# tests/unit/proxy/orphan-check.test.ts @source-hash: d09512c453933f03 @generated: 2026-02-10T00:41:30Z ## Purpose Unit test suite for orphan process detection utilities in the proxy module, ensuring proper behavior of orphan exit conditions based on parent process ID and container environment. ## Key Test Functions ### `shouldExitAsOrphan` Tests (L5-17) Tests the core orphan detection logic with direct parameters: - **Init process outside containers** (L6-8): Verifies exit when parent PID is 1 and not in container - **Container namespace protection** (L10-12): Ensures no exit when running inside containers (PID 1 + container flag) - **Non-init parent handling** (L14-16): Confirms no exit when parent is not init process (PID 42) ### `shouldExitAsOrphanFromEnv` Tests (L19-42) Tests environment-aware wrapper function: - **Environment flag derivation** (L20-27): Validates `MCP_CONTAINER` env var interpretation (`'true'`/`'false'`) - **Process.env fallback** (L29-41): Tests default behavior when no env argument provided, with proper cleanup ## Dependencies - **Vitest** (L1): Testing framework - **Source module** (L2): `../../../src/proxy/utils/orphan-check.js` - imports `shouldExitAsOrphan` and `shouldExitAsOrphanFromEnv` ## Test Patterns - Direct boolean assertions for exit conditions - Environment variable manipulation with cleanup (L30-40) - Container vs non-container scenario coverage - PID 1 (init process) as primary test case for orphan detection
