updating the publicqueue page and src/pages/admin test coverage to get full coverage

Overview

This MR improves test coverage for all components under src/pages/admin& public queue page , achieving 100% statement and line coverage with near-complete branch coverage.

What does this MR do and why?

This MR ensures comprehensive test coverage for:

• Admin pages (src/pages/admin)
• Public-facing queue functionality (PublicQueuePage)

Motivation:

• Eliminate untested logic paths
• Improve reliability of critical admin and queue workflows
• Strengthen confidence in UI behavior under edge cases

Approach:

• Added targeted unit tests for uncovered branches
• Covered UI states, API errors, and edge cases
• Included real-time queue scenarios (connection, reconnection, empty states)

Trade-offs:

• Some branch coverage limitations remain due to React Query internal states and optional chaining behavior

Changes Made

Test Files Updated

• tests/admin/AssignRolesPage.test.tsx (+18 tests)
• tests/admin/ManageMedicalCampsPage.test.tsx (+9 tests)
• tests/admin/ManageMedicinesPage.test.tsx (+10 tests)
• tests/pages/PublicQueuePage.test.tsx (+36 tests)

Coverage Improvements

• Achieved 100% coverage for all admin pages
• Significantly enhanced coverage for PublicQueuePage, including real-time and UI state scenarios

Technical Details

Code Quality Checklist

Code Standards

• Code follows project conventions (naming, structure, formatting)
• No console.log() or debugger statements left in code
• No unused imports, variables, or functions
• No duplicate code and use of existing components for reusability
• i18n check passed with no hardcoded strings in codebase for i18n support
• TypeScript types are properly defined (no any unless justified)
• ESLint and Prettier checks pass

  bun run lint

React Best Practices

• Components are properly split and single-responsibility
• Hooks follow rules (no conditional hooks, proper dependencies)
• State management is appropriate (local vs global state)
• No unnecessary re-renders (memoization used where needed)
• Event handlers are properly cleaned up

Component Patterns

• shadcn/ui components used correctly
• Tailwind classes follow utility-first approach
• Responsive design considered (mobile-first if applicable)
• Accessibility attributes included (aria-*, role, etc.)
• Icons from lucide-react used consistently

API & Data Fetching

• TanStack Query used for server state (if applicable)
• Loading and error states handled
• API types defined in src/types/api.ts
• Axios interceptors handle auth tokens correctly
• Use of Zod for data validations

Error Handling

• Errors are caught and handled gracefully
• User-friendly error messages displayed
• Errors are being toasted properly
• Network failures handled appropriately

Documentation

• README.md updated (if setup steps changed)
• .env.example updated (if new env vars added)
• CHANGELOG.md updated (if applicable)

Known Limitations / Technical Debt

Known Limitations / Technical Debt

• AssignRolesPage branch coverage is ~88.46% due to:
  • React Query internal state timing (isPending)
  • Optional chaining (oldUsers?.map()) not being triggerable in tests
• This is a coverage tooling limitation, not a functional gap

Additional Notes

• This is a test-only MR — no production code has been modified.
• Focus is on improving coverage, reliability, and edge-case handling across admin pages and PublicQueuePage.
• PublicQueuePage received significant test additions, especially for real-time UI states (connection, reconnection, empty states).
• Some branch coverage (AssignRolesPage ~88%) is limited by:
  • React Query internal state timing (isPending)
  • Optional chaining paths that are not realistically triggerable
• No impact on performance, runtime behavior, or API contracts.

##Notes:

• Suggested review approach:
  1. Validate edge-case coverage (null, error states, UI states)
  2. Verify test readability and maintainability
  3. Spot-check critical flows (mutations, filters, queue behavior)
