让ScalaTest从maven.运行我的测试

Question

我直接从the documentation把这个添加到我的pom.xml中

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.7</version>
    <configuration>
      <skipTests>true</skipTests>
    </configuration>
  </plugin>
  <plugin>
    <groupId>org.scalatest</groupId>
    <artifactId>scalatest-maven-plugin</artifactId>
    <version>1.0</version>
    <configuration>
      <reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory>
      <junitxml>.</junitxml>
      <filereports>TestSuite.txt</filereports>
    </configuration>
    <executions>
      <execution>
        <id>test</id>
        <goals>
          <goal>test</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

运行mvn test会给我带来：

Discovery starting.
Discovery completed in 265 milliseconds.
Run starting. Expected test count is: 0
DiscoverySuite:
Run completed in 283 milliseconds.
Total number of tests run: 0
Suites: completed 1, aborted 0
Tests: succeeded 0, failed 0, canceled 0, ignored 0, pending 0
No tests were executed.

但是，在src/test/scala下有几个测试应该已经被发现并运行。

我甚至尝试过运行mvn test-compile compile，只是想看看是否出现了什么。结果不出所料：

[INFO] Nothing to compile - all classes are up to date

那么，为什么它们没有被发现呢？我的文件都被命名为*Test.scala，并且像在scalatest documentation中那样编写。

在我当前的项目中，我们在pom.xml中有以下配置：

 <plugin>
    <groupId>net.alchim31.maven</groupId>
    <artifactId>scala-maven-plugin</artifactId>
    <version>3.2.2</version>
    <executions>
      <execution>
        <id>compile</id>
        <goals>
          <goal>compile</goal>
        </goals>
        <phase>compile</phase>
      </execution>
      <execution>
        <id>test-compile</id>
        <goals>
          <goal>testCompile</goal>
        </goals>
        <phase>test-compile</phase>
      </execution>
      <execution>
        <phase>process-resources</phase>
        <goals>
          <goal>compile</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

  <plugin>
    <groupId>org.scalatest</groupId>
    <artifactId>scalatest-maven-plugin</artifactId>
    <version>1.0</version>
    <configuration>
      <reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory>
      <stdout>W</stdout>
    </configuration>
    <executions>
      <execution>
        <id>scala-test</id>
        <goals>
          <goal>test</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

由于很容易猜测，第一个插件负责编译和资源处理，而第二个插件只在测试目标期间运行它们。
