Hello!
Well then, according to the latest Codecov report, it seems that my tests are finally complete ^^
@pierre-gilles If you see anything missing, I’m waiting for your feedback, otherwise, for me, everything is good for a first version 
I also wanted to say thank you! Given that this is my first « real » dev in Node and Preact, I admit I was a bit lost at times. So thank you for your patience, and I look forward to seeing the result of several dev evenings becoming an integral part of Gladys 4
