Struct exonum_btc_anchoring::test_helpers::AnchoringTestKit

pub struct AnchoringTestKit {
    pub inner: TestKit,
    // some fields omitted
}

Convenient wrapper around testkit with the built-in bitcoin key pool for the each anchoring node.

Fields

inner: TestKit

Underlying testkit instance.

Methods

impl AnchoringTestKit

pub fn new(nodes_num: u16, anchoring_interval: u64) -> Self

Creates an anchoring testkit instance for the specified number of anchoring nodes, and interval between anchors.

pub fn actual_anchoring_config(&self) -> Config

Returns the actual anchoring configuration.

pub fn last_anchoring_tx(&self) -> Option<Transaction>

Returns the latest anchoring transaction.

pub fn anchoring_transaction_proposal(
    &self
) -> Option<(Transaction, Vec<Transaction>)>

Returns the proposal of the next anchoring transaction for the actual anchoring state.

pub fn create_signature_tx_for_node(
    &self,
    node: &TestNode
) -> Result<Vec<Verified<AnyTx>>, BuilderError>

Creates signatures for each input of the proposed anchoring transaction signed by the specified node.

pub fn create_signature_txs(&self) -> Vec<Vec<Verified<AnyTx>>>

Creates signatures for each input of the proposed anchoring transaction signed by all of anchoring nodes.

pub fn create_funding_confirmation_txs(
    &self,
    satoshis: u64
) -> (Vec<Verified<AnyTx>>, Transaction)

Creates the confirmation transactions with a funding transaction to the current address with a given amount of Satoshi.

pub fn create_funding_confirmation_txs_with(
    &self,
    transaction: Transaction
) -> Vec<Verified<AnyTx>>

Creates the confirmation transactions with a specified funding transaction.

pub fn create_config_change_tx(
    &self,
    proposal: ConfigPropose
) -> Verified<AnyTx>

Creates configuration change transaction for simple supervisor.

pub fn add_node(&mut self) -> AnchoringKeys

Adds a new auditor node to the testkit network and create Bitcoin keypair for it.

pub fn node_private_key(&self, public_key: &PublicKey) -> PrivateKey

Returns a corresponding private Bitcoin key.

pub fn gen_bitcoin_key(&mut self) -> PublicKey

Generates bitcoin keypair and adds them to the key pool.

pub fn block_hash_on_height(&self, height: Height) -> Hash

Returns the block hash for the given blockchain height.

pub fn anchoring_keypairs(
    &self
) -> impl IntoIterator<Item = (PublicKey, PrivateKey)>

Returns Bitcoin key pairs of anchoring nodes.

pub fn find_anchoring_node(&self, bitcoin_key: &PublicKey) -> Option<&TestNode>

Finds anchoring node with the specified bitcoin key.

Trait Implementations

impl Debug for AnchoringTestKit

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for AnchoringTestKit

fn default() -> Self

Creates anchoring testkit instance with the unspent funding transaction.

To add funds, this instance commit a block with transactions, so in addition to the genesis block this instance contains one more.
