Usage

From source file:org.apache.gobblin.writer.ThrottleWriterTest.java

public void testThrottleBytes() throws IOException {
    DataWriter<Void> writer = mock(DataWriter.class);
    final MutableLong mockBytes = new MutableLong();
    when(writer.bytesWritten()).thenAnswer(new Answer<Long>() {
        @Override/*from ww w.  j a va 2  s  .  c  o m*/
        public Long answer(InvocationOnMock invocation) throws Throwable {
            mockBytes.add(1L); //Delta bytes
            return mockBytes.getValue();
        }
    });

    int parallelism = 2;
    int bps = 2;
    DataWriter<Void> throttleWriter = setup(writer, parallelism, bps, ThrottleType.Bytes);

    int count = 0;
    long duration = 10L;
    Stopwatch stopwatch = Stopwatch.createStarted();
    while (stopwatch.elapsed(TimeUnit.SECONDS) <= duration) {
        throttleWriter.writeEnvelope(null);
        count++;
    }

    int expected = (int) (bps * duration);
    Assert.assertTrue(count <= expected + bps * 2);
    Assert.assertTrue(count >= expected - bps * 2);
