Lot of programmers use Python on daily basis, hardly few write tests. Writing tests can be daunting task. Tests gives lot of confidence for shipping the code. Automated tests saves lot of developer time during refactor.
This tutorial will teach audience how to write unit test, functional tests using unittest, py.test, mock and coverage library.
Objective of the tutorial is to make audience write better and useful tests. If something is hard to test, the abstraction is broken. In general testable code is good code.
Tutorial will use simple command line phonebook application which can be found here. During the course of the tutorial tests will be added to the application. These tests will be unit tests, functional tests.
The tutorial will use python standard library unittest, pytest, mock, coverage. Tutorial will not cover testing web applications with selenium.
While creating large application like web application the external service are generally mocked like database, email server etc ... Mock libraries provides set functionality to test complicated cases.
Audience should be comfortable using Command Line, virtualenv, pip and running tests from command line.
The code for the workshop will be available in https://github.com/kracekumar/UTFT . We will using Python 2.7.


Ok. I just watched Shereef's fireside chat and I was really impressed. Smart guy. I feel a thrilling sense of adventure. I really liked his restaurant v. kitchen analogy. I'm ready to roll up my sleeves and see what I can get up to. I do have a tinkering mind and I care deeply about human connection and empathy. I am feeling a bit overwhelmed by how much I need to learn in just my first few days online.
I recognized early on that it's really true, you have to take your education into you own hands at DBC. This is not something where the teacher is going to take you through everything step by step. This is a situation in which the teacher is going to challenge you and it is up to you to find a way to learn what you need using the resources available. I feel like I could do well in this environment. There are so many resources available including tutoring, peer paring, office hours, provided resources, and the whole universe Google provides.
Already I am learning so much. Even though I feel like I'm behind, I recognize that I am doing things that just a few days ago I did not know how to do. I didn't even know some of this stuff was possible. I have confidence that DBC has selected creative, kindhearted people and I look forward to working with them in person. I've already gotten to know everyone in my Accountability Group online and I found them to be very generous and extremely helpful.
I think I'm a guy who is in the category of wondering if this is going to be too much for me. Did they select the right student? Sometimes the fear can be paralyzing but then I remember to breathe and start taking steps. Small steps will work. I am hopeful that if I put in the time and effort this will be a powerfully transformative and invigorating experience for me. I have a good feeling it's going to be delicious!

