Module test_utils 

Property test strategies and shared test fixtures.

Enables integration tests to use strategies that satisfy Orange Paper constraints (e.g. |w| = |tx.inputs| for SegWit round-trip) and shared UTXO-set helpers.

Functions

create_coinbase_tx

Create a valid coinbase transaction (scriptSig 2–100 bytes per consensus). Shared by integration tests so fixture behavior stays consistent.

create_test_header

Create a block header with the given timestamp and previous block hash. Shared by integration tests so fixture behavior stays consistent.

create_test_utxo_set_two_outputs

UTXO set with two outputs for fee-calculation style tests (1 BTC and 0.5 BTC). Shared by integration tests so fixture behavior stays consistent.

transaction_strategy

Strategy yielding Transaction for legacy (non-SegWit) round-trip tests.

transaction_with_witness_strategy

Strategy yielding (Transaction, Vec) with |w| = |tx.inputs|. Use for SegWit round-trip property tests per Orange Paper 8.2.2.
