I do not understand this message.  "untested" means some tests were skipped.
But here no tests are skipped.

And the callee in one case already prints "untested" itself
(cd ${binlibfiledirgdb}) and in other case it just prints FAIL without any
"untested" output (runto).  In the first case there will be two "untested"
messages.

When you are so corrected with "untested" messages make sure it is printed
even in the failed "runto" case and also that "untested" is printed only once.

"untested" is inappropriate here because no tests are skipped.  Either put
also "return -1" here or remove the "untested" message.

Maybe you meant "xfail" here, that something failed in the supporting system
environment.

Likewise probably "xfail".

Likewise duplicate "untested" message.
