tests:add test cases to increase test coverage for src/components/ContentInput,ContributionDashboard,ContributionsList

Issue Summary

Add unit test cases to improve test coverage for ContentInput, ContributionDashboard, and ContributionsList components

Problem Statement

Currently, the frontend components located in src/components/ContentInput, ContributionDashboard, and ContributionsList do not have sufficient test coverage. The absence of unit and integration tests increases the risk of undetected bugs, reduces code reliability, and makes future refactoring unsafe.

Additionally, the lack of automated testing makes it difficult to validate component behavior such as:

User input handling

Data rendering

API interactions

Error handling

State updates

To maintain code quality and ensure stability, it is necessary to add comprehensive test cases targeting 100% test coverage for these components.

Problem Impact

Increased risk of regressions

Reduced code maintainability

Difficult debugging during feature additions

No automated validation of UI behavior

Lower overall project quality metrics

Proposed Solution

Add comprehensive unit and component test cases using a frontend testing framework such as:

Jest

React Testing Library

The tests should cover:

ContentInput component

Rendering validation

Input field change handling

Form submission behavior

Validation errors

Button click events

API call triggers (if applicable)

ContributionDashboard component

Component rendering

Data display verification

Loading state handling

Empty state handling

Error state handling

Navigation interactions

ContributionsList component

List rendering

Conditional rendering

Filtering/sorting behavior (if present)

Item click interactions

Empty list handling

Implementation Approach

1 Setup testing environment (if not configured)

npm install --save-dev jest @testing-library/react @testing-library/jest-dom

2 Create test files:

ContentInput.test.jsx ContributionDashboard.test.jsx ContributionsList.test.jsx

3 Add test scenarios:

Rendering tests

Event handling tests

State update tests

API mock tests

Edge case tests

4 Mock dependencies:

API services

Context providers

Hooks

5 Run coverage:

npm run test -- --coverage

6 Improve coverage until reaching 100%.

Acceptance Criteria

The issue will be considered complete when:

✔ Test cases exist for all three components ✔ Test coverage reaches 100% ✔ Tests pass successfully ✔ No existing functionality is broken ✔ Edge cases are covered ✔ Mocking implemented where required

Expected Outcome

Improved frontend reliability

Better maintainability

Safer refactoring

Automated validation of UI behavior

Increased project quality standards
