java - 如何检查通用列表与 jUnit 是否相等？

Question

我想在测试中比较两个列表。我有这个代码

@Test
public void testGetVerticalCells() 
{
    int[][] m = new int[][] 
            {
                { 1, 0, 1 }, 
                { 1, 1, 0 }, 
                { 0, 1, 1 } 
            };
    int i = 1;
    int j = 2;
    Point sPoint = new Point(i, j);
    potentialAlgorithm.startPoint = sPoint;
    List<Point> actuals = potentialAlgorithm.getVerticalCells(m, i, j);
    List<Point> expecteds = new ArrayList<Point>() {
        {
            add(new Point(0, 2));
            add(new Point(2, 2));
        }
    };
    assertTrue(actuals.containsAll(expecteds));
}

我使用 jUnit 4.11。

我检索到此错误

更新

public boolean equals(Point b) {
    if(this.i == b.i && this.j == b.j) return true;
    else return false;
}

如何解决这个问题？

解决方案比想象的要简单:

assertTrue(actuals.equals(expected));
