test_terminal: ensure redirections work reliably
For terminal tests that capture output/stderr, the TTY prerequisite
warning does not quite work for commands like
test_terminal foo >out 2>err
because the warning gets "swallowed" up by the redirection that's
supposed only to be done by the subcommand.
Even worse, the outcome depends on whether stdout was already a
terminal (in which case test_terminal is a noop) or not (in which case
test_terminal introduces a pseudo-tty in the middle of the pipeline).
$ test_terminal.perl sh -c 'test -t 1 && echo >&2 YES' >out
YES
$ sh -c 'test -t 1 && echo >&2 YES' >out
$
So:
- use the test_terminal script even when running with "-v".
- skip tests that require a terminal when the test_terminal
script is unusable because IO::Pty is not installed.
- write the "need to declare TTY prerequisite" message to fd 4,
where it will be printed when running tests with -v, rather
than being swallowed up by an unrelated redireciton.
