[Feature] Write unit tests

[eduardconstantin]

Is your feature request related to a problem? Please describe.
This web app doesn't have any unit test written.

Describe the solution you'd like
Use jest to write some unit tests.
It does not have to be 100% coverage, new issues can be created to improve it.

I don't know about testing. Can you provide me with some guidance and references so that I can learn and address this issue? At least, I will learn something.

You need to install jest first - https://jestjs.io
Then you can create a test folder to have a place for all the tests
You can find here some tests I wrote for the components
You can try to write a test for the theme switcher
