Code testing

[krzysztof-kwitt]

Hello,

I noticed that the code currently has no tests, which makes development difficult. I know that writing tests and maintaining them is an additional effort, but I think that in the long run it will allow us to add new changes faster.

What do you think to add to start working on them?,This requires that we agree on the approach and what tools we want to use to do this.

What do you think about start testing individual components using @testing-library/react and jest? I think this is common setup in the React world.
