token-usage.ts: 55% → 95% statements
- Adds tests for parseClaudeCodeJsonl (0% → fully covered): sidechain skip,
synthetic model skip, missing usage, zero-total skip, malformed JSON lines,
multi-line files
- Adds tests for getTokenUsage source filtering (copilot-cli / claude-code / all)
using temp-dir fixtures + vi.mock("os")
- Adds weekly/monthly bucket and per-model breakdown tests to aggregate suite
vscode-sessions.ts: 45% → 92% statements
- New vscode-sessions-api.test.ts tests the public API (listVSCodeSessions,
getVSCodeSession, isVSCodeSession, getVSCodeAnalytics) with a configurable
better-sqlite3 mock and temp-dir session JSON fixtures
- Key fix: Vitest 4 requires regular functions (not arrow functions) in
mockImplementation when the mock is called with `new`
