Right but then it will only be a short test:

console_record_reset();
ut_assertok(run_command("...", 0));
ut_assert_nextline()
..
ut_assert_console_end();

Then if someone expands it later they will feel obligated to add to the test.

I feel that a lot of things look too trivial to test when started, but
it is often that first trivial test that determines whether we have
tests ever. That is why we have the patman check about adding tests
for new commands.

Simon
