+### Multiple Solution Classes Pattern
+
+When implementing multiple approaches (e.g., Solution, SolutionMath), use parametrized testing:
+
+```python
+@pytest.mark.parametrize("solution_class", [Solution, SolutionMath])
+@pytest.mark.parametrize("input_params, expected", test_cases)
+def test_method(self, solution_class, input_params, expected):
+    result = run_helper(solution_class, *input_params)
+    assert_helper(result, expected)
+```
+
+This pattern tests all solution approaches with the same test cases, ensuring consistency across implementations.

+**Process Name**: Test Reproducibility Verification
+
+**When to Use**:
+
+- CI test failures in reproducibility checks
+- Inconsistent test results between environments
+- Missing edge cases causing coverage gaps
+- Need to ensure 100% code coverage
+
 ## Success Criteria
 
 - All tests pass with enhanced test cases
 - Minimum 12 comprehensive test cases per problem
 - Original solution code preserved
 - **Enhanced test cases in final test_solution.py**
 - JSON template updated for future regeneration
+- **100% code coverage including edge cases**
