With Cypress, you can easily create tests for your modern web applications, debug them visually, and automatically run them in your continuous integration builds.

I tried to do that and ran into problems. The first problem was the port -- npm started my server on 5173, and cypress was expecting 4173. I tried to adjust the ports by using these commands:
```
npm run dev -- --port 4173
npx cypress open -- --port 4173
```
the warning that I saw before disappeared, so it seemed like that had resolved the port issue
