## 🔒 **Security Validation**
### **Attack Prevention Tests**
- ✅ **Consensus**: Double signing, key compromise, Byzantine attacks
- ✅ **Network**: Sybil attacks, DDoS, message tampering
- ✅ **Economics**: Reward manipulation, gas price manipulation, staking attacks
- ✅ **Agents**: Authentication bypass, reputation manipulation, communication hijacking
- ✅ **Contracts**: Double spend, escrow manipulation, dispute bias
### **Security Requirements**
```python
# Example security test
def test_double_signing_detection(self):
"""Test detection of validator double signing"""
# Simulate double signing
event = mock_slashing.detect_double_sign(
validator_address, block_hash_1, block_hash_2, block_height
)
assert event is not None
assert event.validator_address == validator_address
mock_slashing.apply_slash.assert_called_once()
```
---
## 🔗 **Integration Testing**
### **Cross-Phase Workflows**
1. **End-to-End Job Execution**
- Client creates job → Agent matches → Escrow funded → Work completed → Payment released
2. **Consensus with Network**
- Validators discover peers → Form consensus → Propagate blocks → Handle partitions
3. **Economics with Agents**
- Agents earn rewards → Stake tokens → Reputation affects earnings → Economic incentives
4. **Contracts with All Layers**
- Escrow created → Network validates → Economics processes → Agents participate
### **Test Scenarios**
```python
@pytest.mark.asyncio
async def test_end_to_end_job_execution_workflow(self):
"""Test complete job execution workflow across all phases"""
# 1. Client creates escrow contract
success, _, contract_id = mock_escrow.create_contract(...)
# 2. Find suitable agent
agents = mock_agents.find_agents("text_generation")
# 3. Network communication
success, _, _ = mock_protocol.send_message(...)
# 4. Consensus validation
valid, _ = mock_consensus.validate_transaction(...)
# 5. Complete workflow
assert success is True
```
---
## 📊 **Test Reports**
### **HTML Coverage Report**
```bash
python -m pytest --cov=aitbc_chain --cov-report=html
# View: htmlcov/index.html
```
### **Performance Report**
```bash
python -m pytest test_performance_benchmarks.py -v --tb=short
# Output: Performance metrics and benchmark results
```
### **Security Report**
```bash
python -m pytest test_security_validation.py -v --tb=long
# Output: Security validation results and vulnerability assessment
```
---
## 🛠️ **Test Utilities**
### **Helper Functions**
```python
# Performance assertion
def assert_performance_metric(actual, expected, tolerance=0.1):
"""Assert performance metric within tolerance"""
lower_bound = expected * (1 - tolerance)
upper_bound = expected * (1 + tolerance)
assert lower_bound <= actual <= upper_bound
# Async condition waiting
async def async_wait_for_condition(condition, timeout=10.0):
"""Wait for async condition to be true"""
start_time = time.time()
while time.time() - start_time < timeout:
if condition():
return True
await asyncio.sleep(0.1)
raise AssertionError("Timeout waiting for condition")
# Test data generators
def generate_test_transactions(count=100):
"""Generate test transactions"""
return [create_test_transaction() for _ in range(count)]
```
### **Mock Decorators**
```python
@mock_integration_test
def test_cross_phase_functionality():
"""Integration test with mocked dependencies"""
pass
@mock_performance_test
def test_system_performance():
"""Performance test with benchmarking"""
pass
@mock_security_test
def test_attack_prevention():
"""Security test with attack simulation"""
pass
```
---
## 📝 **Writing New Tests**
### **Test Structure Template**
```python
class TestNewFeature:
"""Test new feature implementation"""
@pytest.fixture
def new_feature_instance(self):
"""Create test instance"""
return NewFeature()
@pytest.mark.asyncio
async def test_basic_functionality(self, new_feature_instance):
"""Test basic functionality"""
# Arrange
test_data = create_test_data()
# Act
result = await new_feature_instance.process(test_data)
# Assert
assert result is not None
assert result.success is True
@pytest.mark.integration
def test_integration_with_existing_system(self, new_feature_instance):
"""Test integration with existing system"""
# Integration test logic
pass
@pytest.mark.performance
def test_performance_requirements(self, new_feature_instance):
"""Test performance meets requirements"""
# Performance test logic
pass
```
### **Best Practices**
1. **Use descriptive test names**
2. **Arrange-Act-Assert pattern**
3. **Test both success and failure cases**
4. **Mock external dependencies**
5. **Use fixtures for shared setup**
6. **Add performance assertions**
7. **Include security edge cases**
8. **Document test purpose**
---
## 🚨 **Troubleshooting**
### **Common Issues**
#### **Import Errors**
```bash
# Add missing paths to sys.path
export PYTHONPATH="/opt/aitbc/apps/blockchain-node/src:$PYTHONPATH"
```
#### **Mock Mode Issues**
```bash
# Disable mock mode for integration tests
export AITBC_MOCK_MODE=false
python -m pytest test_phase_integration.py -v
```
#### **Performance Test Timeouts**
```bash
# Increase timeout for slow tests
python -m pytest test_performance_benchmarks.py -v --timeout=300
```
#### **Security Test Failures**
```bash
# Run security tests with verbose output
python -m pytest test_security_validation.py -v -s --tb=long
```
### **Debug Mode**
```bash
# Run with debug logging
export AITBC_LOG_LEVEL=DEBUG
python -m pytest test_mesh_network_transition.py::test_consensus_initialization -v -s
```
