Phase 2 Plan 6: PermissionsViewModel and SitePickerDialog Summary

PermissionsViewModel orchestrates multi-site CSOM permission scans with TDD-verified scan loop, CSV/HTML export commands, and SitePickerDialog for multi-site selection via factory pattern

Performance

• Duration: 4 min
• Started: 2026-04-02T12:02:49Z
• Completed: 2026-04-02T12:06:55Z
• Tasks: 2
• Files modified: 6

Accomplishments

• PermissionsViewModel fully implements FeatureViewModelBase with scan loop, export, and tenant-switch reset
• SitePickerDialog XAML + code-behind: filterable ListView with checkboxes, loads via ISiteListService on Window.Loaded
• ISessionManager interface extracted so ViewModels can be unit-tested without live MSAL/SharePoint
• TDD: RED→GREEN cycle with StartScanAsync_WithMultipleSiteUrls_CallsServiceOncePerUrl passing; 60/60 tests pass

Task Commits

Each task was committed atomically:

1. Task 1 RED: Failing test for PermissionsViewModel - c462a0b (test)
2. Task 1 GREEN + Task 2: Full PermissionsViewModel and SitePickerDialog - f98ca60 (feat)

Files Created/Modified

• SharepointToolbox/ViewModels/Tabs/PermissionsViewModel.cs - Feature orchestrator: scan loop, export commands, dialog factory, tenant switch
• SharepointToolbox/Views/Dialogs/SitePickerDialog.xaml - Multi-site picker: filterable list with CheckBox + Title + URL columns
• SharepointToolbox/Views/Dialogs/SitePickerDialog.xaml.cs - Code-behind: loads sites on Loaded, exposes SelectedUrls, filter/select-all/deselect-all
• SharepointToolbox/Services/ISessionManager.cs - Interface for SessionManager (new)
• SharepointToolbox/Services/SessionManager.cs - Now implements ISessionManager
• SharepointToolbox.Tests/ViewModels/PermissionsViewModelTests.cs - Real test replacing the previous stub

Decisions Made

• ISessionManager extracted — SessionManager is a concrete class with MSAL dependencies; interface required to mock it in unit tests. Matches "extract interface for testability" pattern from Phase 1 (IPermissionsService, ISiteListService already existed).
• Test constructor — Internal constructor omits CsvExportService and HtmlExportService since export commands are not exercised in the scan loop test. Keeps tests lean.
• Dispatcher null-guard — Application.Current?.Dispatcher is null in xUnit test context (no WPF thread). Guard ensures Results assignment succeeds in both test and production contexts.

Deviations from Plan

Auto-fixed Issues

1. [Rule 2 - Missing Critical] ISessionManager interface extracted for testability

• Found during: Task 1 (PermissionsViewModel TDD setup)
• Issue: Plan specified injecting concrete SessionManager. Moq cannot mock concrete classes without virtual methods; unit test required a mockable abstraction.
• Fix: Created ISessionManager interface with GetOrCreateContextAsync, ClearSessionAsync, IsAuthenticated; SessionManager implements it.
• Files modified: SharepointToolbox/Services/ISessionManager.cs (new), SharepointToolbox/Services/SessionManager.cs
• Verification: Build succeeds, existing 60 tests still pass
• Committed in: c462a0b (RED phase commit)

---

Total deviations: 1 auto-fixed (1 missing critical) Impact on plan: Required for correct testability. SessionManager DI registration changes to services.AddSingleton<ISessionManager, SessionManager>() — handled in Plan 07.

Issues Encountered

None — plan executed as written with one necessary interface extraction for testability.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• PermissionsViewModel and SitePickerDialog complete — all business logic for Permissions tab is done
• Plan 07 (DI wiring) must: register ISessionManager as singleton, register SitePickerDialog as Transient, set OpenSitePickerDialog factory in PermissionsView code-behind
• 60 tests passing, 3 skipped (known interactive MSAL tests)
