Sorry for the confusion. I meant "return 1" as used elsewhere in the
test suite[1].

--- >8 ---
#!/bin/sh
test_description='return 1?'
. ./test-lib.sh

test_expect_success 'return 1' '
        return 1
'

test_expect_success 'second test' '
        true
'

test_done

$ ./t9977.sh
not ok 1 - return 1
#
#         return 1
#
ok 2 - second test
# failed 1 among 2 test(s)
1..2
$
