to unblock them.

3X Explore/Expand/Extract observation--criticism as a resource. I tried to use a tool yesterday & was angry when it didn't (yet) work for me.

If you're Exploring & a user gets mad, that's such a gift. Just yesterday you a) didn't know quite what to do & b) weren't sure anyone cared what you did.

My favorite part of running so far is connecting with skeptics.

People have a picture in their head of a “trans socialist”. It isn’t usually a curious motorcycle-riding homeowner with a pickup truck who is nearly impossible to offend.

That moment of confusion can be the start of a conversation.

If your most effective management skill is insisting people work 80 hours a week, you might want to consider learning some new management skills.
