Work items powered issues list - Test coverage analysis

Summary

Based on common patterns in (project level) work items list implementations and today's bug in search/filtering, this Claude Code generated document identifies missing test cases prioritized by impact and risk.

Priority 1: Critical User-Facing Functionality (Search & Filtering Focus)

Search Functionality Tests

  1. Multiple search term combinations
    • Test: Search with "epic AND bug" should return items matching both
    • Test: Search with "feature OR enhancement" should return items matching either
    • Test: Mixed operators "epic AND (bug OR feature)"
  2. Search with special characters
    • Test: Search containing quotes "exact phrase"
    • Test: Search with wildcards epic*, *bug, *in-progress*
    • Test: Search with escape characters \[blocked\]
    • Test: Search with Unicode characters (emojis, non-Latin scripts)
  3. Search field combinations
    • Test: Title search + status filter simultaneously
    • Test: Author search + assignee filter + date range
    • Test: Label search + milestone filter + type filter
  4. Search persistence across navigation
    • Test: Search query persists when switching views
    • Test: Search state retained on browser back/forward
    • Test: Search parameters in URL are correctly applied on page load

Filtering Edge Cases

  1. Empty and null state filtering
    • Test: Filter for items with no assignee
    • Test: Filter for items with no labels
    • Test: Filter for items with no milestone
    • Test: Filter for items with empty description
  2. Date range filtering
    • Test: Created date with same start and end date
    • Test: Updated date with future dates (should show empty)
    • Test: Due date with past dates only
    • Test: Invalid date formats handling
  3. Multi-select filter behavior
    • Test: Multiple labels with AND logic
    • Test: Multiple labels with OR logic
    • Test: Multiple assignees selection
    • Test: Conflicting filter combinations (closed + in-progress)

Priority 2: Edge Cases and Input Variations

Pagination with Filters

  1. Pagination edge cases
    • Test: Apply filter that reduces results to less than one page while on page 2
    • Test: Change items per page with active filters
    • Test: Navigate to last page, then apply filter that reduces total pages
    • Test: URL manipulation with invalid page numbers

Sorting with Search

  1. Sort order preservation
    • Test: Sort by date + search term application
    • Test: Sort by priority + filter change
    • Test: Custom sort + bulk selection
    • Test: Sort direction toggle with active search

Performance and Large Data Sets

  1. Large result sets
    • Test: Search returning 1000+ results
    • Test: Filter with 100+ label options
    • Test: Scrolling performance with 500+ items
    • Test: Search debouncing with rapid typing

Input Validation

  1. Search input boundaries
    • Test: Search with 1 character
    • Test: Search with 255+ characters
    • Test: Search with only spaces
    • Test: Search with only special characters
    • Test: SQL injection attempts in search
    • Test: XSS attempts in search field

Priority 3: Error Handling Scenarios

Network and API Failures

  1. API error responses

    • Test: 500 error during search request
    • Test: 429 rate limiting during rapid searches
    • Test: Network timeout during filter application
    • Test: Partial data load failure

  2. GraphQL specific errors

    • Test: Malformed query response
    • Test: Missing required fields in response
    • Test: Type mismatch in response data
    • Test: Resolver timeout handling

State Management Errors

  1. Cache inconsistencies
    • Test: Stale cache with updated filters
    • Test: Cache invalidation on work item update
    • Test: Optimistic update rollback on error
    • Test: Concurrent filter updates from multiple tabs

User Permission Errors

  1. Access control during filtering
    • Test: Filter shows item, but user lacks view permission
    • Test: Confidential items in search results
    • Test: Permission change during active session
    • Test: Guest user filter restrictions

Priority 4: Accessibility and UX Edge Cases

Keyboard Navigation

  1. Keyboard-only operation
    • Test: Tab through all filter controls
    • Test: Enter key submits search
    • Test: Escape key clears search
    • Test: Arrow keys in dropdown filters

Screen Reader Support

  1. ARIA and announcements
    • Test: Search result count announcement
    • Test: Filter change announcements
    • Test: Loading state announcements
    • Test: Error message announcements

Specific Test Cases for Today's Bug Type

Search/Filter Synchronization Issues

  1. Filter and search state conflicts

    • Test: Clear all filters doesn't clear search
    • Test: Search doesn't reset when filters change
    • Test: Browser refresh with both search and filters
    • Test: Bookmark with complex filter+search combo

  2. URL parameter handling

    • Test: Malformed filter parameters in URL
    • Test: Duplicate parameters in URL
    • Test: Legacy parameter format compatibility
    • Test: Parameter encoding/decoding issues

  3. Real-time updates with filters

    • Test: New item created matches active filter
    • Test: Item updated no longer matches filter
    • Test: Item deleted while in filtered view
    • Test: Bulk update affecting filtered items

Recommended Test Implementation Order

  1. Immediate
    • Search with special characters
    • Search field combinations
    • Empty state filtering
    • Search input boundaries
  2. Short-term
    • Multiple search term combinations
    • Multi-select filter behavior
    • API error responses
    • Filter and search state conflicts
  3. Medium-term
    • Pagination edge cases
    • Large result sets
    • Cache inconsistencies
    • Real-time updates with filters

Test Data Requirements

Minimum test data set should include:

  • 500+ work items with varied states
  • 50+ unique labels
  • 20+ unique assignees
  • 10+ milestones
  • Items with all possible type combinations
  • Items with special characters in titles
  • Items with very long descriptions
  • Archived and deleted items
  • Confidential items
  • Items with complex hierarchies

Automation Recommendations

Critical paths for E2E tests:

  1. Search → Filter → Sort → Paginate flow
  2. Direct URL access with complex parameters
  3. Bulk operations with active filters
  4. Permission-based filtering
  5. Real-time updates with WebSocket events

Performance benchmarks:

  • Search response < 200ms for 1000 items
  • Filter application < 100ms
  • Pagination < 50ms
  • Initial page load < 2s with filters

Conclusion

The highest priority should be given to search and filtering test cases, as these are core user workflows where bugs have the most impact. Special attention should be paid to:

  1. Complex search queries with special characters
  2. Combined filter and search states
  3. Edge cases in pagination with active filters
  4. Error handling for network failures during search

These test cases will significantly improve the robustness of the work items list feature and prevent regression of search/filter bugs.
