在java中模拟多级数组进行单元测试

public class MultiDimensionalArray {
    private int[][] array;

    public MultiDimensionalArray(int rows, int columns) {
        array = new int[rows][columns];
    }

    public void setValue(int row, int column, int value) {
        array[row][column] = value;
    }

    public int getValue(int row, int column) {
        return array[row][column];
    }
}

import org.junit.Test;
import static org.junit.Assert.*;

public class MultiDimensionalArrayTest {
    @Test
    public void testSetValueAndGetValue() {
        MultiDimensionalArray array = new MultiDimensionalArray(3, 3);
        array.setValue(0, 0, 1);
        array.setValue(1, 1, 2);
        array.setValue(2, 2, 3);

        assertEquals(1, array.getValue(0, 0));
        assertEquals(2, array.getValue(1, 1));
        assertEquals(3, array.getValue(2, 2));
    }
}
