Hi,
I wonder what kind of interest there is on Test Driven Development (TDD)
in R.
Test Driven Development consists of writing the test before the
function, and iteratively build the function until it passes the test.
Python and Ruby (specially Ruby) have very strong test-oriented
cultures. In fact, in Ruby at least the custom is to do TDD and lately
Behavior-driven development (BDD). In BDD, one writes a story of what
one would want the code to do. This story is almost native English, and
then the test suite converts it into something that the language
understand as tests.
There are some posts on the list about this, but they are about testing
in general (Runit), not TDD. Example:
http://thread.gmane.org/gmane.comp.lang.r.general/85047
Recently, I found there is an alpha, but working implementation of TDD
for Komodo edit:
www.sciviews.org/SciViews-K/index.html
The editor has a green bar that becomes red as soon as one edits a
function, and that edit breaks the tests. This is tremendously useful.
Using Gmane search, the only mention I could find on svUnit was:
http://thread.gmane.org/gmane.comp.lang.r.general/136632/focus=136662
I think this could make a great UseR 2009 talk. Ideally, by someone with
more R experience than me, and even more ideally by Philippe Grosjean
:), but it push comes to shove, I could prepare such a talk.
Would this be interesting at all? Are there any resources that I have
missed?
There is the RUnit package which is a mature xUnit implementation for R.
I don't know of a tight integration into an editor (apart from
that it is _planned_ for StatET, the Eclipse R plug-in), but
as such it is very useful already.
