            Bug ID: 244244
           Summary: [WPE][GTK] Support for headless testing with weston
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org

Currently we go through a convoluted setup of running weston in Xvfb, while we could simply use the weston headless backend.

Doesn't work in GTK yet though, hitting some a11y-related critical warning:
