Here's a canonical example of an "expected timeout" test that seems natural
and readable to me.
timeoutMillis() returns 12ms, adjusted by timeout factor. Ldap might need
a bigger value.
/**
* timed await times out if not counted down before timeout
*/
public void testAwaitTimeout() throws InterruptedException {
final CountDownLatch l = new CountDownLatch(1);
Thread t = newStartedThread(new CheckedRunnable() {
public void realRun() throws InterruptedException {
assertEquals(1, l.getCount());
long startTime = System.nanoTime();
assertFalse(l.await(timeoutMillis(), MILLISECONDS));
assertTrue(millisElapsedSince(startTime) >=
timeoutMillis());
assertEquals(1, l.getCount());
}});
awaitTermination(t);
assertEquals(1, l.getCount());
}
