# tests/test-utils/session-id-generator.ts @source-hash: 08c0b8adea108bbd @generated: 2026-02-10T00:41:55Z ## Purpose Test utility module for generating unique session IDs that help track test execution and identify resource/promise leaks in test environments. ## Key Functions ### `getTestSessionId(testName?: string)` (L11-30) - **Purpose**: Generates unique session IDs for test identification - **Input**: Optional test name string - **Output**: Formatted session ID string - **Logic**: - Fallback mode (L12-15): Returns `session-unknown-{timestamp}-{random}` when no test name provided - Name cleaning (L19-23): Sanitizes test name by removing special chars, collapsing dashes, trimming, and limiting to 30 chars - ID composition (L26-29): Combines `session-{cleanName}-{timestamp}-{random}` format - **Uniqueness**: Uses `Date.now()` timestamp + 3-char random base36 suffix ### `getTestNameFromSessionId(sessionId: string)` (L37-43) - **Purpose**: Reverse-parses session IDs to extract original test names for debugging - **Input**: Session ID string to parse - **Output**: Test name string or null if invalid format - **Logic**: Uses regex `/^session-([^-]+(?:-[^-]+)*)-\d+-[a-z0-9]+$/` to match expected format and converts dashes back to spaces ## Architecture Patterns - **Bidirectional encoding**: Clean encoding with reversible parsing - **Defensive design**: Graceful fallback for missing test names - **Collision avoidance**: Multi-factor uniqueness (timestamp + randomness) ## Dependencies - Standard JavaScript Date and Math APIs only - No external dependencies ## Use Case Primarily for test debugging and resource leak detection by providing traceable identifiers that can be correlated back to specific test cases.
