// But you probably weren't even testing the "container" component that this
// replaces :O

// if you want to still have a "container" v. "view" split and only test the
// "views" like you currently do, use it like this in the App:
const Expenses = () => (
  // here's your old container HOC
  <ExpensesContainer render={(expenses) => (
    // Here's your old "view"
    <ExpensesView expenses={expenses}/>
  )}/>
)

export default Expenses
export ExpensesView

// And then only test ExpensesView just like before, but with render props,
// there's not usually a file that exports both of these, the coupling usually
// goes away. It's one of those questions that gets eliminated.
