Example 1 with StubSyncSource

use of tech.pegasys.teku.networking.eth2.peers.StubSyncSource in project teku by ConsenSys.

protected Batch createBatch(final long startSlot, final long count) {
    final List<StubSyncSource> syncSources = new ArrayList<>();
    final SyncSourceSelector syncSourceProvider = () -> {
        final StubSyncSource source = new StubSyncSource();

    return batch;
}

Example 2 with StubSyncSource

use of tech.pegasys.teku.networking.eth2.peers.StubSyncSource in project teku by ConsenSys.

the class SyncSourceBatchTest method requestMoreBlocks_shouldResetAndSelectNewPeerAfterDisconnection.

@Test

    final Runnable callback = mock(Runnable.class);
    final Batch batch = createBatch(70, 50);

    verify(callback).run();
    batch.markFirstBlockConfirmed();

    assertThatBatch(batch).isNotEmpty();
    // But this requests fails
    firstSyncSource.failRequest(new PeerDisconnectedException());
    // The request is complete, so should call the callback
    verify(callback, times(2)).run();
