Looks like a good idea. A couple of thoughts:

- I think the tests should be written in the style of
$node->command_fails instead of just command_fails. At least, that's
how it's done in the pg_basebackup tests.

- I think the tests will fail if libz support is not built. Again,
pg_basebackup doesn't have tests for that. So maybe omit that and
address it later.

- The variable exit_on_stop seems redundant with time_to_abort. They do
the same thing, so maybe your patch could reuse it.
