Notes

It sometimes makes sense to test React hooks and contexts separately, however most of their behaviour in this app has been tested implicily with existing tests!
The app requires some testing of the navigation stack itself -- this was non-trivial to achieve quickly with the alpha release of react-navigation alpha I decided to play with.
Following from above, App.js still requires some basic testing.
End-to-end testing could solve the above using Detox or Appium and more time.
