🚀 Senior Software Engineer | Barcelona, Spain 🌍 🛠️After several years of experience developing APIs in high-traffic environments and learning about testing, best practices, architecture, and more with PHP, I changed to Kotlin because the programming language is just a tool that allows us to give value to our users. 🎤 Sharing knowledge is one of my passions. I’ve participated in different online and in-person events talking about testing, also taught about it at university for three years, as well as architecture and best practices. Those are topics that I also share with my teammates. 👩🏻‍💻 After starting with Kotlin, I also create a couple of courses on how to start with Kotlin and develop an API following ports&adapters architecture with Kotlin. 🌟In recent years, I joined Step4ward as a mentor and now as a co-organizer, a community dedicated to helping grow and succeed women in technical careers.

The T in FIRST didn't mean Thorough originally. The T was for Timely.

There's a post by Tim Ottinger on his blog "Tim Ottinger's thoughts on Software Development" that explains the history of the FIRST acronym:

FIRST: an idea that ran away from home

Google it because it seems that as a new users I can't add inks in comments.

I agree with you. I think that I, R and S can be applied to other type of tests other than unit-tests.

I liked your post. Thank you!

Yes [Manuel Rivero](https://hashnode.com/@trikitrok) you are absolutly right, it took me some time until I found the original definition for FIRST [agileinaflash.blogspot.com/2009/02/first.html](https://agileinaflash.blogspot.com/2009/02/first.html) I'll update it here to correct it :) I´m glad you like the post!
