Test expects the cookies store return non empty string from browser.evaluate("return document.cookie;"), the expectation was changed during 2902061.

The test doesn't fail locally for me.

I wonder if that somehow relates to the fact that test uses https://www.eclipse.org/swt which currently automatically redirects to https://eclipse.dev/eclipse/swt/, maybe cookie is not set/set later on/cleared due redirect in webkit.

See #2810

I think the issue is running inside the EF network, if I run some curl commands, you can see the one for eclipse.dev fails (see this CI job):

If this is a recent regression (it appears to be about a week old) I would guess that EF changed their network config.

I'll raise a ticket on helpdesk now.
