Details:

I believe there might be a couple problems in test.m.  Here is the output of
running the test script on the "interpft.m" file:


>> [N_success, MAX_success] = test("interpft")
  ***** assert (max (abs (imag (interpft ([1:8], 20)))), 0, 2*eps);
!!!!! test failed
assert (max (abs (imag (interpft ([1:8], 20)))),0,2 * eps) expected
0
but got
   2.2542e-15
maximum absolute error 2.25417e-15 exceeds tolerance 4.44089e-16
shared variables
  scalar structure containing the fields:

    n =  11
    y =

       1.00000 + 1.00000i
       1.38397 + 1.38397i
       2.38397 + 2.38397i
       3.00000 + 3.00000i
       4.11603 + 4.11603i
       3.11603 + 3.11603i

N_success = 0
MAX_success = 0


>From the code in test.m, I believe that the test continues after a failure
only if in batch mode.  But there doesn't seem a way to control batch mode
from the option list; only by supplying an FID output argument.

However, one would think that the two output version should run all tests if
it is going to indicate now many were successful out of the total number of
tests.

Also, test.m is printing out shared variables in event of a failure.  Perhaps
there is some cruft left in the code:


      ## Show the variable context.
      if (! strcmp (__type, "error") && ! strcmp (__type, "testif")
          && ! all (__shared == " "))
        fputs (__fid, "shared variables ");
        eval (sprintf ("fdisp(__fid,bundle(%s));", __shared));
        fflush (__fid);
      endif


The shared variables that are listed are for a previous test and haven't
anything to do with the failed test, as far as I know.
