Yes, we now have tests for the following cases.  It's trivial to add more
if you can think of any that might be problematic.

pws

  test -z \( || print Not zero 1
  test -z \< || print Not zero 2
  test -n \( && print Not zero 3
  test -n \) && print Not zero 4
  [ -n \> ] && print Not zero 5
  [ -n \! ] && print Not zero 6
0:test with two arguments and a token
