Tests are like a crying baby. They don't tell you why, but you'd better listen.

The goal of these initiatives, said Nejatian, is to “change the default answer from yes to no.” A interesting take on meetings fortune.com/2023/07/12/remot…

Shopify's crusade against Zoom meetings now includes a cost calculator: 'Most of the modern work...

COO Kaz Nejatian has built a calculator to wake employees up to how much they're costing the company. A typical half-hour meeting runs from $700 to $1,600.

I had the chance to participate in a doc-as-test workshop at #breizcamp by @sebfauvel The idea is to use the documentation as a primary source for our tests. I absolutely recommend it sfauvel.github.io/documentat…

It uses approval tests by @LlewellynFalco in new way And it somehow reminds me about TextTest that @emilybache introduced me to.

It creates bits of asciidoc that can then be assembled, possibly in various ways.

Les slides de "3P pour sortir du legacy" à #breizcamp speakerdeck.com/martinsson/3…

3P (Protect-Prepare-Produce) to get out of Legacy - BreizCamp

When you write tests or refactor at the end of a story, or worse in a separate story, who gets the benefits? And when? Unfortunately it's the next …

Why small steps? I was discussing with colleague what would be the interest of coding a story with several mergeable steps (i.e. non breaking changes) One reason is Options ⏬ I made this viz while discussing, though I'd share it

One counter-point that was advanced is that, in particular, without tests it's too costly to stabilise every small step. Indeed that is true, but just because you have the option of stabilising with some manual tests doesn't mean you have to. That's what an Option is about.

This is a benefit that is valuable even when working alone on something When working in a team on the other hand there are a load of other benefits, like no merge hell, more opportunistic refactoring, etc. But that'd be a subject of some future thread

Excited to be on my way to @breizhcamp! I'll be promoting crappy 💩 tests as a part of 3P (Protect - Prepare - Produce), my favorite legacy mitigation technique.

Kent Beck on cost of software: Cost(software) ~= Cost(change) Cost(change)=cost(coupling) Reducing that also requires decoupling Cost(software) = cost(coupling) + cost(decoupling) #DDDEU

Decoupling ~= increasing cohesion Cohesion = Grouping of coupled elements i.e. Cohesion = Copling(e1, e2, ..) Meaning that we optimise the span of coupling so that things are closer together All from the great goodreads.com/book/show/5784…

Finally adding that when doing a behavioural change. We must consider separating into a stuctural change (refactoring) and behavioural change. Iteratively, of course.
