Attempt to debug ONLY method of parameterized class failed with exception in console
package junitfaq;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.Test;
import org.junit.Ignore;
import static org.junit.Assert.*;
import java.util.LinkedList;
@RunWith(Parameterized.class)
public class AdditionTest {
private int x, y;
public AdditionTest(int x, int y) { this.x = x; this.y = y; }
@Test
public void addition() { int z = x + y; assertEquals(2, z); }
@Ignore
@Test
public void additionAgain() { // }
@Parameterized.Parameters
public static LinkedList data() {
LinkedList params = new LinkedList();
params.add(new Integer[] {1, 1});
return params;
}
}
P.S. I tried to debug addition() method.
