test: added test cases for usercontributions.tsx, userprofileinfo.tsx and categories.tsx

Issue Summary

Add unit test cases for UserContributions.tsx, UserProfileInfo.tsx, and Categories.tsx to improve test coverage and ensure component reliability.

---

Problem Statement

• Test cases for these components are missing
• Leads to low test coverage and higher risk of bugs
• Developers lack confidence during changes

---

Proposed Solution

• Create test files:

  • UserContributions.test.tsx
  • UserProfileInfo.test.tsx
  • Categories.test.tsx

• Use Vitest + React Testing Library

• Cover rendering, interactions, and edge cases

---

Test-Driven Development

Acceptance Criteria (Given-When-Then)

Scenario 1: Render components

Given the components are rendered
When the UI loads
Then data should be displayed correctly

Scenario 2: User interaction

Given the components are displayed
When a user interacts
Then UI should update correctly

Test Cases

Test ID	Test Description	Precondition	Test Steps	Expected Result	Priority
TC-001	Render components	Initialized	1.Render 2.Verify UI	Data displayed	High
TC-002	Interaction test	Rendered	1.Interact 2.Verify	UI updates	High
TC-003	Edge cases	Rendered	1.Pass empty data	No crash	Medium

Unit Test Requirements

Components/Functions to Test:

Module/Component	Function/Hook	Test Cases to Cover
UserContributions.tsx	Rendering	TC-001
UserProfileInfo.tsx	Rendering	TC-001
Categories.tsx	Interaction	TC-002, TC-003

Test Assertions Required:

• Renders correctly
• Handles user interaction
• Handles errors
• Updates UI state

Implementation Details

Files to Change

File Path	Action	Purpose
src/__tests__/UserContributions.test.tsx	Create	Unit tests
src/__tests__/UserProfileInfo.test.tsx	Create	Unit tests
src/__tests__/Categories.test.tsx	Create	Unit tests

---

Technical Considerations

• Use Vitest and React Testing Library
• Mock dependencies if needed

---

UI/UX Requirements

• Correct rendering
• Proper interaction handling

---

Testing Strategy

Manual Testing

Test Environment:

• Browser: Chrome

Manual Test Steps:

1. Render components
2. Verify UI
3. Test interactions

---

Automated Testing

Unit Tests:

• Render tests
• Interaction tests
• Error handling

---

Test Data Requirements

const mockTestData = {
  user: { name: "Test" },
  categories: ["A", "B"]
}

---

Definition of Done

• Tests written and passing
• Coverage improved
• No errors
