Where 1 KB matters
The smallest practical test file: 1,024 bytes, small enough to travel in a single network packet. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Ethernet | 1,500 bytes (typical MTU) | A 1 KB payload fits in one packet with its headers. |
| Browser cookies | 4,096 bytes per cookie | 1 KB is well inside the limit; the 5 KB sample is over it. |
Use this file for
- Smoke tests in CI that must run in milliseconds
- Testing data import features
- Checking delimiter and encoding detection
Testing notes for CSV
- Splitting each line on commas breaks on quoted fields. Test with the quoted-fields sample before trusting an importer.
- Excel opens CSV files using the system locale, so a file that works in one country shows everything in one column in another.
