I wrote a few comments around the testing process here (referring to your blog post): http://erlingwl.wordpress.com/2010/03/07/testing-clojure/ Cheers, Erling Hi Sam,

In any case the screencast doesn't actually demonstrate TDD, but I'm sure you knew that :-) Hi Martin,

You can just escape the T like.. {{ someDate|date:'Ymd\TGi' }} I know it’s a little late, but I came across this page searching for Template date filtering in Django and thought I would help others that are searching the same..

I've just recently experienced a totally different level of "struggle" with TDD in clojure. In looking for information on TDD in clojure, i found http://nakkaya.com/2009/11/18/unit-testing-in-clojure/. As i tried to go through the examples of using clojure.test in clojure-test-mode in emacs, i kept getting an error message about an unmatched parenthesis. It turns out you must operating in a namepace other than the default, ie (ns foo.tdd (:use clojure.test)). Spent a long agonising night banging my head against the keyboard... That said, small unit tests for blackbox testing seems very straightforward in clojure. And really that's what you need most. Clojure.test reminds me a lot of "e.g." in Tcl, which i absolutely love. Just send in data, test against expected return data. I think experience with bulky, complicated unit-testing frameworks obscures the simplicity of blackbox testing in general. Hi.

Don't have answers yet, but one thing you should try is REPL more often. I have set up Slime on my emacs that lets me eval regions/buffers etc. This way there is a quick feedback about what i intend to achieve. The problem is, this doesn't result in a bunch of tests for my automated tests, whereas TDD would have resulted in it. I am still going through the same problem.

Due to the majority of your code bring pure functions, testing it is as simple as passing in sample data and validating the output. The hard part for me was working out when to use the repl, and when to write a test. My current rule is that I use the repl for figuring out implimentation, wheras tests drive the API of your functions. You might be interested in watching my katacast, where I do full tdd in clojure.
