This is the {{Use template sandbox testcases request}} message box and may be used to request editors to use the sandbox and testcases pages.

Note: It is normal that some of the links in the message box are red.

The template should be used as is and accepts no parameters.

The /sandbox and /testcases links are the standard names for such subpages. If those pages are created then the green /doc box for the template will detect them and link to them in its heading.
