Test cases for frontend

Swarna rathna madhuri Kanda requested to merge test-cases-for-frontend into develop

Here is your Merge Request (MR) description tailored for adding test cases for SearchUtils, Update Prescription Page, and Queue Management:

Overview

This MR adds unit test cases for SearchUtils, Update Prescription Page, and Queue Management modules. It improves overall test coverage, ensures reliability of core functionalities, and helps prevent regressions during future development.

What does this MR do and why?

This MR focuses on strengthening the testing layer of the application by introducing structured and comprehensive unit tests.

  • Motivation: These modules lacked sufficient test coverage, making it difficult to validate functionality and increasing the risk of bugs.

  • Approach:

    • Used Jest and React Testing Library for writing tests
    • Covered utility functions, UI interactions, API calls, and edge cases
    • Mocked API responses to simulate real-world scenarios

  • Trade-offs:

    • Additional time spent on writing and maintaining tests
    • Slight increase in test execution time

Changes Made

  • Added unit tests for SearchUtils functions
  • Added unit tests for Update Prescription Page (form handling, API calls)
  • Added unit tests for Queue Management component (rendering, empty states)
  • Created separate test files for each module

Technical Details

  • Root Cause: Lack of test coverage for critical modules.

  • Fix/Enhancement:

    • Implemented test cases covering:

      • Input handling
      • API success and failure scenarios
      • UI rendering and state updates

    • Used mocks for API calls and external dependencies

Type of Change

  • 🐛 Bug fix (non-breaking change that fixes an issue)
  • ✨ New feature (non-breaking change that adds functionality)
  • 💥 Breaking change (fix or feature that would cause existing functionality to change)
  • 📝 Documentation update
  • 🎨 UI/UX improvement
  • ♻️ Refactor (no functional changes)
  • ⚡ Performance improvement
  • 🧪 Test update
  • 🔧 Configuration change
  • 🚨 Security fix

Related Issues / References
