@BeforeClass of jUnit is called multiple times

Question

I am new to jUnit, running jUnit testing with @BeforeClass and @Test methods. The problem is my @BeforeClass method is called not once (like it's supposed to) but every time before @Test method. Same thing happens with @AfterClass - it runs after each @Test method. Here's the code:

import static org.junit.Assert.*;
import org.junit.Test;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.After;
import org.junit.AfterClass;
import java.util.*;

public class MatrixTest {

@BeforeClass
public static void testAdd() {
    System.out.println("Before class");
}

@Test
public void testValueSet() {
    System.out.println("Hello 1");
}

 @Test
  public void testMultiply() {
    System.out.println("Hello 2");
  }

 @Test
  public void testGetDiagonalSum() {
    System.out.println("Hello 3"); 
   }

Output:
Before class
Hello 3
Before class
Hello 2
Before class
Hello 1

Any help would be greatly appreciated. Thanks in advance!

There is no issue here. Make sure you are executing by running as JUnit test.
