Self-Test Script

The last file in the mailtools package, Example 13-26, lists the self-test code for the
package. This code is a separate script file, in order to allow for import search path
manipulation—it emulates a real client, which is assumed to have a mailconfig.py
module in its own source directory (this module can vary per client).

Example 13-26. PP4E\Internet\Email\mailtools\selftest.py

mailconfig normally comes from the client's source directory or

sys.path; for testing, get it from Email directory one level up

import sys
sys.path.append('..')
import mailconfig
print('config:', mailconfig.file)

get these from init

from mailtools import (MailFetcherConsole,
MailSender, MailSenderAuthConsole,
MailParser)

if not mailconfig.smtpuser:
sender = MailSender(tracesize=5000)
else:
sender = MailSenderAuthConsole(tracesize=5000)

sender.sendMessage(From = mailconfig.myaddress,
To = [mailconfig.myaddress],
Subj = 'testing mailtools package',
extrahdrs = [('X-Mailer', 'mailtools')],
bodytext = 'Here is my source code\n',
attaches = ['selftest.py'],
)

bodytextEncoding='utf-8', # other tests to try

attachesEncodings=['latin-1'], # inspect text headers

attaches=['monkeys.jpg']) # verify Base64 encoded

to='i18n adddr list...', # test mime/unicode headers

change mailconfig to test fetchlimit

fetcher = MailFetcherConsole()
def status(*args): print(args)

hdrs, sizes, loadedall = fetcher.downloadAllHeaders(status)
for num, hdr in enumerate(hdrs[:5]):
print(hdr)
