The 'Not enough traffic yet to display stats' notification not appearing on Entity Dashboard

[wpdarren]

Bug Description

The Not enough traffic yet to display stats desktop notification only appears on the main dashboard. When visiting the entity dashboard for a specific page, the notification does not appear when in zero data state. I believe that it should.

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• Zero data state notifications should appear on the entity dashboard, as well as on the main dashboard

Implementation Brief

• Create a new EntityBannerNotifications component as an entity dashboard-specific variant of the current BannerNotifications component
  • For now this would only include ZeroDataStateNotifications in the same way as it is in BannerNotifications
• Update DashboardEntityApp to render the new EntityBannerNotifications component in the subHeader prop of the Header component, similar to DashboardMainApp

Test Coverage

• No changes needed

QA Brief

• Ensure zeroDataStates feature flag is enabled.
• Using the tester plugin, enable the zero data state for Analytics and Search Console.
• Clear the session and reload the page.
• Ensure the Zero data state notification appears.
• Type Sample Page in the entity search input.
• Click the search results and go to the entity dashboard.
• Ensure the Zero data state notification appears as it appears in the main dashboard.

Changelog entry

• Add "gathering data" and "zero data" headers to single URL ("entity") dashboard pages.

Works for me! IB ✅

QA Update: ✅

Using the tester plugin, with zero data state for Analytics and Search Console:

• The Zero data state notification appears on the main and entity dashboard.
• Checked that the notifications appeared as expected on smaller screensizes.

Screenshots

QA note: When you have search console in gathering and analytics in zero (and vice versa) the notification doesn't appear on main or entity dashboard. This was discovered while QA-ing 5008 and is currently being fixed.

Will retest this when that ticket is back in QA.
