"Refactoring Legacy Code" talk: Tuesday, Feb 28, 7PM, Commons Lil' Tex
Sukant Hajra
It's extremely rare that I'd suggest that a student attend a Java Users Group.
JUGs often cover crusty, boring, and bloated technologies (like Java).
But this speaker is one I'm interesting is hearing out. I've seen his writing
in a few places now (his blog and a chapter in Clean Code), and I think he'll
focus a lot less on a specific technology, and much more on the larger
problem of working with complicated code in a team environment.
This is a /huge/ problem, and definitely one that motivates me to work with
students. I'm thinking if we can attend this talk, maybe at the next meetup,
we can discuss it the topic more. All of the writeup for this event looks like
really good stuff to expose students to (and something they have almost no
experience with).
By the way, I believe our next meetup is next Monday, the day /before/ this
event. I'll confirm that and either Lane or I will send out a meeting notice.

Subject: [AustinJUG] Meeting Announcement: Refactoring Legacy Code with JMockIt - Tuesday February 28th, 2012, 7-9 PM, Commons Lil' Tex
Hi AustinJUGenites,
Next week we have a presentation by Brett Schuchert, a Principal Consultant at
ThoughtWorks with 20+ years of teaching experience, who will give a highly
interactive and code-centric talk on refactoring legacy code with JMockIt.
Smart refactoring techniques should be part of every seasoned developer's
toolbox.
ThoughtWorks (http://www.thoughtworks.com) is also graciously providing lots of
free pizza before the meeting starting at 6:30 PM!
Hope to see you next week!
Rob

Title: Refactoring Legacy Code with JMockIt
Speaker: Brett Schuchert
Presentation Abstract
---------------------
In "Working Effectively with Legacy Code" (Welc hereafter), Michael Feathers
defines legacy code as code without automated tests - I like to add to that
definition "that someone depends upon, e.g., in production".
Legacy Code is hard to work with? Or is it? Modern mocking tools make creating
what Michael Feathers calls a "link seam" easy, language-driven rather than
build driven, fast, reliable, and, frankly, cool as hell. I like to call this a
"dynamic link seam" instead of a boring old link seam. The former is cool,
fast, automated, and built into the language (or a library), while the latter
requires custom build scripts, custom build targets, and may, depending on the
language, multiple executables.
We'll take a look at some legacy code and use a modern mocking tool, JMockit to
write some tests to exercise the production code. We will then do some quick
Welc-based refactorings on the code to see:
* How to do it
* Does it improve the code
* Do the tests age well
* What happens if we were to use the modern mocking tool on the "after" code
* Does this suggest anything about having all that power at your fingertips?
This is a code-intensive discussion.
