How to run Junit TestSuites from gradle?

Question

I am trying to migrate from Ant build to Gradle in my project. There are a bunch of test cases (subclasses of junit.framework.TestCase) and few test suites (subclasses of junit.framework.TestSuite). Gradle automatically picked up all test cases(subclasses of junit.framework.TestCase) to be run, but not the suites (subclasses of junit.framework.TestSuite).

I probably could work around by calling ant.junit to run it. But, I feel there should be a native easy way to force gradle to pick them and run. I couldn't find anything in the document . Am I missing something?

This was hard for me to figure out, but here is an example:

// excerpt from https://github.com/djangofan/WebDriverHandlingMultipleWindows
package webdriver.test;
import http.server.SiteServer;
import java.io.File;
import java.io.IOException;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
@Suite.SuiteClasses({ TestHandleCacheOne.class, TestHandleCacheThree.class, TestHandleCacheThree.class })
public class SuiteOne extends MultiWindowUtils {

    public static SiteServer fs;

    @BeforeClass
    public static void setUpSuiteOne() {
        File httpRoot = new File("build/resources/test");
        System.out.println("Server root directory is: " + httpRoot.getAbsolutePath() );
        int httpPort = Integer.parseInt("8080");
        try {
            fs = new SiteServer( httpPort , httpRoot );
        } catch (IOException e) {
            e.printStackTrace();
        }
        initializeBrowser( "firefox" );
        System.out.println("Finished setUpSuiteOne");
    }

    @AfterClass
    public static void tearDownSuiteOne() {
        closeAllBrowserWindows();  
        System.out.println("Finished tearDownSuiteOne");
    }

}

And a build.gradle similar to this:

apply plugin: 'java'
apply plugin: 'eclipse'
group = 'test.multiwindow'

ext {
    projTitle = 'Test MultiWindow'
    projVersion = '1.0'
}

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '2.+'
    compile group: 'junit', name: 'junit', version: '4.+'
    compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.+'
}

task testGroupOne(type: Test) {
   //include '**/*SuiteOne.*'
   include '**/SuiteOne.class'
   reports.junitXml.destination = "$buildDir/test-results/SuiteOne")
   reports.html.destination = "$buildDir/test-results/SuiteOne")
}

task testGroupTwo(type: Test) {
   //include '**/*SuiteTwo.*'
   include '**/SuiteTwo.class'
   reports.junitXml.destination = "$buildDir/test-results/SuiteTwo")
   reports.html.destination = "$buildDir/test-results/SuiteTwo")
}
