Writing tests is often not the most enjoyable task for developers. In this post, we delve into the challenges of testing and take the first step toward addressing them: mastering the basics. whattt.substack.com/p/write-tests-…

Let's face it: For many developers, writing tests is more of a chore than a joy. But what if it didn't have to be? In this series, we dive into the common frustrations with unit testing and introduce an alternative approach we've embraced at @chrono24. We'll show you how to transform testing from a tedious task into an integral, effective part of your workflow. Our goal is to make your tests not just bearable, but genuinely beneficial.

Tech companies use different names for the same position. Which one do you prefer?

I do not do Scrum, so I have no need to estimate an increment/Sprint. I just work on the most valuable single story next. I pull that story, narrow it down to a set of <= 2-day stories, pick the most valuable (of the most valuable 😄), and build that. 1/3
