Test connections via workers instead of the API server

Was generative AI tooling used to co-author this PR?

• Yes (please specify the tool below)

Follow-up to #62343, which moved connection testing to workers but left the UI on the old sync endpoint.

This wires the Connections "Test" button to the new worker flow: enqueue the test, then poll until it finishes. The result shows up as a toast (with the worker's message) and the usual green/red icon. Clicking Test while one is already running shows an "already in progress" message.

Thanks for the PR, tested and working as expected.

I don't think we can do this before all executor support the async connection testing flow. Otherwise it will just break the feature for people using the celery executor for instance.

We also need to update the documentation, for instance here /Users/pierrejeambrun/Documents/astronomer/git-repositories/airflow-agents/agent-1/airflow-core/docs/howto/connection.rst,

When testing in the Airflow UI, the test executes from the webserver so this feature is subject to network egress rules setup for your webserver.

For security reasons, the test connection functionality is disabled by default across Airflow UI, API

Etc...

Also a few suggestions / comments.

@pierrejeambrun thank you so much for the review. I have addressed the feedback relating to this pr. And thank you very much for pointing out the executor work for supporting async connection. I will covert this pr to draft for now and will start working on the executor work.

thank you

🛠️ Maintainer triage note for @anishgirianish · by @potiuk · 2026-07-08 16:05 UTC

This draft has been inactive for ~16 days, so I'm closing it to keep the review queue tidy — no judgment on the work itself.

No rush — reopen it (or open a fresh PR) whenever you're ready to continue; nothing is lost.

Not stale, it just needs some other preliminary work on the executors before it can go through
