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!
