key-wallet/src/test_utils/utxo.rs (1)
7-40: Consider parameterizing the network for broader test coverage.The dummy constructors currently hardcode
Network::Testnet(Line 32), which prevents creating dummy UTXOs for mainnet tests. According to coding guidelines, tests should cover both mainnet and testnet configurations. Consider adding a network parameter todummyanddummy_batchmethods, or providing separate constructors for each network.As per coding guidelines, tests should cover both mainnet and testnet configurations.
♻️ Proposed refactor
impl Utxo { - pub fn dummy(id: u8, value: u64, height: u32, coinbase: bool, confirmed: bool) -> Self { - Self::dummy_batch(id..id + 1, value, height, coinbase, confirmed).remove(0) + pub fn dummy(network: Network, id: u8, value: u64, height: u32, coinbase: bool, confirmed: bool) -> Self { + Self::dummy_batch(network, id..id + 1, value, height, coinbase, confirmed).remove(0) } pub fn dummy_batch( + network: Network, ids_range: Range<u8>, value: u64, height: u32, coinbase: bool, confirmed: bool, ) -> Vec<Self> { ids_range .enumerate() .map(|(i, id)| { let outpoint = OutPoint::new(Txid::from([id; 32]), i as u32); let txout = TxOut { value, script_pubkey: ScriptBuf::new(), }; let mut utxo = Utxo::new( outpoint, txout, - Address::dummy(Network::Testnet, id as usize), + Address::dummy(network, id as usize), height, coinbase, ); utxo.is_confirmed = confirmed; utxo }) .collect() } }key-wallet-manager/src/test_utils/wallet.rs (3)
11-40: Add documentation for test mock API.The
MockWalletstruct and its public methods lack documentation explaining their purpose, usage patterns, and how they differ from real wallet implementations. This is especially important for test utilities that will be used across multiple crates.📝 Suggested documentation structure
+/// Mock wallet implementation for testing purposes. +/// +/// This mock records all block and transaction processing operations and allows +/// pre-configuring transaction effects for testing. Unlike real wallets, it: +/// - Returns ALL transactions in a block as "relevant" +/// - Always returns true for compact filter checks +/// - Does not perform actual cryptographic operations +/// +/// # Example +/// ```no_run +/// let mut wallet = MockWallet::new(); +/// wallet.set_effect(txid, 1000, vec!["address1".to_string()]).await; +/// ``` pub struct MockWallet {
19-26: Consider simplifying constructor with Default trait.Since
MockWalletderivesDefault, thenew()method could delegate toSelf::default()for consistency.♻️ Simplified implementation
impl MockWallet { pub fn new() -> Self { - Self { - processed_blocks: Arc::new(Mutex::new(Vec::new())), - processed_transactions: Arc::new(Mutex::new(Vec::new())), - effects: Arc::new(Mutex::new(BTreeMap::new())), - } + Self::default() }
83-86: Consider simplifying constructor with Default trait.The
new()method is redundant with the derivedDefaulttrait.♻️ Simplified implementation
impl NonMatchingMockWallet { pub fn new() -> Self { - Self {} + Self::default() } }dash/src/test_utils/mod.rs (1)
1-6: Add module-level documentation.The test utilities module lacks documentation explaining what utilities are provided and how they should be used. This is important for discoverability across the workspace.
📝 Suggested documentation
+//! Test utilities for the dashcore crate. +//! +//! This module provides dummy constructors and test helpers for various +//! Dash types to facilitate deterministic testing. Available utilities: +//! +//! - `Address::dummy()` - Generate test addresses +//! - `Block::dummy()` - Generate test blocks and headers +//! - `ChainLock::dummy()` - Generate test chain locks +//! - `FilterHeader::dummy()` - Generate test filter headers +//! - `InstantLock::dummy()` - Generate test instant locks +//! - `Transaction::dummy()` - Generate test transactions +//! +//! These utilities are only available when the `test-utils` feature is enabled +//! or when building tests. + mod address; mod block; mod chainlock; mod filter; mod instantlock; mod transaction;dash-spv/src/test_utils/chain_tip.rs (2)
6-8: Consider parameterizing the network for test flexibility.The method hardcodes
Network::Dash, which limits testing flexibility. According to coding guidelines and learnings, tests should cover both mainnet and testnet configurations.♻️ Proposed enhancement
- pub fn dummy(height: u32, work_value: u8) -> ChainTip { - let mut header = genesis_block(Network::Dash).header; + pub fn dummy(network: Network, height: u32, work_value: u8) -> ChainTip { + let mut header = genesis_block(network).header; header.nonce = height; // Make it unique let chain_work = ChainWork::dummy(work_value); ChainTip::new(header, height, chain_work) }Or provide separate convenience methods:
pub fn dummy_mainnet(height: u32, work_value: u8) -> ChainTip { Self::dummy(Network::Dash, height, work_value) } pub fn dummy_testnet(height: u32, work_value: u8) -> ChainTip { Self::dummy(Network::Testnet, height, work_value) }Based on learnings, tests should cover both mainnet and testnet configurations.
