我想比較兩個測試列表。 我有這個代碼如何檢查通用列表與jUnit是否相等?
@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。
我找回這個錯誤

更新
public boolean equals(Point b) {
if(this.i == b.i && this.j == b.j) return true;
else return false;
}
如何解決這個問題呢?
,你能否告訴我們'Point.equals(對象)'執行?除非這是正確的,否則它將不起作用。 –
您可以在斷言前打印出「actual」和「expected」的內容嗎? – Marvo
@PeterLawrey謝謝。我知道我的錯誤在哪裏。 – BILL
