@foodaka @JoaquinBattilana Am i using the correct workflow by forking the repo, then submitting a pr back to main repo. Let me know if there is anything else i'm missing in this pr. I want to dive deeper into Aave repo and become a regular contributor. Thanks

@kodakyellow you can follow the contributing guidelines here https://github.com/aave/interface/blob/main/CONTRIBUTING.md , thanks for the contribution

thank you, this pr came from a forked repo as the guidelines have stated. However, I was not able to follow the guidline for naming branche since this pr didn't resolve any bug issue or add new features, instead i looked for low hanging fruits like adding some tests in this pr (since its my first pr for this repo). The changes are ready for review. Thanks cc @foodaka
