Kotlin - Maven未执行测试

Question

所以我有一个我想测试的Kotlin应用程序。我的测试（.kt）文件在Eclipse中成功执行。 （测试本身是一个h2 mock jdbc测试）。

现在运行mvn test -X当它说：

releases: [enabled => true, update => never] 
] 
[DEBUG] (s) reportFormat = brief 
[DEBUG] (s) reportsDirectory = C:\Users\Ivar\workspace\anotherworkspace\newrestservice\complete\target\surefire-reports 
[DEBUG] (f) rerunFailingTestsCount = 0 
[DEBUG] (f) reuseForks = true 
[DEBUG] (s) runOrder = filesystem 
[DEBUG] (f) shutdown = testset 
[DEBUG] (s) skip = false 
[DEBUG] (f) skipAfterFailureCount = 0 
[DEBUG] (s) skipTests = false 
[DEBUG] (s) suiteXmlFiles = [] 
[DEBUG] (s) testClassesDirectory = C:\Users\Ivar\workspace\anotherworkspace\newrestservice\complete\target\test-classes 
[DEBUG] (s) testFailureIgnore = false 
[DEBUG] (s) testNGArtifactName = org.testng:testng 
[DEBUG] (s) testSourceDirectory = C:\Users\Ivar\workspace\anotherworkspace\newrestservice\complete\src\test\java 
[DEBUG] (s) threadCountClasses = 0 
[DEBUG] (s) threadCountMethods = 0 
[DEBUG] (s) threadCountSuites = 0 
[DEBUG] (s) trimStackTrace = true 
[DEBUG] (s) useFile = true 
[DEBUG] (s) useManifestOnlyJar = true 
[DEBUG] (s) useSystemClassLoader = true 
[DEBUG] (s) useUnlimitedThreads = false 
[DEBUG] (s) workingDirectory = C:\Users\Ivar\workspace\anotherworkspace\newrestservice\complete 
[DEBUG] (s) project = MavenProject: org.springframework:gs-rest-service:0.1.0 @ C:\Users\Ivar\workspace\anotherworkspace\newrestservice\complete\pom.xml 

而且它不执行任何测试（它无法找到EM）

这里是我的pom.xml

Answer 1

两个问题，第一个问题你发现自己，但我会在这里记录。在科特林，Maven插件你有test-compile目标为设置：

<execution> 
     <id>test-compile</id> 
     <goals> 
      <goal>test-compile</goal> 
     </goals> 
     <configuration> 
      <sourceDirs> 
       <sourceDir>${project.basedir}/src/main/java</sourceDir> 
      </sourceDirs> 
     </configuration> 
</execution> 

这是编译的，而不是src/test/java的src/main/java目录，以便您的测试并不是在所有的编译。应该是：

  <sourceDirs> 
       <sourceDir>${project.basedir}/src/test/java</sourceDir> 
      </sourceDirs> 

或者，如果你的文件都在java和kotlin目录：

  <sourceDirs> 
       <sourceDir>${project.basedir}/src/test/java</sourceDir> 
       <sourceDir>${project.basedir}/src/test/kotlin</sourceDir> 
      </sourceDirs> 

第二个问题可能你试图解决的第一个。它看起来很好，但是Surefire插件的配置不正确。 Maven Surefire插件的文档不太准确（或者它不完整）。如果你完全删除了Surefire插件配置，它将会工作，因为默认设置已经做到了你想要的。或者你也可以从具有.kt后缀改为.class或.java后缀以及那些将罚款甚至科特林，Clojure中，斯卡拉，列出include文件模式的改变...

为什么？这里是故事...

此配置：

 <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-surefire-plugin</artifactId> 
      <version>2.19.1</version> 
      <configuration> 
       <includes> 
        <include>**/Test*.java</include> 
        <include>**/*Test.java</include> 
        <include>**/*TestCase.java</include> 
        <include>**/RandomName.java</include> 
       </includes> 
      </configuration> 
     </plugin> 

没有做什么，你认为它。这实际上是在神火做一个搜索和替换.java到.class转化，并在内部变为：

  <configuration> 
       <includes> 
        <include>**/Test*.class</include> 
        <include>**/*Test.class</include> 
        <include>**/*TestCase.class</include> 
        <include>**/RandomName.class</include> 
       </includes> 
      </configuration> 

但是如果你使用.kt扩展你打破这个硬编码的魔力。您可以在source code of Surefire plugin中看到它，它将替换以.java结尾的文件和.class。 Ooops，它根本与源文件无关，并且正在寻找编译类。

在Surefire插件2.19他们增加了能力regex and also fully qualified classname patterns。所以插件决定你使用的方式似乎是由文件扩展名.java。如果它看到.java它知道每个.java文件都变成了一个具有相同名称的类，所以它会查找与模式匹配的类，而不是源代码。源代码已经由编译器插件编译，而不是测试运行器。它没有业务寻找源代码。

所以这个设置是误导性的，真的是用“魔术”来找出一个类名，而不是只是要求输入类名。当然，样本和一切完全让你相信它与源文件有关。事实并非如此。

最好不要使用配置，并遵循默认的命名约定。或者，如果你必须指定的东西，用更现代的正则表达式或类名称版本的include配置：

 <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-surefire-plugin</artifactId> 
      <version>2.19.1</version> 
      <configuration> 
       <includes> 
        <include>Test*</include> 
        <include>*Test</include> 
        <include>*TestCase</include> 
        <include>RandomName</include> 
       </includes> 
      </configuration> 
     </plugin> 

这是现在比较任一类别与任何包的名称。
