Installation

npm install

Recreating the bug

Run:

npm test

Expected result: The test passes and the console logs componentDidUpdate

What actually happens: The test fails and nothing is logged from lifecycle methods

Other test scenarios

Open scripts/Foo.test.jsx and uncomment the other test scenarios. These work as expected. There are two other scenarios:

1. Using mount to render the component
2. Using shallow to render the component and passing in lifecycleExperimental: true as an option (which should be the default according to the docs)
