The Ultimate Guide to Testing File Uploads
Learn how to stress-test your storage buckets, validate mime-types, and handle edge-cases like 0-byte files.
Why File Upload Testing Matters
File uploads are a common vector for security vulnerabilities (like webshell uploads) and stability issues (like memory leaks). Testing them requires more than just uploading a single "test.jpg".
Key Test Scenarios
- Zero-byte files: Does your backend hang or crash?
- Massive files: Try uploading a 10GB file to check request timeouts.
- Mime-type spoofing: Upload a PHP script renamed as image.png.
Using FileMock
Instead of keeping a folder of "garbage files" on your desktop, use FileMock to generate these edge-cases instantly.
