In post 4 (Testing) we established a testing strategy for our app that leveraged Enzyme. In post 6 (Lazy Loading) we decided to upgrade to React 16.7 (alpha) to take advantage of (and to experiment with) some of the new features of React. This broken out tests, per https://github.com/airbnb/enzyme/issues/1917. As a result, we decided to move away from Enzyme and move to react-testing-library.
