Example 1 with Repeat

use of com.pushtorefresh.storio3.test.Repeat in project storio by pushtorefresh.

the class RxQueryTest method concurrentPutWithoutGlobalTransaction.

@Test
@Repeat(times = 20)
public void concurrentPutWithoutGlobalTransaction() throws InterruptedException {
    final int numberOfConcurrentPuts = ConcurrencyTesting.optimalTestThreadsCount();
    TestSubscriber<Changes> testSubscriber = new TestSubscriber<Changes>();
    storIOSQLite.observeChangesInTable(TweetTableMeta.TABLE, LATEST).subscribe(testSubscriber);
    final CountDownLatch concurrentPutLatch = new CountDownLatch(1);
    final CountDownLatch allPutsDoneLatch = new CountDownLatch(numberOfConcurrentPuts);
    for (int i = 0; i < numberOfConcurrentPuts; i++) {
        final int iCopy = i;
        new Thread(new Runnable() {

            @Override
            public void run() {
                try {
                    concurrentPutLatch.await();
                } catch (InterruptedException e) {
                    throw new RuntimeException(e);
                }
                storIOSQLite.put().object(Tweet.newInstance(null, 1L, "Some text: " + iCopy)).prepare().executeAsBlocking();
                allPutsDoneLatch.countDown();
            }
        }).start();
    }
    // Start concurrent Put operations.
    concurrentPutLatch.countDown();
    assertThat(allPutsDoneLatch.await(25, SECONDS)).isTrue();
    testSubscriber.assertNoErrors();
    // Put operation creates short-term transaction which might result in merge of some notifications.
    // So we have two extreme cases:
    // - no merged notifications → isEqualTo(numberOfParallelPuts)
    // - all notifications merged → isEqualTo(1)
    // Obviously truth is somewhere between those (depends on CPU of machine that runs test).
    assertThat(testSubscriber.valueCount()).isLessThanOrEqualTo(numberOfConcurrentPuts).isGreaterThanOrEqualTo(1);
}
