# Test Coverage Analysis

**Generated**: 2026-01-09 (pre-Phase 13 extraction)
**Status**: Historical — see note below.

> **⚠️ Historical document** — This coverage analysis was generated **before** the Phase 13 extraction (commit `0269e609`+) that moved all core graph logic from memory-mcp into the `@danielsimonjr/memoryjs` library. The numbers below describe the pre-extraction repository.
>
> **Current memory-mcp (v12.2.0):**
> - **Source files**: 5 TypeScript files in `src/` (entry point + 4 server-layer files)
> - **Test files**: 26 (`SKIP_BENCHMARKS=true npm test`)
> - **Tests**: 665 passing
> - **Coverage**: >92% statement coverage on the thin MCP wrapper
>
> Core-library coverage now lives in [`@danielsimonjr/memoryjs`](https://github.com/danielsimonjr/memoryjs). This file is preserved as a snapshot of the pre-extraction codebase for historical reference.

## Source Files Without Test Coverage

The following 2 source files are not directly imported by any test file:

### features/

- `src/features/index.ts` → Expected test: `tests/unit/features/index.test.ts`

### workers/

- `src/workers/index.ts` → Expected test: `tests/unit/workers/index.test.ts`
