About this file
This file is trimmed to an exact byte count (10,590,414 bytes) so it can be used for boundary-value testing against an upload limit.
What boundary-value testing is
Boundary-value testing rests on the observation that defects cluster just inside, exactly at, and just outside a limit. For file size, trying only three points — just under, exactly at, and just over the cap — is enough to reveal whether a comparison uses < or <=, and whether the unit maths is based on 1000 or 1024.
The same format is offered as 9.9 / 10.0 / 10.1 MB and 24.9 / 25.0 / 25.1 MB sets. 10 MB and 25 MB are the boundaries you meet most often, as form and CMS defaults and as the Gmail attachment cap respectively.
