- findFiles with both maxAge AND recursive combined (option interaction test)
- parseSessionMetadata truncates item text at embedded ### due to lazy regex
- cleanupAliases callback returning 0 (falsy non-boolean) removes alias via !0 coercion
Total tests: 860
- replaceInFile returns true even when pattern doesn't match (silent rewrite)
- grepFile treats CR-only (\r) file as single line (splits on \n only)
- writeSessionContent(null) returns false (TypeError caught by try/catch)
- getSessionById(null) throws TypeError at line 297 (null.length)
- parseSessionFilename(null) throws TypeError at line 30 (null.match())
- findFiles with maxAge: -1 deterministically excludes all files
- detectFromPackageJson with scoped package name (@scope/pkg@version)
returns null because split('@')[0] yields empty string
- getPackageManager skips empty string CLAUDE_PACKAGE_MANAGER via
falsy short-circuit (distinct from unknown PM name test)
- session-end buildSummarySection includes Tools Used but omits
Files Modified when transcript has only Read/Grep tools
Total tests: 842
- getSessionStats: drive letter without slash (Z:nosession.tmp) treated as content
- countInFile: case-insensitive regex with g flag auto-appended (/foo/i → /foo/ig)
- countInFile: case-insensitive regex with g flag preserved (/foo/gi stays /foo/gi)
- Test countInFile returns 0 for object pattern type (non-string non-RegExp)
- Test getSessionStats treats Windows UNC path as content (not file path)
- Test detectFromPackageJson returns null for empty string packageManager field
Total tests: 836
- Test getCommandPattern('') produces valid regex for empty action string
- Test detectFromPackageJson returns null for whitespace-only packageManager
- Test getSessionStats treats mixed Windows path separators as file path
Total tests: 833
- Test readStdinJson timeout path when stdin never closes (resolves with {})
- Test readStdinJson timeout path with partial invalid JSON (catch resolves with {})
- Test saveAliases backup restore double failure (inner restoreErr catch at line 135)
Total tests: 830
- replaceInFile with empty replacement string verifies text deletion works
- parseSessionMetadata asserts date/started/lastUpdated are null when fields absent
- countInFile with valid file but non-matching pattern returns 0
Total: 824 tests
- loadAliases resets to defaults when aliases field is a truthy non-object (string)
- detectFromPackageJson returns null for empty (0-byte) package.json
- evaluate-session uses learned_skills_path config override with ~ expansion
Round 80: Three previously untested conditional branches:
- session-end.js: entry.message?.role === 'user' third OR condition
(fires when type is not 'user' but message.role is)
- package-manager.js: getExecCommand with truthy non-string args
(typeof check short-circuits, value still appended via ternary)
- validate-hooks.js: legacy array format parsing path (lines 115-135)
with 'Hook N' error labels instead of 'EventType[N]'
- evaluate-session: main().catch when HOME is non-directory (ENOTDIR)
- suggest-compact: main().catch double-failure when TMPDIR is non-directory
- validate-hooks: invalid JSON in hooks.json triggers error exit
Total tests: 831 → 834
- session-manager: deleteSession returns false when dir is read-only (EACCES)
- pre-compact: main().catch handler when HOME is non-directory (ENOTDIR)
- session-end: main().catch handler when HOME is non-directory (ENOTDIR)
Total tests: 828 → 831
- setup-package-manager: setGlobal catch when HOME is non-directory (ENOTDIR)
- setup-package-manager: setProject catch when CWD is read-only (EACCES)
- session-start: main().catch handler when ensureDir throws (exit 0, don't block)
Total tests: 825 → 828
Round 73: Add 3 tests for genuine untested code paths:
- session-aliases cleanupAliases returns failure when save blocked after removing aliases
- session-aliases setAlias returns failure when save blocked on new alias creation
- validate-commands silently skips broken symlinks in skill directory scanning
- session-end.js: entry.name/entry.input fallback in direct tool_use entries
- validate-commands.js: "would create:" regex alternation skip line
- session-aliases.js: updateAliasTitle save failure with read-only dir
- session-manager.js: getSessionById with date-only string exercises the
noIdMatch path for old-format sessions (2026-02-10 → 2026-02-10-session.tmp)
- session-end.js: extract user messages from role-only JSONL format
({"role":"user",...} without type field) exercises line 48 fallback
- session-end.js: nonexistent transcript_path triggers "Transcript not found"
log path (lines 153-155), creates session with blank template
Total: 803 tests, all passing
- evaluate-session.js: verify regex whitespace tolerance around colon
matches "type" : "user" (with spaces), not just compact JSON
- validate-rules.js: empty directory with no .md files yields Validated 0
- validate-skills.js: directory with only files, no subdirectories yields
Validated 0
Total: 800 tests, all passing
- suggest-compact: 'default' session ID fallback when CLAUDE_SESSION_ID empty
- session-aliases: loadAliases backfills missing version and metadata fields
- post-edit-typecheck: valid JSON without tool_input passes through unchanged
Total: 797 tests, all passing
- setup-package-manager.test.js: --global npm writes config and exits 0
- setup-package-manager.test.js: bare PM name sets global preference
- setup-package-manager.test.js: --detect with env var shows source 'environment'
791 tests total, all passing.
- utils.test.js: replaceInFile returns false on read-only file (catch block)
- session-manager.test.js: getAllSessions returns empty when sessions dir missing
- package-manager.test.js: getPackageManager falls through corrupted global config to npm default
788 tests total, all passing.
- getAllSessions search matches only shortId, not title/content
- getSessionPath returns absolute path with correct directory structure
- analysisResults handles zero values for all data fields without crash
Round 53: Adds 3 hook tests — validates evaluate-session.js
falls back to CLAUDE_TRANSCRIPT_PATH env var when stdin JSON
is invalid, post-edit-console-warn.js truncates output to max
5 matches, and post-edit-format.js passes through data when
the target .tsx file doesn't exist.
