[hw3] should we use enzyme-adapter-react-16? #96

I ran into a problem where if I use mount() on a component then an error occurs. It says TypeError: Cannot read property 'child' of undefined. After searching, I found that it may occur because the react version 17.0.2 and enzyme-adapter-react-16 conflicts.

In the swpp-unittest-tutorial from the practice session, I found that enzyme-adapter-react-17-updated was used instead of enzyme-adapter-react-16, and there were no problems in using mount(). Can I change my package.json file so that I use enzyme-adapter-react-17-updated?

Yes, you can change the package.json to use enzyme-adapter-react-17-updated.
