title: how properly mock multiple useSelector hooks
body: <p>my component has multiple selectors:</p>
  <pre><code>import { useSelector } from 'react-redux'
  ...
  const data1 = useSelector(xxxxx)
  const data2 = useSelector(yyyyy)
  </code></pre>
  <p>How properly mock each in test file?</p>
  <pre><code>import { useSelector } from 'react-redux'
  jest.mock('react-redux', () =&gt; ({
      useSelector: jest.fn()
  }))
  ....
  useSelector.mockImplementation(() =&gt; ({
     dataready: true
  }))
  </code></pre>
  <p>which selector it's really mocking in this case?</p>
