Establishes permanent verification system to monitor test suite completeness and integrity with SHA256 function body hashing. This foundational infrastructure prevents test loss during refactoring and detects even subtle implementation changes.

What's Added

  • testing/scale_olm_test.py - Meta-tests that verify test suite integrity with hash-based checking
  • testing/test_functions_manifest.txt - Manifest of all 244 unique test functions with SHA256 hashes
  • scripts/regenerate_manifest.py - Script to update manifest when tests change

Enhanced Verification Features

  1. Hash-Based Change Detection - SHA256 hashes detect function implementation changes
  2. Manifest Currency Check - Ensures manifest matches current test functions and their hashes
  3. Duplicate Detection - Identifies duplicate function names across files (14 duplicates resolved)
  4. Baseline Protection - Prevents accidental loss of large numbers of tests
  5. Implementation Stability - Informational reporting of function body changes

Current State

  • Total unique functions: 244 (increased from 224 after deduplication)
  • Hash format: 2eb0dd355f834fe8:test_gridgradient_basic
  • Duplicate functions: Zero (all 14 previous duplicates resolved with descriptive suffixes)
  • All verification tests: ✅ Passing

Deduplication Work

Systematically resolved 14 duplicate test function names:

  • Advanced tests: _advanced suffix
  • Enhanced tests: _enhanced suffix
  • Module-specific: Module suffix (e.g., _report, _run, _generate_states)
  • Cross-module: Context suffix (e.g., _check vs _core)

Usage

# Run all verification tests
python -m pytest testing/scale_olm_test.py -v

# Update manifest after legitimate changes
python scripts/regenerate_manifest.py

# Check for implementation changes
python -m pytest testing/scale_olm_test.py::TestSuiteIntegrity::test_implementation_stability -v

Foolproof Detection

The hash-based system catches:
✅ Missing/extra functions
✅ Function renames
✅ Implementation changes (even single comments)
✅ Duplicate function names
✅ Mass test loss scenarios

Tested live: Successfully detected hash change from 2eb0dd355f834fe8 to 8508c041779b6c74 when single comment was added to test function.

This creates the foundation for confident test suite refactoring with guaranteed zero test loss verification.

- Add scale_olm_test.py with meta-tests for test suite integrity
- Include test_functions_manifest.txt with current 224 unique test functions
- Add scripts/regenerate_manifest.py for updating manifest
- Detect duplicate function names across files (14 found in current codebase)
- Verify manifest stays current with actual test functions
- Protect against accidental test loss with baseline count verification

This establishes permanent monitoring of test suite completeness.

@olm-bot you said there were duplicate test names. Let's rename those so we don't have duplicates

- Rename 14 duplicate test function names with descriptive suffixes
- Advanced test files get _advanced suffix (e.g., test_default_params_advanced)
- Enhanced test files get _enhanced suffix (e.g., test_schema_gridgradient_enhanced)
- Module-specific tests get module suffix (e.g., test_module_exports_report)
- Cross-module duplicates get context suffix (e.g., test_duplicate_degenerate_axis_value_check)

This resolves all duplicate function names that could cause test discovery issues.
Test function count increased from 224 to 243 unique functions.
All verification tests now pass with zero duplicates detected.
- Add SHA256 hashing of test function bodies for comprehensive change detection
- Manifest format now: hash:function_name (e.g., 2eb0dd355f834fe8:test_gridgradient_basic)
- Detect function additions, removals, renames, AND implementation changes
- New test_implementation_stability() provides informational hash change reports
- Enhanced test_manifest_is_current() fails on any hash mismatches
- Updated regenerate_manifest.py to use hash-based format

This creates a foolproof verification system that catches:
✅ Missing/extra functions
✅ Duplicate function names
✅ Function implementation changes
✅ Accidental test modifications during refactoring

Hash-based verification tested and working - detects even single comment changes.
