测试Maven中的Clojure

Ral*_*lph 8 java maven-2 unit-testing clojure

我是Maven的新人,甚至是Clojure的新人.作为学习语言的练习,我正在写一个蜘蛛纸牌播放器程序.我还计划在Scala中编写类似的程序来比较实现(请参阅我的帖子/sf/ask/179988721/).

我已经配置了一个包含通常的src/main/clojure和src/test/clojure目录的Maven目录结构.我的pom.xml文件包含clojure-maven-plugin.当我运行"mvn test"时,它显示"没有运行测试",尽管我在src/test/clojure目录中有测试代码.当我误解了什么？这是我的pom.xml文件:

知道测试没有运行的原因吗？顺便说一句,随意建议改进Clojure代码.

你在pom.xml中遗漏的关键位(只是来自clojure-contrib pom.xml)是clojure-maven-plugin下的一个执行:

<plugin>
    <groupId>com.theoryinpractise</groupId>
    <artifactId>clojure-maven-plugin</artifactId>
