Test suite: testing for the *absence* of a string ?

Is it possible to use the exim test suite to test for the
*absence* of a particular string in Exim's response to EHLO,
or rather to make the test fail if a particular string occurs.

I can work around this by checking the response to HELP,
but it would be encouraging to be able to fail a test
if in a dialog like:

exim -DSERVER=server -bd -oX PORT_D
****
client -t2 127.0.0.1 PORT_D
??? 220
ehlo foobar
??? 250-
??? 250-
??? 250-
??? 250

one of the 250- responsed included the string CLIENTID,
which should not be advertised over an unecrypted connection.

Any ideas ?

If not, should I decide to implement this feature,
does anyone have thoughts on the details ?

Will not listing the right number of "250-" lines, maybe
even with their full texts, do the job?

Thanks.

Yes, that does work - as long as the lines contain
enough text to rule out the forbidden string.

I'd taken out the text from the 250- lines, since I
have had trouble with other parts of the test script,
and had forgotten that I will be able to put those
back when I have that under control.

As they say, debugging is twice as hard as writing the code,
and only on a good day am I smart enough to see whether
a test failure means the code is wrong or the test.

Thanks again.
