Maintains alignment between tests and source code by detecting orphaned tests, missing coverage, and implementation coupling.
Use after major refactors to ensure tests reflect current code structure.

Orphaned test detection identifies tests written for code that no longer exists or has been renamed. Run test-sync after major refactors to find tests referencing deleted functions, classes, or modules, then remove or update them to maintain suite health and prevent misleading coverage reports.
Missing coverage detection scans your source code to identify functions, classes, and modules without corresponding tests. test-sync maps source code to test suites and flags gaps, helping you prioritize what to test and ensuring critical paths have traceability before deployment.
Implementation-coupled tests fail when internal code changes even if external behavior stays the same. test-sync flags tests that depend on specific implementation details, helping you refactor them to test behavior instead and making your suite more resilient to refactors.
Run test-sync after major refactors, during routine health audits, or when tests fail for deleted or renamed code. It generates a structured report with risk indicators and remediation steps, guiding cleanup, coverage rebaselining, and validation of test-to-code traceability.
test-sync analyzes test-to-source mappings and structural alignment independent of framework specifics. It works across codebases using different test frameworks and languages by examining test names, imports, and code references to detect orphaned tests and coverage gaps.
test-sync outputs a structured report containing test-to-code mappings, risk indicators for orphaned and missing tests, implementation-coupling flags, and actionable remediation recommendations to guide cleanup and coverage decisions.
