Where 3 MB matters

A 3,145,728-byte file, 3 MB in the binary units that operating systems and upload limits use. It is useful wherever a form, an API gateway, a storage quota or a mail server is configured with a limit of about this size.

  • Finding the first upload limit in a new stack
  • Testing import features that accept more than one delimiter
  • Checking delimiter detection

Testing notes for TSV

  • Windows does not open .tsv in Excel by default, so users rename files to .txt or .csv, and the extension stops describing the content.
  • A field cannot contain a tab or a line break. Exporters deal with that in incompatible ways: some write backslash escapes such as \t, some apply CSV-style quotation marks, and some corrupt the row.
