designed to work without requiring an active Bitcoin node connection or live network. Instead, they use a mock data approach to simulate Bitcoin network operations. + +Key features of our testing approach: +- **Mock Data**: Pre-defined test vectors are stored in JSON files in the `mock_data` directory +- **Isolation**: Tests run independently of any live Bitcoin network +- **Reproducibility**: Fixed inputs ensure consistent test results +- **Comprehensive Coverage**: Tests cover edge cases and error handling + +## Test Organization + +The tests are organized by functionality: +- **Key and Address Tests**: Tests for private/public keys and address generation +- **Transaction Tests**: Tests for creating and signing various transaction types +- **Script Tests**: Tests for Bitcoin Script operations + +## Mock Data + +Mock data is stored in JSON files in the `tests/mock_data` directory. These files contain test vectors for various scenarios. + +## Message Signature Tests (PR #120) + +The `test_public_key_recovery.py` file contains tests for public key recovery from message and signature functionality (PR #120). Most of these tests are currently skipped as they require the implementation from PR #120. + +Once PR #120 is merged, these tests will verify: +- Recovery of public keys from message signatures +- Error handling for various invalid inputs +- Functionality of the `from_message_signature` class method + +The tests use mock data from `message_signature_data.json`, which contains test vectors for message signature operations. + +## Running Tests + +To run all tests: +```bash +python -m unittest discover tests +``` + +To run a specific test file: +```bash +python -m unittest tests.test_file_name +``` + +## Adding New Tests + +When adding new tests: +1. Create appropriate mock data in the `tests/mock_data` directory +2. Create test classes extending `unittest.TestCase` +3. Use the mock data in your tests instead of making live network calls +4. Update this README with information about your new tests + +## Test Dependencies + +The tests require the following packages: +- unittest (standard library) +- json (standard library) +- os (standard library) + +## Examples + +### Example 1: Testing with Mock Transaction Data + +```python +import unittest +import json +import os +from bitcoinutils.transactions import Transaction + +class TestTransactions(unittest.TestCase): + @classmethod + def setUpClass(cls): + # Load mock data + mock_data_path = os.path.join('tests', 'mock_data', 'transaction_data.json') + with open(mock_data_path, 'r') as file: + cls.mock_data = json.load(file) + + def test_transaction_parsing(self): + # Use mock transaction data + raw_tx = self.mock_data['valid_transactions'][0]['raw'] + tx = Transaction.from_raw(raw_tx) + + # Verify transaction properties + self.assertEqual(tx.version, self.mock_data['valid_transactions'][0]['version']) + self.assertEqual(len(tx.inputs), self.mock_data['valid_transactions'][0]['input_count']) +``` + +### Example 2: Using Mock Data for Keys and Addresses + +```python +import unittest +import json +import os +from bitcoinutils.setup import setup +from bitcoinutils.keys import PrivateKey, PublicKey + +class TestKeysAndAddresses(unittest.TestCase): + @classmethod + def setUpClass(cls): + # Set up the network + setup('testnet') + + # Load mock data + mock_data_path = os.path.join('tests', 'mock_data', 'key_address_data.json') + with open(mock_data_path, 'r') as file: + cls.mock_data = json.load(file) + + def test_address_generation(self): + # Use mock private key data + priv_key_wif = self.mock_data['private_keys'][0]['wif'] + expected_address = self.mock_data['private_keys'][0]['address'] + + # Create private key and derive address + priv_key = PrivateKey(priv_key_wif) + pub_key = priv_key.get_public_key() + address = pub_key.get_address() + + # Verify address matches expected + self.assertEqual(address.to_string(), expected_address) +``` + +These examples demonstrate how to use mock data in your tests without relying on live network connections. \ No newline at end of file diff --git a/apply_patches.py b/apply_patches.py deleted file mode 100644 index 3e8b2caf..00000000 --- a/apply_patches.py +++ /dev/null @@ -1,658 +0,0 @@ -# apply_patches.py -""" -Apply necessary patches to Bitcoin utilities for testing. -This module applies monkey patches to fix various issues with the bitcoinutils library. -""" -
