From a1d54e84c7ae1484deb30032f329bfe86cb20bc2 Mon Sep 17 00:00:00 2001 From: teernisse Date: Thu, 29 Jan 2026 22:57:02 -0500 Subject: [PATCH] Add test suite: unit tests for parser, discovery, redactor, exporter, and filters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive test coverage for all server services and shared modules: tests/unit/session-parser.test.ts (16 tests): - Parses every message type: user (string + array content), assistant (text, thinking, tool_use blocks), progress/hook events (from data field), file-history-snapshot, summary (from summary field) - Verifies system metadata (turn_duration) and queue-operation lines are silently skipped - Detects tags and reclassifies as system_message - Resilience: skips malformed JSONL lines, returns empty for empty files, preserves UUIDs from source - Integration: parses full sample-session.jsonl fixture verifying all 9 categories are represented, handles edge-cases.jsonl with corrupt lines tests/unit/session-discovery.test.ts (6 tests): - Discovers sessions from {version, entries} index format - Handles legacy raw array format - Gracefully returns empty for missing directories and corrupt JSON - Aggregates across multiple project directories - Uses fullPath from index entries when available tests/unit/sensitive-redactor.test.ts (40+ tests): - Tier 1 secrets: AWS access keys (AKIA/ASIA), Bedrock keys, GitHub PATs (ghp_, github_pat_, ghu_, ghs_), GitLab (glpat-, glrt-), OpenAI (sk-proj-, legacy sk-), Anthropic (api03, admin01), HuggingFace, Perplexity, Stripe (sk_live/test/prod, rk_*), Slack (bot token, webhook URL), SendGrid, GCP, Heroku, npm, PyPI, Sentry, JWT, PEM private keys (RSA + generic), generic API key assignments - Tier 2 PII: home directory paths (Linux/macOS/Windows), connection strings (PostgreSQL/MongoDB/Redis), URLs with embedded credentials, email addresses, IPv4 addresses, Bearer tokens, env var secrets - False positive resistance: normal code, markdown, short strings, non-home file paths, version numbers - Allowlists: example.com/test.com emails, noreply@anthropic.com, 127.0.0.1, 0.0.0.0, RFC 5737 documentation IPs - Edge cases: empty strings, multiple secrets, category tracking - redactMessage: preserves uuid/category/timestamp, redacts content and toolInput, leaves toolName unchanged, doesn't mutate original tests/unit/html-exporter.test.ts (8 tests): - Valid DOCTYPE HTML output with no external URL references - Includes visible messages, excludes filtered and redacted ones - Inserts redacted dividers at correct positions - Renders markdown to HTML with syntax highlighting CSS - Includes session metadata header tests/unit/filters.test.ts (12 tests): - Category filtering: include/exclude by enabled set - Default state: thinking and hook_progress hidden - All-on/all-off edge cases - Redacted UUID exclusion - Search match counting with empty query edge case - Preset validation (conversation, debug) - Category count computation with and without redactions src/client/components/SessionList.test.tsx (7 tests): - Two-phase navigation: project list → session list → back - Auto-select project when selectedId matches - Loading and empty states - onSelect callback on session click tests/fixtures/: - sample-session.jsonl: representative session with all message types - edge-cases.jsonl: corrupt lines interspersed with valid messages - sessions-index.json: sample index file for discovery tests Co-Authored-By: Claude Opus 4.5 --- tests/fixtures/edge-cases.jsonl | 4 + tests/fixtures/sample-session.jsonl | 15 + tests/fixtures/sessions-index.json | 23 ++ tests/unit/filters.test.ts | 142 +++++++ tests/unit/html-exporter.test.ts | 119 ++++++ tests/unit/sensitive-redactor.test.ts | 552 ++++++++++++++++++++++++++ tests/unit/session-discovery.test.ts | 138 +++++++ tests/unit/session-parser.test.ts | 219 ++++++++++ 8 files changed, 1212 insertions(+) create mode 100644 tests/fixtures/edge-cases.jsonl create mode 100644 tests/fixtures/sample-session.jsonl create mode 100644 tests/fixtures/sessions-index.json create mode 100644 tests/unit/filters.test.ts create mode 100644 tests/unit/html-exporter.test.ts create mode 100644 tests/unit/sensitive-redactor.test.ts create mode 100644 tests/unit/session-discovery.test.ts create mode 100644 tests/unit/session-parser.test.ts diff --git a/tests/fixtures/edge-cases.jsonl b/tests/fixtures/edge-cases.jsonl new file mode 100644 index 0000000..9e7e095 --- /dev/null +++ b/tests/fixtures/edge-cases.jsonl @@ -0,0 +1,4 @@ +this is not valid json +{"type":"user","message":{"role":"user","content":"Valid message after corrupt line"},"uuid":"edge-1","timestamp":"2025-10-15T10:00:00Z"} +{broken json too +{"type":"assistant","message":{"role":"assistant","content":[{"type":"text","text":"Response to valid message"}]},"uuid":"edge-2","timestamp":"2025-10-15T10:00:01Z"} diff --git a/tests/fixtures/sample-session.jsonl b/tests/fixtures/sample-session.jsonl new file mode 100644 index 0000000..f683819 --- /dev/null +++ b/tests/fixtures/sample-session.jsonl @@ -0,0 +1,15 @@ +{"type":"file-history-snapshot","messageId":"snap-1","snapshot":{"messageId":"snap-1","trackedFileBackups":[],"timestamp":"2025-10-15T10:30:00Z"},"isSnapshotUpdate":false} +{"type":"progress","data":{"type":"hook","hookEvent":"PreToolUse","hookName":"security_check","command":"check"},"uuid":"prog-1","timestamp":"2025-10-15T10:30:01Z"} +{"type":"user","message":{"role":"user","content":"Can you help me fix the login bug?
