@albertandrejev I would like you to do this ticket because you are going to practice how to implement DOM tests using Jests. But the send token one let me take care of it.

Let me know when you start with it.

@ethanfrey can you help me please. I can not understand what to test in "login (return to page)", what "return to page" means?

Sorry, unclear notes.
Ideally, you can create a redux store and create a profile (using an action).
Then go to the home page with that same store (in dom) and you should be directed to login page, then the set username page, then balance... (like the signup test but a different start)
