To create a test suite we will use the annotation @RunWith and @Suite.SuiteClasses. We will create a TestSuite class and annotate it with these two annotations. 
package junits;
 
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
 
@RunWith(Suite.class)
@Suite.SuiteClasses({
      JunitMathProvider_1.class,
      JunitMathProvider_2.class
         })
 
public class TestSuite {
 }
Hope this helps you:)
