use of io.netty.util.internal.ThreadLocalRandom in project netty by netty.

the class LongPriorityQueueTest method internalRemoveMustPreserveOrder.

@Test

    ThreadLocalRandom tlr = ThreadLocalRandom.current();
    int initialValues = tlr.nextInt(1, 30);
    ArrayList<Long> values = new ArrayList<Long>();
    LongPriorityQueue pq = new LongPriorityQueue();
    for (int i = 0; i < initialValues; i++) {
        long value = tlr.nextLong(0, Long.MAX_VALUE);
        pq.offer(value);
        values.add(value);
    }
    long toRemove = values.get(values.size() / 2);
    values.remove(toRemove);
    pq.remove(toRemove);
    Collections.sort(values);
    for (Long value : values) {
        assertThat(pq.poll()).isEqualTo(value);
    }
    assertTrue(pq.isEmpty());
