+```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
+```

+
+### **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

+    """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"""

+
+## 📝 **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**