13.4 Sending Mail by SMTPPyMailCgi supports two main functions (as links on the root page): composing and sending new mail to others, and viewing your incoming mail. The View function leads to pages that let users reply to, forward, and delete existing email. Since the Send function is the simplest, let's start with its pages and scripts first. 13.4.1 The Message Composition PageThe Send function steps users through two pages: one to edit a message and one to confirm delivery. When you click on the Send link on the main page, the script in Example 13-3 runs on the server. Example 13-3. PP2E\Internet\Cgi-Web\PyMailCgi\onRootSendLink.cgi#!/usr/bin/python # On 'send' click in main root window import commonhtml from externs import mailconfig commonhtml.editpage(kind='Write', headers={'From': mailconfig.myaddress}) No, this file wasn't truncated; there's not much to see in this script, because all the action has been encapsulated in the commonhtml and externs modules. All that we can tell here is that the script calls something named editpage to generate a reply, passing in something called myaddress for its "From" header. That's by design -- by hiding details in utility modules, we make top-level scripts like this much easier to read and write. There are no inputs to this script either; when run, it produces a page for composing a new message, as shown in Figure 13-3. Figure 13-3. PyMailCgi send (write) page13.4.2 Send Mail ScriptMuch like the Tkinter-based PyMailGui client program we met in Chapter 11, this page provides fields for entering common header values as well as the text of the message itself. The "From" field is prefilled with a string imported from a module called mailconfig. As we'll discuss in a moment, that module lives in another directory on the server in this system, but its contents are the same as in the PyMailGui example. When we click the Send button of the edit page, Example 13-4 runs on the server. Example 13-4. PP2E\Internet\Cgi-Web\PyMailCgi\onSendSubmit.cgi#!/usr/bin/python # On submit in edit window--finish a write, reply, or forward import cgi, smtplib, time, string, commonhtml #commonhtml.dumpstatepage(0) form = cgi.FieldStorage( ) # parse form input data # server name from module or get-style url smtpservername = commonhtml.getstandardsmtpfields(form) # parms assumed to be in form or url here from commonhtml import getfield # fetch value attributes From = getfield(form, 'From') # empty fields may not be sent To = getfield(form, 'To') Cc = getfield(form, 'Cc') Subj = getfield(form, 'Subject') text = getfield(form, 'text') # caveat: logic borrowed from PyMailGui date = time.ctime(time.time( )) Cchdr = (Cc and 'Cc: %s\n' % Cc) or '' hdrs = ('From: %s\nTo: %s\n%sDate: %s\nSubject: %s\n' % (From, To, Cchdr, date, Subj)) hdrs = hdrs + 'X-Mailer: PyMailCgi Version 1.0 (Python)\n' Ccs = (Cc and string.split(Cc, ';')) or [] # some servers reject [''] Tos = string.split(To, ';') + Ccs # cc: hdr line, and To list Tos = map(string.strip, Tos) # some addrs can have ','s try: # smtplib may raise except server = smtplib.SMTP(smtpservername) # or return failed Tos dict failed = server.sendmail(From, Tos, hdrs + text) server.quit( ) except: commonhtml.errorpage('Send mail error') else: if failed: errInfo = 'Send mail error\nFailed recipients:\n' + str(failed) commonhtml.errorpage(errInfo) else: commonhtml.confirmationpage('Send mail') This script gets mail header and text input information from the edit page's form (or from parameters in an explicit URL), and sends the message off using Python's standard smtplib module. We studied smtplib in depth in Chapter 11, so I won't say much more about it now. In fact, the send mail code here looks much like that in PyMailGui (despite what I've told you about code reuse; this code would be better made a utility). A utility in commonhtml ultimately fetches the name of the SMTP server to receive the message from either the mailconfig module or the script's inputs (in a form field or URL parameter). If all goes well, we're presented with a generated confirmation page, as in Figure 13-4. Figure 13-4. PyMailCgi send confirmation pageNotice that there are no usernames or passwords to be found here; as we saw in Chapter 11, SMTP requires only a server that listens on the SMTP port, not a user account or password. As we also saw in that chapter, SMTP send operations that fail either raise a Python exception (e.g., if the server host can't be reached) or return a dictionary of failed recipients. If there is a problem during mail delivery, we get an error page like the one shown in Figure 13-5. This page reflects a failed recipient -- the else clause of the try statement we used to wrap the send operation. On an actual exception, the Python error message and extra details would be displayed. Figure 13-5. PyMailCgi send error pageBefore we move on, you should know that this send mail script is also used to deliver reply and forward messages for incoming POP mail. The user interface for those operations is slightly different than for composing new email from scratch, but as in PyMailGui, the submission handler logic is the same code -- they are really just mail send operations. It's also worth pointing out that the commonhtml module encapsulates the generation of both the confirmation and error pages, so that all such pages look the same in PyMailCgi no matter where and when they are produced. Logic that generates the mail edit page in commonhtml is reused by the reply and forward actions too (but with different mail headers). In fact, commonhtml makes all pages look similar -- it also provides common page header (top) and footer (bottom) generation functions, which are used everywhere in the system. You may have already noticed that all the pages so far follow the same pattern: they start with a title and horizontal rule, have something unique in the middle, and end with another rule, followed by a Python icon and link at the bottom. This common look-and-feel is the product of commonhtml; it generates everything but the middle section for every page in the system (except the root page, a static HTML file). If you are interested in seeing how this encapsulated logic works right now, flip ahead to Example 13-14. We'll explore its code after we study the rest of the mail site's pages. <IP_ADDRESS> Using the send mail script outside a browserI initially wrote the send script to be used only within PyMailCgi, using values typed into the mail edit form. But as we've seen, inputs can be sent in either form fields or URL parameters; because the send mail script checks for inputs in CGI inputs before importing from the mailconfig module, it's also possible to call this script outside the edit page to send email. For instance, explicitly typing a URL of this nature into your browser (but all on one line and with no intervening spaces): http://starship.python.net/~lutz/ PyMailCgi/onSendSubmit.cgi?site=smtp.rmi.net&<EMAIL_ADDRESS><EMAIL_ADDRESS>Subject=test+url& text=Hello+Mark;this+is+Mark will indeed send an email message as specified by the input parameters at the end. That URL string is a lot to type into a browser's address field, of course, but might be useful if generated automatically by another script. As we saw in Chapter 11, module urllib can then be used to submit such a URL string to the server from within a Python program. Example 13-5 shows one way to do it. Example 13-5. PP2E\Internet\Cgi-Web\PyMailCgi\sendurl.py#################################################################### # Send email by building a URL like this from inputs: # http://starship.python.net/~lutz/ # PyMailCgi/onSendSubmit.cgi?site=smtp.rmi.net& #<EMAIL_ADDRESS>#<EMAIL_ADDRESS># Subject=test+url& # text=Hello+Mark;this+is+Mark #################################################################### from urllib import quote_plus, urlopen url = 'http://starship.python.net/~lutz/PyMailCgi/onSendSubmit.cgi' url = url + '?site=%s' % quote_plus(raw_input('Site>')) url = url + '&From=%s' % quote_plus(raw_input('From>')) url = url + '&To=%s' % quote_plus(raw_input('To >')) url = url + '&Subject=%s' % quote_plus(raw_input('Subj>')) url = url + '&text=%s' % quote_plus(raw_input('text>')) # or input loop print 'Reply html:' print urlopen(url).read( ) # confirmation or error page html Running this script from the system command line is yet another way to send an email message -- this time, by contacting our CGI script on a remote server machine to do all the work. Script sendurl.py runs on any machine with Python and sockets, lets us input mail parameters interactively, and invokes another Python script that lives on a remote machine. It prints HTML returned by our CGI script: C:\...\PP2E\Internet\Cgi-Web\PyMailCgi>python sendurl.py Site>smtp.rmi.net<EMAIL_ADDRESS>To<EMAIL_ADDRESS>Subj>test sendurl.py text>But sir, it's only wafer-thin... Reply html: <title>PyMailCgi: Confirmation page (PP2E)</title>
PyMailCgi Confirmation

