Fix: Resolve all 7 flaky E2E tests in AppHost.Tests (#96) - #102
Conversation
- Create ADR-002 documenting the two-layer CQRS handler pattern - Domain/Features contains pure business logic handlers (no infrastructure) - Web/Features contains application orchestration handlers (caching, DTOs, error handling) - Clarifies that this is NOT a VSA violation due to clean layer separation - Explains rationale: testability, extensibility, separation of concerns - Update ARCHITECTURE.md with two-layer pattern section - Update solution structure to reflect Domain/Features presence - Update ADR table with new ADR-002 reference Fixes #97 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Root cause analysis and fixes: - Added missing /test/login endpoint for E2E test authentication (Tests were failing because auth state wasn't being set up) - Fixed AuthorizeView rendering by using LoadState.NetworkIdle instead of DOMContentLoaded for interactive Blazor components - Fixed NavLink brand href from empty string to '/' to match test selectors - Fixed login/logout href casing to match case-sensitive CSS selectors - Added <header> wrapper around <nav> in NavMenu for semantic HTML - Added role='contentinfo' to footer for accessibility tests - Updated theme component aria-labels for consistent test selectors Test results: - All 20 E2E tests passing (up from 13/20) - All 59 bUnit tests passing - All 84 Web unit tests passing - Zero regressions across full test suite - Verified 3 consecutive stable runs Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
Resolves flakiness in AppHost Playwright E2E tests by adding a test-only auth shortcut, aligning layout semantics/selectors, and documenting the Domain/Web dual-handler CQRS architecture.
Changes:
- Added a Development/Testing-only
/test/loginendpoint to support cookie-based auth in E2E runs. - Updated layout components (NavMenu/MainLayout + theme controls) to stabilize selectors and improve semantic HTML.
- Updated Playwright layout tests and added/updated architecture documentation (ADR-002 + ARCHITECTURE.md).

Hard-coding a 5s timeout for WaitForAsync can reintroduce flakiness in CI (cold starts / hydration often exceed 5s). Prefer Playwright’s default timeout, a shared higher timeout constant, or waiting on a more deterministic condition.

Markdown validation rules in this repo specify not to use an H1 heading (the title is provided via front matter). This file includes both post_title and a # ... H1, which may fail validation; change the first heading to ## and keep the rest of the hierarchy aligned.

In the test login endpoint, role can be whitespace (e.g., ?role= ) but string.IsNullOrEmpty will treat it as a valid role and emit a whitespace Role claim. Use string.IsNullOrWhiteSpace (and ideally restrict to a small allow-list like user/admin/author) before creating the role claim.

<ThemeSelector /> is present in the desktop nav but was removed from the mobile menu. This is a functional regression for small screens (users lose the ability to change theme when the hamburger menu is open). Consider adding the theme selector (or equivalent controls) back into the mobile menu section as well.

This only asserts that the profile link is absent; it would also pass if the entire nav failed to render. Consider also asserting that an expected public link (e.g., "Blog Posts") is present/visible so the test meaningfully validates anonymous navigation.

The header login/logout links now use lowercase /account/login and /account/logout, but the mapped minimal API endpoints are defined as /Account/Login and /Account/Logout (see earlier in Program.cs). While routing is case-insensitive, this casing mismatch has already caused case-sensitive selector issues in Playwright. Consider standardizing the endpoint paths (and any other code that navigates to them) to the same casing used in the UI/tests.

The mobile "Home" NavLink still uses href="", which can resolve to the current route rather than / and is inconsistent with the desktop brand link. Set it explicitly to / to avoid surprising navigation and keep selectors consistent.

## Sprint 4 Release — v1.1.0 Replaces PR #105 which had a merge conflict in workflow files (`squad-ci.yml`, `squad-test.yml`). ### Changes included All Sprint 4 work from `dev`: - feat: Blazor theme system (Sprint 4 issues #81–#86) - feat: VSA migration — move Domain.Features to Web (PR #104) - fix: Resolve all 7 flaky E2E tests in AppHost.Tests (PR #102) - refactor: Reorganize test projects (PR #100) - ci: Central Package Management (CPM) - ci: Fix squad-preview validate to skip AppHost.Tests/Bunit (unrunnable on plain runners) ### Conflict resolution `squad-ci.yml` and `squad-test.yml` had add/add and content conflicts from main having an older version. Resolved by accepting the `dev` versions (correct current state). --- Closes #105 _After merging, run **squad-milestone-release** to tag and publish v1.1.0._
Summary
Fixed all 7 flaky E2E tests in AppHost.Tests by identifying and addressing root causes related to authentication setup, Blazor component rendering, and test selectors.
Root Causes Identified
Missing test login endpoint - The
/test/login?role=userendpoint referenced in tests didn't exist, causing auth state to never be set up.Blazor rendermode timing issues - Tests using
LoadState.DOMContentLoadedfired before InteractiveServer components initialized. Changed toLoadState.NetworkIdle.Href mismatches - NavLink brand href was empty string instead of '/'. Login/logout hrefs had mixed case that didn't match case-sensitive selectors.
Missing semantic HTML - NavMenu lacked header wrapper. Footer was missing contentinfo role.
Test selector mismatches - Theme selector is select element, test was looking for button.
