Update test_upload.py

[td15]

Enhancements
Edge Case Handling:
Large File Uploads: The module now supports uploads of large files, ensuring that they are processed within server limits. Empty File Uploads: Users are prevented from uploading blank files, which could lead to errors in processing. Multiple File Uploads: The API can now handle simultaneous uploads, allowing users to upload multiple files in a single request. Security Enhancements:
Malicious File Upload Prevention: The module checks for and blocks uploads of files with potentially harmful extensions (e.g., .exe, .sh, .php). Content-Type Validation: The module verifies that the file's content matches its declared MIME type, rejecting any mismatches to prevent security vulnerabilities. SQL Injection Protection: Filenames are sanitized to prevent SQL injection attacks. Performance Optimizations:
Streaming Uploads: The module has been optimized to handle file uploads in chunks, reducing memory usage and improving performance for large files. Asynchronous Processing: Large file uploads are queued for background processing, allowing the API to remain responsive during uploads. Additional Features:
Virus Scanning: Integration with virus scanning tools (e.g., ClamAV) to scan uploaded files for malware. File Metadata Extraction: The module extracts useful metadata from uploaded files (e.g., image dimensions, PDF titles) for better management and display. Expiry Mechanism: Uploaded files can be set to automatically delete after a specified duration, helping to manage storage space. Testing
The module includes a comprehensive suite of tests to ensure its functionality and reliability. Tests cover various scenarios, including: Successful file uploads with valid content.
Handling of unsupported file types and size limits. Security checks for malicious file uploads.
