This PR addresses a testing gap in the IPFS utility functions by adding comprehensive unit tests for
getContentTypeFromExtensionanddetectContentType.🎯 What: The testing gap for IPFS content type detection utilities has been addressed.
📊 Coverage:
getContentTypeFromExtension: Verified correct MIME type mapping for common extensions, case-insensitive handling, filenames with multiple dots, hidden files (leading dots), files with no extensions, trailing dots, and full file paths.detectContentType: Verified magic byte detection for PNG, JPEG, GIF, and PDF. Also verified content-based detection for HTML (tags) and JSON (parsing).✨ Result: Improved reliability and confidence in the IPFS utility layer. Any future changes to these mapping or detection logic will now be caught by these automated tests.
