Have we confused “clean code” with tidy code, and forgotten that the real test is behaviour under change?

I prefer "Test Double".
We use them to emulate dependencies without depending upon the dependencies.
I've seen some tests that only seemed to test the mock!?

Somewhere along the way, our industry started calling everything a mock.
@emilybache.com explores why the language of mocking in software testing has drifted so far from its original meaning.

Looking forward to Emily's video tonight on mock language confusion... time we all agreed what the term "mock" actually means to software engineers.
First video of 2026, after a break on @modernswe.bsky.social over the holidays.
Tune in for more excellent stuff from @emilybache.com!

AI can ASSIST your deployment pipeline, but it must never be allowed to define it. If you don’t understand how your pipeline works end-to-end, you’re doing hope-driven delivery.

Just listened to this episode of The Engineering Room with @charity.wtf and @davefarley77.bsky.social, extremely good! This part on managers being “shit umbrellas” hit home catastrophically for me. So rare (IME) for management to treat their underlings as adults.

Vibe coding might sound trendy, but I think vibe coding might be one of the worst ideas in software engineering and software development in 2025...

"Don't guard your code, improve it together"
It's hard to let go of your code being an extension of you, and so it's hard to accept that suggestions about your code is not a critique of you. Once you can get past this then you can improve with feedback so much more.
