What about this one:

https://github.com/metan-ucw/ltp/commit/445e3ae253bdd11f18ec12ccc74fe99eb582eeb6

$ cat d.sh

#!/bin/sh
TST_ID="test"
TST_TESTFUNC=do_test
. tst_test.sh

do_test()
{
        tst_res TPASS "Passed"

        TST_FOO=1

        echo "$TST_PASS"
}

tst_run

# PATH is set to contain both path to tst_test.sh and d.sh
$ ./d.sh
test 1 TWARN : Reserved variable TST_FOO used!
test 1 TWARN : Reserved variable TST_PASS used!
test 1 TPASS : Passed
1

Summary:
passed   1
failed   0
skipped  0
warnings 2
