I am new at Maven and even newer at Clojure. As an exercise to learn the language, I am writing a spider solitaire player program. I also plan on writing a similar program in Scala to compare the implementations (see my post <https://stackoverflow.com/questions/2571267/modern-java-alternatives-closed>).

I have configured a Maven directory structure containing the usual src/main/clojure and src/test/clojure directories. My pom.xml file includes the clojure-maven-plugin. When I run "mvn test", it displays "No tests to run", despite my having test code in the src/test/clojure directory. As I misnaming something? Here is my pom.xml file:

Here is my Clojure source file (src/main/clojure/org/dogdaze/spider\_player/Deck.clj):

Any idea why the test is not running? BTW, feel free to suggest improvements to the Clojure code.
