Stress Testing with Dummy Data
When building applications that handle file uploads or storage, you often need to test how the system behaves under different conditions. Generating dummy files of precise sizes allows you to simulate these scenarios without needing real data.
Why Generate Dummy Files?
Dummy files are essential tools for Quality Assurance (QA) and development.
Testing Upload Limits
Verify that your application correctly rejects files larger than the allowed maximum (e.g., 10MB) and accepts files just under the limit.
Network Speed Tests
Check how long it takes to upload or download large files over different network connections to optimize user experience.
Storage Capacity
Fill up a disk or quota to see how the system handles 'disk full' errors or storage warnings.
How It Works
This tool runs entirely in your browser. It uses the JavaScript Blob API to create a chunk of memory filled with placeholder data (usually zeros or random bytes) of the exact size you specify. It then creates a temporary download link for that data, so you can save it to your device without using any server bandwidth.
