Question

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h2 mock jdbc测试。

现在运行mvn test -X时，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

它不执行任何测试（它找不到em）

这是我的pom.xml

Answer 1

你发现了两个问题第一个问题，但我会在这里记录。在Kotlin-Maven插件中，您可以将test-compile目标设置为：

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

正在编译src/main/java目录而不是src/test/java，因此您的测试根本没有编译。应该是：

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

或者，如果您的文件都在java和kotlin目录中：

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

第二个问题很可能是您尝试解决第一个问题。它在表面上看起来很好但是Surefire插件的配置不正确。 Maven Surefire插件的文档不太准确（或者它的工作原理并不完整）。如果您完全删除Surefire插件配置，它将起作用，因为默认设置已经执行了您想要的操作。或者，您可以将列出include文件模式从.kt后缀改为.class或.java后缀，即使对于Kotlin，Clojure，Scala， ...

<强>为什么呢？这是故事......

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>

不按照您的想法行事。这实际上是在Surefire中通过搜索转换并在.java上替换为.class，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扩展名，你就会破坏这种硬编码魔法。您可以在source code of Surefire plugin中看到它，用.java替换以.class结尾的文件。 Ooops，它与源文件完全无关，并且正在寻找已编译的类。

在Surefire插件2.19中，他们添加了regex and also fully qualified classname patterns的功能。所以插件决定你使用的方式似乎是文件扩展名.java。如果它看到.java它知道每个.java文件成为同名的类，那么它会查找与模式匹配的类，而不是源代码。源已经由编译器插件编译，而不是测试运行器。它没有寻找源代码的业务。

因此，此设置具有误导性，并且实际上正在使用“魔术”来找出一个类名而不仅仅是要求类名。当然，样本和一切都让你相信它与源文件有关。事实并非如此。

最好不使用配置并遵循默认命名约定。或者，如果您必须指定某些内容，请使用include配置的更现代的正则表达式或类名称版本：

        <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>

现在比较任何包中具有这些名称的任何类。

Kotlin - Maven没有执行测试
