Add Comprehensive Unit Tests for Coins List Endpoint

Description

Task

Add unit tests for coins list endpoint

Acceptance Criteria

• Endpoint returns complete list of coins by default
• Supports limit-based filtering
• Implements case-insensitive search
• Handles invalid inputs gracefully
• Preserves original data integrity

Summary of Work

Enhance test coverage for the coins list endpoint to ensure robust functionality and data integrity.

Changes Made

• Expanded unit tests for getCoinsList function
• Added more comprehensive test scenarios
• Improved test coverage for edge cases and input validation

Implementation Details

• Utilized existing test structure in src/tests/coinsList.test.js
• Verified implementation against CoinGecko API mock design
• Ensured tests cover multiple scenarios:
  1. Default coins retrieval
  2. Limit-based filtering
  3. Search-based filtering
  4. Case-insensitive search
  5. Error handling for invalid inputs

Testing Approach

• Used Vitest for test implementation
• Tested all major function behaviors
• Validated data structure and transformation
• Confirmed error handling mechanisms
• Ensured no unexpected mutations of input data

Notes

• Test suite covers primary use cases
• Easily extensible for future endpoint enhancements
• Follows existing project testing conventions

Changes Made

• Enhanced src/tests/coinsList.test.js with comprehensive test cases
• Added test for default coins retrieval
• Implemented limit-based filtering test
• Created case-insensitive search validation
• Added error handling test for invalid inputs

Tests

• Verify default coins list retrieval
• Test limit-based filtering functionality
• Validate case-insensitive search behavior
• Confirm error handling for invalid inputs
• Ensure consistent data structure
