How to check redux action is working?
and as a result of the execution, check the dataState for the presence of data?

For example:

Test the authorization function in the application.
expect(AuthMethod(login, password));

Answer 1

const store = Redux.createStore(yourReducer)
store.dispatch(AuthMethod(login, password))
const value = store.getState().someKey // вместо someKey нужный вам ключ

And then you compare value with the expected value
