Answer 1

You can use

mvn test -Dgroups="com.myapp.FastTests, com.myapp.SlowTests"

But ensure that you configure properly the maven surefire plugin

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.11</version>
  <dependencies>
    <dependency>
      <groupId>org.apache.maven.surefire</groupId>
      <artifactId>surefire-junit47</artifactId>
      <version>2.12.2</version>
    </dependency>
  </dependencies>
</plugin>

See docs in: https://maven.apache.org/surefire/maven-surefire-plugin/examples/junit.html

Answer 2

Maven has since been updated and can use categories.

An example from the Surefire documentation:

<plugin>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.11</version>
      <configuration>
        <groups>com.mycompany.SlowTests</groups>
      </configuration>
</plugin>

This will run any class with the annotation @Category(com.mycompany.SlowTests.class)
