It seems to work for me, so I'm not sure how to debug the problem.

The test suite used to be in expect (DejaGNU) but it was somewhat harder 
to write tests than it is now.  And, as I remember it, slower to run the 
tests, because each one started a new Octave process.  Maybe those 
problems could be avoided by automatically generating the tests for 
expect from the current tests we have and using some other method of 
running them with expect that what we were using.  But as you imply, it 
would take some time to make that work...
