This may be true, but most tests do not really need an out file and better be
verified by asserting. There are some python tests that have pointless out
file with the output of python unittest:

$ cat tests/qemu-iotests/tests/nbd-multiconn.out
...
--
Ran 3 tests

OK

This is not only unhelpful (update the output when adding a 4th test)
but fragile.
if unitests changes the output, maybe adding info about skipped tests, or
changing "---" to "", the test will break.

But for now I agree the test framework should keep the current behavior.

This means that you cannot add a test without a *.out* file, which may
  be useful when you don't use the out file for validation, but we can
add this later if needed.


I don’t think tests work without a reference output, do they?  At least 
a couple of years ago, the ./check script would refuse to run tests 
without a corresponding .out file.

This means that you cannot add a test without a *.out* file, which may
 be useful when you don't use the out file for validation, but we can
add this later if needed.

I'll change the code to check both conditions.
