TDD

I’m really enjoying the book and am working on a toy project as I progress. But one of the things I find most disorienting is working without a test suite. I know FP makes manual testing in the Repl easier, but repeatable tests are very important too.

I know there’s not much coverage of external libraries in the book, but I think it would help immensely if there were a mention of how to write a test suite. I’ve been looking at the “fact” library¹ that’s bundled with Compojure, and while I only have brief experience with it, it looks pretty promising so far. There’s some test stuff in clojure-contrib too that might be better too; I haven’t looked at it. Regardless I think the topic deserves some coverage.

Hi Phil,

The next beta release will include unit tests for all sample code. There won’t be any prose to describe it until Beta 5, but at least you can have a look around.

Cheers,
Stuart

Phil, you may like the unit test framework for Clojure written by Shane Celis. It is a xUnit framework in the same vein as JUnit. See http://gnufoo.org/clojure/unit-test/README.html

Thanks for the info.

Stuart: are you using the library Stephen recommended, or something else?

Phil, I am using clojure.contrib.test-is, to minimize dependencies for the book.
