标题: junit参数化测试方法报错
今天尝试了一把，junit4 参数化测试方法，报错了，求哪位高手解决。
代码贴一下：
import static org.junit.Assert.*;
import java.util.Arrays;
import java.util.Collection;
import junit.framework.Assert;
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 AddTest {
private Add add =new Add();
private int input1;
private int input2;
private int expected;
@Parameters
public static Collection<Object[]> data(){
Object[][] object=new Object[][]{{1,2, 3},{2,3,5}};
return Arrays.asList(object);
}
public void getParameter(int input1,int input2,int expected){
this.expected=expected;
this.input1=input1;
this.input2=input2;
}
@Test
public void testAdd() {
Assert.assertEquals(expected, add.add(input1,input2));
}

}

运行后错误提示：

运行环境：junit4.8.2 +jdk1.6

感觉像出在这里：new Object[][]{{1,2, 3},{2,3,5}};
