有没有一种方法可以在Maven中指定由程序包运行哪些JUnit测试

是的，您可以将surefire插件配置为仅包括某些测试

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.17</version>
        <configuration>
          <includes>
            <include>com/abc/*Test.java</include>
          </includes>
        </configuration>
      </plugin>
    </plugins>
  </build>
