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. + +## Public Key Recovery Tests (PR #120) + +The `test_key_recovery.py` file contains fully implemented tests for public key recovery from message and signature functionality from PR #120. These tests verify: + +- Recovery of public keys from message signatures +- Error handling for invalid signature length +- Error handling for invalid recovery ID +- Error handling for missing parameters +- Error handling for empty messages + +The tests use predefined test vectors with known messages, signatures, and corresponding public keys to verify the recovery process works correctly. + +### Running the Public Key Recovery Tests + +To run the public key recovery tests specifically: + +```bash +pytest -xvs tests/test_key_recovery.py +``` + +### Extending Public Key Recovery Tests + +To add more test cases for public key recovery: +1. Add new test vectors (message, signature, expected public key) +2. Follow the pattern in the `TestPublicKeyRecovery` class +3. Ensure proper validation of error cases + +## 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.
