In JUnit, you can run multiple test cases with @RunWith and @Suite annotation. Refer to the following examples :

SuiteAbcTest.java

package com.mkyong;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
@Suite.SuiteClasses({
        Exception1Test.class, //test case 1
        TimeoutTest.class     //test case 2
})
public class SuiteAbcTest {
	//normally, this is an empty class
}

P.S Tested with JUnit 4.12
