Failing Test(s)

Microsoft.AspNetCore.Components.E2ETests.ServerRenderingTests.EnhancedNavigationTest.NavigationManagerUriGetsUpdatedOnEnhancedNavigation_OnlyServerOrWebAssembly

Symptoms

Test has failed 2 times in the components-e2e pipeline (definition 87) over the last 30 days.

Error message:

Assert.EndsWith() Failure
Expected: /nav/location-changed/server?query=1
Actual:   /nav/location-changed/server

The test performs enhanced navigation and asserts that NavigationManager.Uri is updated with the full URL including query string. On failure, the URL is captured before the query string parameter has been appended, indicating a timing/race condition in the enhanced navigation flow.

Investigation

Pipeline: components-e2e (definition 87), refs/heads/main

Failure count: 2 failures over the last 30 days

Error message

Actual:   /nav/location-changed/server

Root cause analysis

The test NavigationManagerUriGetsUpdatedOnEnhancedNavigation_OnlyServerOrWebAssembly:

1. Navigates to a page with a LocationChanged event component
2. Navigates again with a ?query=1 parameter
3. Asserts that NavigationManager.Uri ends with the full URL including the query string

On failure, the URI is captured before the enhanced navigation completes and the LocationChanged event fires with the updated URI. The test sees the intermediate state (path without query string) before the final state stabilizes.

This is an E2E timing race between the enhanced navigation completing and the DOM being updated with the new NavigationManager.Uri value.
