A React component - even just a basic one that renders “Hello World” for now.
A server which spits back our basic React component after it’s wrapped it in some HTML structure.
A React app which is going to pick up from where the server rendered HTML left off and add in any event listeners to the existing markup where needed.
It’s important to note here that, for React’s sake, what you render on the server (#2 above) needs to be identical to what is rendered on the client (#3). If not, React will throw a warning.

What is unit testing?
Break down the project into small pieces
Test them independently

- Repeatable
- Atomic
- Fast
- Isolated / Independent
- Descriptive
- well structured
