Surely it's already documented that variants you specify are passed down to any dependencies that get built (but not to any that don't need to be built)? But maybe it is worth mentioning that for mpkg, all packages get rebuilt, so the specified variants are applied to all of the ports, even those that were already installed (if that's not already mentioned in the guide).

What does that mean?

MacPorts ports always install header files where possible. Many ports also install examples or documentation. If these files are unwanted in your package, you may need to manually edit the package after it's been made.
As for test files, if you mean tests that get run by the `port test` command, then I would not expect those to be installed by a port; they would be used at test time and would not be needed afterwards.