Send mail operation was successful

Press the link below to return to the main page.

  Back to root page  The HTML reply printed by this script would normally be rendered into a new web page if caught by a browser. Such cryptic output might be less than ideal, but you could easily search the reply string for its components to determine the result (e.g., using string.find to look for "successful"), parse out its components with Python's standard htmllib module, and so on. The resulting mail message -- viewed, for variety, with Chapter 11's PyMailGui program -- shows up in my account as seen in Figure 13-6. Figure 13-6. sendurl.py resultOf course, there are other, less remote ways to send email from a client machine. For instance, the Python smtplib module itself depends only upon the client and POP server connections being operational, whereas this script also depends on the CGI server machine (requests go from client to CGI server to POP server and back). Because our CGI script supports general URLs, though, it can do more than a "mailto:" HTML tag, and can be invoked with urllib outside the context of a running web browser. For instance, scripts like sendurl.py can be used to invoke and test server-side programs. |

The Mid Sussex Tri Club was formed in 2000, it started with an amalgamation of two clubs that became 'the Mid Sussex tri club'. Amongst those original members we still have the famous five and they are still very much the heart of the club. Ten years on and their knowledge and experience spreads across the club. They are a very professional, committed, inspiring and friendly bunch! The club has grown to over 100 members today and still has a great atmosphere.
We train pretty hard and enjoy the benefits of the all the training in the glory of competing and completing many local races we cater for all abilities from not having done a triathlon to multiple Ironmen.
