Where 5 KB matters

A 5,120-byte file: larger than a cookie, smaller than a typical HTTP header limit. These are the default limits a file of this size is useful for testing:

SystemLimitNote
Browser cookies4,096 bytes per cookie5 KB does not fit in one cookie.
Vite asset inlining4 KB by default (assetsInlineLimit)A 5 KB asset is emitted as a separate file rather than inlined as base64.
nginx and Apache request headers8 KB per header line by default5 KB fits; the 10 KB sample does not.

All 5 KB sample files

Use this file for

  • Smoke tests in CI that must run in milliseconds
  • Testing configuration loaders and linters
  • Checking CI pipeline tooling

Testing notes for YAML

  • Unquoted values are typed by guesswork. In YAML 1.1 parsers the country code NO becomes false, and a version such as 1.10 becomes the number 1.1.
  • Loading untrusted YAML with a full loader can construct arbitrary objects in some libraries; always use the safe loader.
