### Question:
Board extends AbstractBoard<Elements> { public boolean isBulletAt(int x, int y) { return getAt(x, y).equals(Elements.BULLET); }  @Override Elements valueOf(char ch); boolean isBarrierAt(int x, int y); List<Point> getBarriers(); Point getMe(); List<Point> getEnemies(); List<Point> getBullets(); boolean isGameOver(); Elements getAt(int x, int y); boolean isBulletAt(int x, int y); @Override String toString();  }### Answer:
@Test public void shouldWork_isBulletAt() { assertEquals(true, board.isBulletAt(1, 8)); assertEquals(false, board.isBulletAt(2, 8)); assertEquals(false, board.isBulletAt(-2, -8)); }
