Test: added test cases for UI files

Issue Summary

The current codebase lacks comprehensive test coverage for UI components across the application. Several UI files are not validated through automated tests, which increases the risk of undetected bugs and inconsistencies in user interactions.

The goal of this issue is to add structured and comprehensive test cases for UI files to ensure correct rendering, interaction handling, and overall stability of the user interface.

Problem Statement

Many UI components in the application do not have associated test cases, making it difficult to verify their behavior during development and future updates. This primarily affects developers and testers, as the absence of tests reduces confidence in making changes and increases the likelihood of regressions.

The impact includes potential UI breakages, inconsistent behavior across components, and increased manual testing effort. The issue can be identified by reviewing the src/components directories, where several files lack corresponding test files in the __tests__ directory.

Proposed Solution

To address this issue, test cases will be added for all major UI components using a testing framework such as Vitest or Jest along with React Testing Library.

The approach includes:

  • Writing unit tests for UI rendering and structure
  • Testing user interactions such as clicks, inputs, and navigation
  • Mocking API calls where necessary
  • Validating loading, success, and error states

Test Cases

Test ID Test Description Precondition Test Steps Expected Result Priority
TC-001 Verify UI rendering Component available 1. Load component
2. Observe UI		 UI renders without errors High
TC-002 Test user interaction Component loaded 1. Perform click/input
2. Observe behavior		 UI responds correctly High
TC-003 Validate API data display API mocked 1. Load component
2. Inject data		 Data displayed correctly High
TC-004 Test error handling API failure 1. Load component Error message displayed Medium
TC-005 Validate loading state API pending 1. Trigger API call Loading indicator shown Medium

Test Assertions Required:

  • Renders correctly with initial state
  • Handles user input correctly
  • Validates input and shows errors
  • Calls API with correct payload
  • Handles loading state
  • Handles success response
  • Handles error response
  • Updates UI state appropriately

Implementation Details

Files to Change

File Path Action Purpose
src/components/... Modify Add testable logic if needed
src/pages/... Modify Ensure test compatibility
src/__tests__/... Create Add UI test cases

Technical Considerations

Testing will be implemented using React Testing Library to simulate real user interactions. API calls will be mocked to isolate UI behavior and ensure consistent test results. Reusable testing utilities and mock data structures will be created to improve maintainability.

UI/UX Requirements

The UI should:

  • Render consistently across components
  • Respond correctly to user actions
  • Display API data accurately
  • Handle loading and error states gracefully

Testing Strategy

Manual Testing

Test Environment:

  • Browser: Chrome
  • Viewport: Desktop and Mobile
  • User Role: General User

Manual Test Steps:

  1. Navigate to UI pages
  2. Interact with components
  3. Verify behavior and responses

Automated Testing

Unit Tests:

  • Component render tests
  • User interaction tests
  • API integration tests
  • Error handling tests

Integration Tests:

  • Multi-component interaction tests
  • Route navigation tests

Test Data Requirements 

const mockTestData = {
  user: {
    name: "Test User",
    role: "viewer"
  },
  data: [
    { id: 1, value: "Sample UI Data" }
  ]
};

Definition of Done

  • All UI components have corresponding test cases
  • Acceptance criteria satisfied
  • All test cases passing
  • High test coverage achieved (close to 100%)
  • Manual testing completed
  • No console errors
  • Code reviewed and approved
  • ESLint and formatting checks passed
