Improve your testing skills by asking yourself the foundations that make testing work.
Every developer has faced that moment of doubt: “Why am I writing tests for code I know works?” Rather than being a problem, this question is the first step towards the mastery of software testing. So, let’s explore together and learn how to improve testing, from the moment of doubt in which testing seems futile, to the moment in which it seems the most useful technique ever.

A decade ago, I used to go to testing meetups because I wanted to learn. Honestly, I wanted to learn, but the more I heard, the less useful I found it. And, which is the best part of meetups?
