Improve Cypress testing suite

[bdbch]

What’s the bug you are facing?

Currently our Cypress test suite is running on Github CI and take around 30 minutes to finish. Those are currently running on all branches and on each commit. Also tests are failing randomly because the headless browser is not finding specific elements which should be there after the grace time of 10s.

Open Tasks

• Adjust Github CI
  • Only run on main and release-* branches
  • Only run on PRs when a PR was approved
• Refactor tests to run more performant
• Fix performance issues in combination with Github CI and the headless browser

Other notes

We also thought about adding unit tests specifically for the core and ui library packages to test helper and core functions and classes which could run more frequently.

Testing specific frameworks would also be a nice addition as a test on release-* branches so we can test if Tiptap is correctly installed in various setups.

Those could include

• Next.js
• CRA
• Vite
• Nuxt
• Vanilla Webpack

This could avoid future issues with broken builds with said frameworks.
