Failing Test(s)

Microsoft.AspNetCore.Components.E2ETest.ServerRenderingTests.RedirectionTest.NavigationException_InAsyncContext_DoesNotBecomeUnobservedTaskException

Error Message

Error details unavailable — this test runs in the components-e2e pipeline (pipeline 87) which executes E2E tests directly on CI agents without Helix infrastructure, so per-test error logs are not accessible via the public API.

Stacktrace

Re-quarantine Investigation

This test was unquarantined on 2026-03-27 (PR #65998) but has since been failing again, with 2 failures observed in the components-e2e pipeline (definition 87, build 1363898).

Test Description

The test navigates to a circular redirect page and verifies that the resulting NavigationException (thrown internally during rendering) does not become an unobserved task exception:

public void NavigationException_InAsyncContext_DoesNotBecomeUnobservedTaskException()
{
    AppContext.SetSwitch("Microsoft.AspNetCore.Components.Endpoints.NavigationManager.DisableThrowNavigationException", false);
    Navigate($"{ServerPathBase}/redirect/circular");
    Browser.Equal("0", () => Browser.FindElement(By.Id("unobserved-exceptions-count")).Text);
}

Failure Analysis

Detailed error logs are not available from the components-e2e pipeline via the public API (these tests run directly on CI agents, not via Helix). However, the likely failure modes are:

1. Timing flakiness: The Browser.Equal() assertion may time out waiting for the unobserved exceptions counter to appear or stabilize on the page. Circular redirects involve multiple round-trips and rendering cycles before the page settles.

2. Navigation state race: The circular redirect logic may not complete its 3 retry attempts within the expected time window, causing the element to not be rendered when the assertion runs.

3. AppContext switch interaction: The AppContext.SetSwitch at the start of the test modifies global state. If tests run in parallel or if cleanup from a prior test is incomplete, this could affect behavior.

Recommendation

Review whether the circular redirect page rendering stabilizes quickly enough for the Browser.Equal poll to succeed within its default timeout. Consider adding a longer timeout or a more explicit wait for the redirect cycle to complete before checking the counter element.
