@commjoen I hope it passes all the tests now :)

we still have an issue:

error: unable to forward port because pod is not running. Current status=Pending
Error from server (NotFound): services "prometheus-server" not found
Error from server (NotFound): services "grafana" not found

alternatively you can try to maek it all part of one shell script where you do the ready-check and then start cypress maybe? would that make it simpler?

Hi @commjoen,

Thank you for your patience and guidance. I've pushed a final, clean update to this pull request that should resolve all the failing checks.

Following your advice, this new version now uses a single, robust shell script (scripts/run-e2e-tests.sh) to manage the entire test process (deploying the app, waiting for it to be ready, and running the Cypress tests) in the CI environment.

This pull request now contains the complete and working Cypress tests, the new test script, and the simplified GitHub Action workflow. All tests are passing on my local machine. This should be ready for a final review. Thanks!

The new one is #972
