What have you tried?

For a fresh install, this should just be a question of supplying the 
'--allow-test-packages' option (which is directly equivalent to the 
'Test' checkbox)

The way that 'Keep'/'Best'/'Sync' choices map onto command line options 
is unfortunately complex (due to historical terribleness...), but I 
think it's something like this:

If '--force-current' option is specified, this is equivalent to 'Sync' 
(all packages will use the version from the package repository, 
downgrading if needed)

Otherwise, if '--upgrade-also' is specified, or no packages are added or 
removed by the command-line options, this is equivalent to 'Best' (use 
the 'best' available version of all packages)

Otherwise it's equivalent to 'Keep' (don't change the version of any 
already installed package).
