You should be using atf_config_get.
I see that the manual page mentions atf_get but it does not describe
what it does. I am not even sure if this function should be exposed
at all. (atf_get is the counterpart of atf_set, which just returns
the value of a metadata property.)

This comment is not applicable to atf_config_get, but to prevent
confusion I'll clarify:
Keep in mind that running test programs by hand is "not supported".
The way to run test cases is by means of atf-run. If you want to
define a consistent value for a variable across test cases, you can do
so by sticking such value in the Atffile (see the prop: keyword). The
end user can always override such value by defining an override in
