You can use produce_blocks to help achieve an arbitrary block height; this is useful when you want to do any testing regarding transaction maturity.

Note: For the produce_blocks API to work, it is imperative to have manual_blocks_enabled = true in the config for the running node. See example below.

    let config = Config {
manual_blocks_enabled: true, // Necessary so the `produce_blocks` API can be used locally
..Config::local_node()
    };
    let wallets =
launch_custom_provider_and_get_wallets(WalletsConfig::default(), Some(config), None).await;
    let wallet = &wallets[0];
    let provider = wallet.try_provider()?;
 
    assert_eq!(provider.latest_block_height().await?, 0u32);
 
    provider.produce_blocks(3, None).await?;
 
    assert_eq!(provider.latest_block_height().await?, 3u32);

You can also set a custom block time as the second, optional argument. Here is an example:

    let config = Config {
manual_blocks_enabled: true, // Necessary so the `produce_blocks` API can be used locally
block_production: Trigger::Interval {
    block_time: Duration::from_secs(10),
},
..Config::local_node()
    };
    let wallets =
launch_custom_provider_and_get_wallets(WalletsConfig::default(), Some(config), None).await;
    let wallet = &wallets[0];
    let provider = wallet.try_provider()?;
 
    assert_eq!(provider.latest_block_height().await?, 0u32);
 
    provider
.produce_blocks(3, Some(Utc.timestamp_opt(100, 0).unwrap()))
.await?;
 
    assert_eq!(provider.latest_block_height().await?, 3u32);
 
    let req = PaginationRequest {
cursor: None,
results: 10,
direction: PageDirection::Forward,
    };
    let blocks: Vec<Block> = provider.get_blocks(req).await?.results;
 
    assert_eq!(blocks[1].header.time.unwrap().timestamp(), 100);
    assert_eq!(blocks[2].header.time.unwrap().timestamp(), 110);
    assert_eq!(blocks[3].header.time.unwrap().timestamp(), 120);
