I would not be surprised if it did. Though it introduces its own
portability issues, since we cannot depend on having it. But it is
probably enough to just

  test_lazy_prereq EXPECT 'expect --version'

or something. I dunno. I have never used expect, do not have it
installed, and am not excited about introducing a new tool dependency.
But if you want to explore it, be my guest.
