Class QueueIteratorTest

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.eigenbase.runtime.QueueIteratorTest

All Implemented Interfaces:

Test

public class QueueIteratorTest
extends TestCase

Test case for QueueIteratorTest.TestingTimeoutQueueIterator and its subclasses ThreadIterator and QueueIteratorTest.TestingTimeoutQueueIterator.

Nested Class Summary

private static class	QueueIteratorTest.TestingTimeoutQueueIterator A TimeoutQueueIterator that exposes its inner QueueIterator for direct reading.
private static class	QueueIteratorTest.TickIterator Iterator which returns an element from an array on a regular basis.

Field Summary

private static String[]	queueValues Contents of queue in both tests.
private long	startTime Timestamp at which the test started.
private static int	tickMillis Multiplier which determines how long each logical clock tick lasts, and therefore how fast the test is run.

Constructor Summary

QueueIteratorTest(String s)

Method Summary

private void	assertHasNext(QueueIterator iter, boolean expected, long timeoutMillis)
private void	assertHasNextTimesOut(QueueIterator iter, long timeoutMillis)
private void	assertNext(QueueIterator iter, Object expected, long timeoutMillis)
private void	assertNextTimesOut(QueueIterator iter, long timeoutMillis)
private void	read(QueueIterator iter)
void	testThreadIterator()
void	testTimeoutIterator()
private long	toMillis(double tick)

Field Detail

tickMillis

private static final int tickMillis

Multiplier which determines how long each logical clock tick lasts, and therefore how fast the test is run. If you are getting sporadic problems, raise the value. 100 seems to be too low; 200 seems to be OK on my 1.8GHz laptop.

Constant Field Values

queueValues

private static final String[] queueValues

startTime

private long startTime

Timestamp at which the test started. All timeouts are relative to this.
