JUnit 4 Tutorial , Parameterized Test

import static org.junit.Assert.*; import java.util.Arrays; import java.util.Collection; import org.junit.Test; import org.junit.runner.RunWith; import org.junit.runners.Parameterized; import org.junit.runners.Parameterized.Parameters; @RunWith(Parameterized.class) public class SimpleMathTest {     public static class SimpeMath {         public static int Add(int a, int b) {             return a + b;         }     }     int a, b, expected;     public SimpleMathTest(int a, int b, int expected) {         super();         this.a = a;         this.b = b;         this.expected = expected;     }     @Parameters     public static Collection < Object[] > TestThoseSeries() {         Object[][] data = new Object[][] {             {                 1, 2, 3             }, {                 2, 2, 4             }, {                 3, 3, 6             }, {                 4, 4, 9             }         };         return Arrays.asList(data);     }     @Test     public void testAdd() {         assertSame(expected, SimpeMath.Add(a, b));     } }

you will see 3 passed, one failed when you run the test.
