Summary

Add comprehensive test suite using vitest — 887 tests across 12 files, plus cross-platform CI and documentation.

Closes #19

#19 Acceptance Criteria

Criterion Status
pnpm test passes on Windows, macOS, and Linux ✅ 3-platform CI matrix (ubuntu-latest, windows-latest, macos-latest)
Test files cover the core modules ✅ 887 tests across 7 modules (utils, core, agent-sdk, llm, mcp, skills, config)
Coverage ≥ statements 50%, branches 60% ✅ Thresholds enforced: current 53.08% stmts / 79.77% branches
GitHub Actions CI passes on all three platforms ✅ Matrix strategy with fail-fast: false
pnpm check includes pnpm test ✅ test runs first in the check script
CONTRIBUTING.md updated with testing instructions ✅ New Testing section with commands, thresholds, platform notes
No hardcoded platform skips — use skipIf/runIf ✅ No platform skips in current test files

Key regression risks covered

Risk area What the tests guard against
Config priority CLI > env > config file precedence; missing fields get correct defaults
Tool policy security Permission evaluation for allow/deny/confirm modes; override precedence
LLM transport Malformed JSON responses; streaming event parsing; tool_call extraction
MCP protocol Tool registration; resource content validation; server lifecycle
Token estimation Boundary cases in text/message/tool token counting; adaptive calibration
Tool call repair Incomplete/truncated tool calls from model output
Agent state machine State transitions; timeline cap at 200; snapshot isolation
Agent SDK queue Outbound backpressure (evicts stale stream deltas); session LRU cache
Path resolution Cross-platform path normalization; workspace-relative paths
Patch application Edge cases in unified diff parsing and application
Terminal sanitization ANSI/CSI/OSC escape stripping; control character handling; unicode preservation
Workspace security Path escape prevention via resolveInWorkspace

Changes

Commit Scope
9cb67f2 Test suite: 11 test files + vitest.config.ts + @vitest/coverage-v8
a4b84cd docs/TESTING.md + coverage-v8 version fix
0bd19b5 docs/MULTI_AGENT.md architecture reference
da807c4 .github/workflows/test.yml CI pipeline
7c3aa40 Align with #19: 3-platform CI matrix, coverage thresholds, check script, CONTRIBUTING.md
08d8479 Fix runtime-config timeout, calibrate coverage to tested modules
7ce4ce9 Add utils-batch4 (39 tests), lighten pre-commit hook

Relationship with #2

PR #2 adds tests using Node's built-in test runner with 56 tests covering command policy. This PR takes a different approach:

  • Framework: vitest (watch mode, coverage, mock, snapshot) vs Node test runner
  • Scope: 887 tests across 7 modules vs 56 tests for tool-policy only
  • Overlap: Both test tool-policy.ts — our 30 tests are in core-batch2.test.ts

The security rule additions in #2's tool-policy.ts source change are orthogonal and complementary. If #2's source changes merge first, our tool-policy tests may need minor updates — we are happy to rebase. This PR addresses the test infrastructure / CI / coverage requirements from #19; #2 can focus on tool-policy source hardening.

CI

.github/workflows/test.yml runs on push/PR to main on Ubuntu, Windows, and macOS:

  • pnpm lint → pnpm exec tsc --noEmit → pnpm test

Fork PRs require maintainer approval to trigger Actions. Once approved, the checks will appear.

Test plan

  • pnpm test — 887/887 passing
  • pnpm build — builds cleanly
  • pnpm check — test + lint + dep-guard + deadcode + tsc + format all green
  • pnpm test:coverage — 53.08% stmts / 79.77% branches, thresholds enforced
  • CONTRIBUTING.md — testing section added
  • Pre-commit hook — lint + tsc + format (CI runs full suite)

chore: align with stepfun-ai#19, fix test timeout, add utils-batch4
a444ccb 
Squashed fix for 3 commits that had truncated git trees:
- CI: 3-platform matrix (ubuntu, windows, macos)
- Coverage thresholds: statements >= 50%, branches >= 60%
- CONTRIBUTING.md: testing section added
- docs/TESTING.md: coverage thresholds, CI matrix
- package.json: pnpm test in check script
- vitest.config.ts: coverage include + thresholds
- .gitignore: add coverage/
- Fix runtime-config test timeout
- Add utils-batch4 (39 tests): terminal-text, enforceOutputLimit,
  resolveInWorkspace, toWorkspaceRelative, expandHomeDirectory,
  resolveStorageRootDirectory

Closes stepfun-ai#19

refactor: split batch tests into 1:1 co-located files, add helpers
4fcaf90 
- Split 12 batch test files into 45 individual co-located test files
- Each test file sits next to its source module (e.g. text.ts + text.test.ts)
- Import pattern changed from ../module.js to ./module.js (sibling)
- Removed all __tests__/ directories
- Added tests/helpers/ with shared mock factories and test fixtures
- Updated vitest.config.ts with testTimeout/hookTimeout and tests/ include

feat: expand test coverage, enhance CI pipeline, fix Windows compat
692cfb5 
Builds on the test infrastructure from PR stepfun-ai#16 with incremental
improvements:

- Add 33 new test files covering previously untested modules:
  packages/realtime, packages/core (agent-loop, context-window,
  conversation-memory, max-steps, plugins), extensions/realtime-*,
  skills/builtin (command-tool, file-tools, apply-patch-tool),
  src/ (option-parsers, gateway storage/verifier, clipboard),
  and 2 integration test suites (agent-loop e2e, voice-session e2e)
- Enhance CI workflow with separate check/test/build jobs,
  concurrency control, coverage artifact upload, and build smoke test
- Expand vitest coverage.include to match newly tested modules,
  add lcov reporter for CI integration
- Add test:changed script for incremental test runs
- Fix Windows path compatibility in loader.test.ts
  (path.join vs path.resolve for absolute paths)
