There's a line in the Writing R Extensions manual section 2.5
Cross-refernces for R-devel that says:
"Packages referred to by these ‘other forms’ should be declared in the
DESCRIPTION file, in the ‘Depends’, ‘Imports’, ‘Suggests’ or ‘Enhances’
The other forms are the forms of links to other packages. So presumably
you don't mention those packages in your DESCRIPTION file. Generally
that means they should be listed in Suggests, which doesn't force them
to be installed, but they will be installed during tests. You might
also argue they should be in Enhances, though that seems a worse fit.
