It is the right way to do and avoid to get test related JAR into your classpath

If your are upgrading from RESThub <= 1.1.2.x, you should have to add the following lines to your pom.xml :

       <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>test-jetty-servlet</artifactId>
            <scope>test</scope>
        </dependency>
