Class 22 Reading: React Testing and Deployment

Describe a case where snapshot testing would be useful, and describe another case where it would be ineffective.

One case where snapsjot testing would be useful is when you are changing up the back-end of an existing project and want to ensure the front end still rendered the same way after you made your changes. A scenario where it would be ineffective would be if you were updating the front end of the site. (This would change the rendered html and the snapshot would not match)

What is the difference between full mount and shallow mount?

Full mount testing is where a component and all its children are rendered to be tested. With shallow mount testing, only the current component is rendered and all its required dependencies are left out to just test the function of the current component.

What does npm run build do?

NPM build is a command that creates a production ready version of your code that you can deploy to a website. The production ready code includes static files with the compiled JS and CSS files as well as the rendered HTML pages.
