Draft: feat: improve test coverage for admin pages to 98%+

Suma Pullaiahgari requested to merge test/coverage-improvement into develop

Overview

This MR significantly improves test coverage for the src/pages/admin folder, achieving 98.32% statement coverage and 100% coverage for 3 out of 6 admin pages. The changes add comprehensive test suites for previously untested or under-tested components, ensuring better code quality and reducing the risk of regressions.

What does this MR do and why?

feat: improve test coverage for admin pages to 98%+

  • Added comprehensive tests for AdminDocsPage (25 tests)
  • Added comprehensive tests for CampAnalyticsPage helpers (45 tests)
  • Added tests for AssignRolesPage optimistic updates
  • Added tests for ManageMedicalCampsPage input handling
  • Added tests for ManageMedicinesPage error handling
  • Fixed eslint issues with any types
  • All 953 tests passing
  • Coverage: 98.32% statements, 89.21% branches, 97.97% functions, 99.02% lines
  • 3 pages at 100% coverage (ManageMedicinesPage, StaffAttendancePage, AdminDocsPage)

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

Branch Coverage Gaps (89.21%):

The remaining branch coverage gaps are fundamentally untestable in unit tests:

 1. CSS media queries (lg:hidden class) - JSDOM doesn't support CSS/media queries. Requires E2E tests (Cypress/Playwright).

 2. React Query optimistic update callbacks (oldUsers?.map) - Optional chaining with undefined cannot be triggered without breaking React Query's internal behavior.

 3. Cancel functions during pending mutations - Requires mocking mutation internals, which would test the mock rather than actual code.

 4. Section level conditions (h3 tags in AdminDocsPage) - The regex only parses h1-h2 tags by design.

Additional Notes

Test Strategy: - Focused on behavior testing, not implementation details - Used proper mocks for APIs and external modules (jsPDF, TanStack Query) - Covered success + failure scenarios - Covered null/undefined edge cases - Covered async logic (loading, resolved, rejected states) - Covered user interactions (click, submit, input)

Files with 100% Coverage:
 - ✅ ManageMedicinesPage.tsx (all metrics)
 - ✅ StaffAttendancePage.tsx (all metrics)
 - ✅ AdminDocsPage.tsx (statements/functions/lines)
 - ✅ AssignRolesPage.tsx (statements/functions/lines)
 - ✅ ManageMedicalCampsPage.tsx (statements/functions/lines)