1-14: Add documentation explaining test-only behavior.The
dummyconstructor lacks documentation and uses non-realistic values (nonce for uniqueness rather than proof-of-work). This should be clearly documented for test utility users.📝 Suggested documentation
impl ChainTip { + /// Creates a dummy ChainTip for testing purposes. + /// + /// This constructor creates a ChainTip with non-realistic values: + /// - Uses the genesis block header as a base + /// - Sets `nonce` to the `height` value for uniqueness (not actual PoW) + /// - Uses a dummy ChainWork derived from `work_value` + /// + /// # Parameters + /// - `height`: Block height, also used as nonce for uniqueness + /// - `work_value`: Value passed to `ChainWork::dummy()` for chain work calculation + /// + /// # Note + /// This is for testing only. Real blockchain headers have nonces derived from + /// proof-of-work mining, not arbitrary height values. pub fn dummy(height: u32, work_value: u8) -> ChainTip { let mut header = genesis_block(Network::Dash).header; header.nonce = height; // Make it unique let chain_work = ChainWork::dummy(work_value); ChainTip::new(header, height, chain_work) } }key-wallet/src/wallet/managed_wallet_info/coin_selection.rs (1)
744-750: Consider using unique UTXO IDs for better test robustness.While using
id=0for all test UTXOs works for these specific tests, consider whether future tests might benefit from unique IDs. This could help catch issues related to UTXO identification and prevent subtle bugs if the implementation ever relies on unique identifiers.💡 Optional enhancement for future consideration
let utxos = vec![ - Utxo::dummy(0, 100, 100, false, true), - Utxo::dummy(0, 200, 100, false, true), - Utxo::dummy(0, 300, 100, false, true), - Utxo::dummy(0, 500, 100, false, true), - Utxo::dummy(0, 1000, 100, false, true), - Utxo::dummy(0, 2000, 100, false, true), + Utxo::dummy(1, 100, 100, false, true), + Utxo::dummy(2, 200, 100, false, true), + Utxo::dummy(3, 300, 100, false, true), + Utxo::dummy(4, 500, 100, false, true), + Utxo::dummy(5, 1000, 100, false, true), + Utxo::dummy(6, 2000, 100, false, true), ];This change is not required for correctness but could improve test robustness if UTXO identification becomes relevant in future implementations.

1-22: Consider parameterizing the network for flexibility.The dummy constructor hardcodes
Network::Testnetat line 10. While this works for most test scenarios, consider adding a network parameter to support both mainnet and testnet testing, consistent with the coding guideline to test both configurations.♻️ Optional refactor to parameterize network
impl InstantLock { - pub fn dummy(transaction_input_ids: Range<u8>) -> InstantLock { - let address = Address::dummy(crate::Network::Testnet, 0); + pub fn dummy(network: crate::Network, transaction_input_ids: Range<u8>) -> InstantLock { + let address = Address::dummy(network, 0); let tx = Transaction::dummy(&address, transaction_input_ids, &[COIN_VALUE]); let inputs = tx.input.iter().map(|input| input.previous_output).collect(); InstantLock { version: 1, inputs, txid: tx.txid(), signature: BLSSignature::from([1; 96]), cyclehash: BlockHash::dummy(0), } } }As per coding guidelines: Test both mainnet and testnet configurations.
8-22: Add documentation for the dummy constructor.Consider adding a doc comment explaining the purpose of this test utility and when to use it. This helps maintain clarity as the codebase grows.
📝 Suggested documentation
impl InstantLock { + /// Creates a dummy InstantLock for testing purposes. + /// + /// # Parameters + /// * `transaction_input_ids` - Range of input IDs to include in the transaction + /// + /// # Note + /// This creates an InstantLock with placeholder values suitable for testing. + /// The signature and cyclehash are not cryptographically valid. pub fn dummy(transaction_input_ids: Range<u8>) -> InstantLock {dash/src/test_utils/transaction.rs (1)
17-23: Consider more appropriate script_sig for test realism.Line 19 sets
script_sigtoaddress.script_pubkey(), which is semantically incorrect. Thescript_sigshould contain an unlocking script (signature + public key), whilescript_pubkeyis the locking script. This makes the dummy transactions technically invalid.For test utilities that don't validate scripts, this may be acceptable, but it could cause issues if any tests attempt script validation. Consider either:
- Using an empty script_sig (
ScriptBuf::new()) to clearly indicate these are invalid/dummy transactions- Documenting this limitation in a comment
- If script validation is needed, generating a proper unlocking script
💡 Suggested documentation or alternative
Option 1: Add a comment explaining the limitation:
TxIn { previous_output: OutPoint::new(Txid::from(txid_bytes), i as u32), + // Note: Using script_pubkey as script_sig for dummy data. + // These transactions are not script-valid. script_sig: address.script_pubkey(), sequence: 0xffffffff, witness: Witness::new(), }Option 2: Use empty script_sig:
TxIn { previous_output: OutPoint::new(Txid::from(txid_bytes), i as u32), - script_sig: address.script_pubkey(), + script_sig: ScriptBuf::new(), // Dummy transaction, no valid unlocking script sequence: 0xffffffff, witness: Witness::new(), }dash-spv/src/test_utils/checkpoint.rs (1)
7-31: Consider documenting the dummy constructor's test data patterns.The
dummyconstructor generates deterministic test data with specific patterns (e.g., masternode list names only at 100k block intervals, chain work asheight * 1000). Adding a doc comment explaining these patterns would help test authors understand what test data they're working with.📝 Suggested documentation
impl Checkpoint { + /// Creates a dummy checkpoint for testing purposes. + /// + /// Generates deterministic test data: + /// - Block hashes derived from height + /// - Chain work: 0x{height * 1000} + /// - Fixed target: 0x1d00ffff + /// - Masternode list names only at heights that are multiples of 100,000 pub fn dummy(height: u32, timestamp: u32) -> Checkpoint {dash-spv/src/validation/instantlock.rs (1)
122-122: Remove redundant import.The
use dashcore_hashes::Hash;statement is redundant asHashis already imported at line 4 at the module level and is available to the test module.♻️ Proposed fix
#[cfg(test)] mod tests { use super::*; - use dashcore_hashes::Hash;
