Examples with TestClock org.hyperledger.besu.testutil.TestClock used on opensource projects

Example 1 with TestClock

use of org.hyperledger.besu.testutil.TestClock in project besu by hyperledger.

the class TransitionsTest method transitionsBlockPeriod.

@Test
public void transitionsBlockPeriod() throws InterruptedException {
    final TestClock clock = new TestClock(Instant.EPOCH);
    final List<BftFork> bftForks = List.of(new BftFork(JsonUtil.objectNodeFromMap(Map.of(BftFork.FORK_BLOCK_KEY, 1, BftFork.BLOCK_PERIOD_SECONDS_KEY, 10))), new BftFork(JsonUtil.objectNodeFromMap(Map.of(BftFork.FORK_BLOCK_KEY, 2, BftFork.BLOCK_PERIOD_SECONDS_KEY, 20))));
    final BftEventQueue bftEventQueue = new BftEventQueue(TestContextBuilder.MESSAGE_QUEUE_LIMIT);
    final TestContext context = new TestContextBuilder().indexOfFirstLocallyProposedBlock(0).validatorCount(1).clock(clock).bftForks(bftForks).eventQueue(bftEventQueue).buildAndStart();
    clock.stepMillis(10_000);
    context.getEventMultiplexer().handleBftEvent(bftEventQueue.poll(1, TimeUnit.SECONDS));
    context.getController().handleNewBlockEvent(new NewChainHead(context.getBlockchain().getChainHeadHeader()));
    clock.stepMillis(20_000);
    context.getEventMultiplexer().handleBftEvent(bftEventQueue.poll(1, TimeUnit.SECONDS));
    final BlockHeader genesisBlock = context.getBlockchain().getBlockHeader(0).get();
    final BlockHeader blockHeader1 = context.getBlockchain().getBlockHeader(1).get();
    final BlockHeader blockHeader2 = context.getBlockchain().getBlockHeader(2).get();
    assertThat(blockHeader1.getTimestamp()).isEqualTo(genesisBlock.getTimestamp() + 10);
    assertThat(blockHeader2.getTimestamp()).isEqualTo(blockHeader1.getTimestamp() + 20);
