-export default connect(state => ({ count: state.count }))(Counter)

-
-For this example, we'll have a simple reducer that tracks and updates `count`:
-
-```js
-// reducer.js
-export const initialState = {
-  count: 0,
-}
-
-export function reducer(state = initialState, action) {
-  switch (action.type) {
-    case 'INCREMENT':
-      return {
-        count: state.count + 1,
-      }
-    case 'DECREMENT':
-      return {
-        count: state.count - 1,
-      }
-    default:
-      return state
-  }
-}
-```
-
-To test our connected component we can create a custom `render` function using
-the `wrapper` option as explained in the
-[setup](./react-testing-library/setup.md) page.  
-Our custom `render` function can look like this:
-
-```js
-// test-utils.js
-import React from 'react'
-import { render as rtlRender } from '@testing-library/react'
-import { createStore } from 'redux'
-import { Provider } from 'react-redux'
-import { initialState as reducerInitialState, reducer } from './reducer'
-
-function render(
-  ui,
-  {
-    initialState = reducerInitialState,
-    store = createStore(reducer, initialState),
-    ...renderOptions
-  } = {}
-) {
-  function Wrapper({ children }) {
-    return <Provider store={store}>{children}</Provider>
-  }
-  return rtlRender(ui, { wrapper: Wrapper, ...renderOptions })
-}
-
-// re-export everything
-export * from '@testing-library/react'
-
-// override render method
-export { render }
-```
-
-```jsx
-// counter.test.js
-import React from 'react'
-import { createStore } from 'redux'
-// We're using our own custom render function and not RTL's render
-// our custom utils also re-export everything from RTL
-// so we can import fireEvent and screen here as well
-import { render, fireEvent, screen } from './test-utils'
-import '@testing-library/jest-dom/extend-expect'
-import Counter from './counter'
-
-test('can render with redux with defaults', () => {
-  render(<Counter />)
-  fireEvent.click(screen.getByText('+'))
-  expect(screen.getByTestId('count-value')).toHaveTextContent('1')
-})
-
-test('can render with redux with custom initial state', () => {
-  render(<Counter />, {
-    initialState: { count: 3 },
-  })
-  fireEvent.click(screen.getByText('-'))
-  expect(screen.getByTestId('count-value')).toHaveTextContent('2')
-})
-
-test('can render with redux with custom store', () => {
-  // this is a silly store that can never be changed
-  const store = createStore(() => ({ count: 1000 }))
-  render(<Counter />, {
-    store,
-  })
-  fireEvent.click(screen.getByText('+'))
-  expect(screen.getByTestId('count-value')).toHaveTextContent('1000')
-  fireEvent.click(screen.getByText('-'))
-  expect(screen.getByTestId('count-value')).toHaveTextContent('1000')
