Remember - knowing how to find out an answer is more important than
memorizing the answer.  Learn to fish!  RTFM!  (Read The Fine Manual)

Keep up on your readings (Course Outline: average 4 hours/week homework)

In the labs this week (Week 10) your task was to demonstrate that you
could run the automated test script to test the smtpclient.pl script.
(The script had to have its argument parsing implemented, which was your
task last week.)

Automated Testing - use it right from the start
-----------------

I've provided a script that will do automated testing of your SMTP client,
and I've written a few simple automated tests.  You must use this script
to test your SMTP client, and you must add your own tests to the script
to test things that I haven't.

Don't be limited by the categories or tests I've coded in the script -
my list of tests is very incomplete.  Rewrite the test suite to suit
yourself.  Add more tests to the suite and organize the tests that are
there into logical categories.

You must understand, by reading RFC2821, the responses (or categories of
responses) that an SMTP server might issue when you write your test cases.

Test that your client can handle the valid types of responses that an SMTP
server might issue.  A minimally functioning client must examine the SMTP
server response code as documented in RFC 2821 Section 4.2, 4.2.1, 4.3.2:

Q:  T/F SMTP clients can figure out how to proceed based on just the
    first digit of an SMTP reply code; they can usually ignore the
    rest.  (RFC 2821 Section 4.2, 4.2.1, 4.3.2)

If you start immediately using the automated testing script to test your
client, you'll save time over doing manual testing and then having to
repeat all your tests for the test suite README.txt file.

Some forms of programming have you write the test suite first, then
write the code to pass all the tests.
