You can use:

inherit
    KL_ShARED_OPERATING_SYSTEM

    if operating_system.is_windows then ...
    if operating_system.is_unix then ...

In fact I do something like that in ET_TEST_AST_PRINTER
(in $GOBO/test/tools). getest can be given the following variable:

    getest -Dfull_test  ...

and then in ET_TEST_AST_PRINTER you can find:

    a_full_test :=  variables.has ("full_test")

In order for geant to pass the variable "full_test" to getest,
I had to change $GOBO/misc/test.eant and add:

    <define name="full_test" value="true" if="${full_test}"/>

in the <getest> task of the "test" target. You could do the same
with the variable "device" and values such as "COM1". However,
having to edit $GOBO/misc/test.eant is not very nice. I don't
know how we can try to avoid that.

Not currently.

getest does not traverse the ancestor classes to find test routines.
I wrote a tool at work, based on the code of getest, which does
that (and even more), but getest is pretty rudimentary.
