But 't/README' sayeth:
Don't:
- exit() within a <script> part.
And it's right: 'exit' terminates the shell process it's invoked in,
i.e. the whole test script (well, unless it's invoked in a subshell)
without executing the remaining tests and the usual housekeeping and
reporting.
Consider the following test script:
-- >8 --
#!/bin/sh
test_description='exit 1?'
. ./test-lib.sh
test_expect_success 'exit 1' '
exit 1
'
test_expect_success 'second test' '
true
'
test_done
-- >8 --
It's output:
$ ./t9999-exit.sh
FATAL: Unexpected exit with code 1
$ sed -e 's/exit 1/false/' -i t9999-exit.sh
$ ./t9999-exit.sh not ok 1 - false
#
# false
#
ok 2 - second test
# failed 1 among 2 test(s)
1..2
