Preemptive commit comments

tl;dr version

Rule #1: write commit comments before coding
Rule #2: write what the software should be supposed to do, not what you did

You won’t believe how old TDD is

Kent Beck is credited as the TDD inventor.
Yet, he claims he just re-discovered it.

Help me, because I think Martin Fowler has a Merge Paranoia

There must be something very wrong with me: for the first time in my life I think that Martin Fowler is wrong on a specific topic. And, since Martin is Martin and I’m just a humble developer (Arialdo who?) I’m likely to be the one who’s completely off the track.Nevertheless, unfortunately, no matter how much I dig into the topic, I’m not able to convince myself that Martin Fowler’s arguments about Feature Branching, Continuous Integration and Feature Toggling are right.

Please, help me to understand what I’m missing.

Unit tests lie: that’s why I love them

When a unit test for a method implementing some feature is green, it does not mean the feature is working. The corresponding end-to-end or integration tests reveal if it’s working or if it’s broken. To Product Owner’s point of view, end-to-end tests are all that matters. Unit tests are useless.

Unit tests are meant to lie. They rely on the often wrong assumption that the rest of the world is correctly working, but only because they are explicitly mocking it: using a fake world is a deliberate lie.

To me, that’s exactly why they are so useful.
