Example 46 with PipedOutputStream

use of java.io.PipedOutputStream in project Hystrix by Netflix.

    verifyStream(is, writes);
    // Let the provider stream for some time.
    Thread.sleep(1000);
    // Stop streaming
    streamingThread.interrupt();
    os.close();
    is.close();
    System.out.println("Total lines:" + writes.get());
    // Observable is configured to emit events in every 100 ms. So expect at least 9 in a second.
    assertTrue(writes.get() >= 9);
    // Provider is expected to decrement connection count when streaming process is terminated.
    assertTrue(hasNoMoreConcurrentConnections(stream.getConcurrentConnections(), 200, 10, TimeUnit.MILLISECONDS));
