Claude Code reads ANTHROPIC_DEFAULT_MODEL as its lowest-priority startup model (after --model, ANTHROPIC_MODEL and the settings `model` field). It is a plain model id, so behind a proxy a bare value is clamped to 200k exactly like the tier keys. Add it to EXTRA_EXTENDED_CONTEXT_MODEL_ENV_KEYS so --1m/--no-1m and the saved preference toggle it with the rest. The `--settings` launch overlay only carried the routing keys plus the five Anthropic tier keys. Claude Code applies the settings `env` block on top of the process environment, so a bare CLAUDE_CODE_SUBAGENT_MODEL or ANTHROPIC_DEFAULT_MODEL persisted on disk silently undid the resolved --1m result (and a saved [1m] undid --no-1m). Overlay the extended-context extra keys too. Verified with a stub Claude binary reading the overlay file: ccs claude --no-1m -> ANTHROPIC_DEFAULT_MODEL=claude-opus-5, CLAUDE_CODE_SUBAGENT_MODEL=claude-sonnet-5 ccs claude --1m -> both keys suffixed with [1m]
CCS Test Suite
Root TypeScript and JavaScript tests run with Bun's test runner. Native shell, PowerShell, Docker, and standalone probes cover contracts that need a real platform or process boundary.
Ownership
| Area | Path | Use for |
|---|---|---|
| Unit | unit/ |
Focused module and command behavior |
| Integration | integration/ |
Cross-module, process, proxy, auth, and web-server behavior |
| End to end | e2e/ |
Packaged CLI workflows |
| npm package | npm/ |
Installation, exports, and package behavior |
| Native | native/ |
Unix and Windows shell behavior |
| Docker | docker/ |
Compose and stable network/service contracts |
| Documentation | docs/ |
Repository documentation invariants |
| Shared support | shared/ |
Fixtures and helpers reused by suites |
| Mocks | mocks/ |
Bounded test doubles and fixtures |
Some source domains also keep focused tests in src/**/__tests__/. Follow the
nearest established pattern and avoid moving tests solely for taxonomy.
Commands
Commands are defined in ../package.json. Bucket membership
and execution live in
../scripts/run-test-bucket.js.
bun run test:fast # Fast Bun test bucket
bun run test:slow # Slow Bun test bucket
bun run test:all # All root non-e2e Bun test buckets
bun run test:unit # tests/unit
bun run test:npm # tests/npm
bun run test:native # Native Unix edge-case script
bun run test:e2e # tests/e2e with fail-fast and extended timeout
bun run test # Build, then test:all
For the normal contributor gate:
bun run format
bun run lint:fix
bun run validate
For the closest local equivalent to PR CI:
bun run validate:ci-parity
Dashboard tests use Vitest and are documented in
../ui/README.md.
Test Isolation
- Set
CCS_HOMEto a temporary directory. - Never read or modify a contributor's real
~/.ccs/or~/.claude/. - Use
getCcsDir()from../src/utils/config-manager.tsfor CCS paths. - Keep fixtures deterministic and free of credentials or private account data.
- Use real behavior at the boundary under test; do not weaken assertions to hide regressions.
Adding Coverage
- Add a focused unit test for isolated logic.
- Add integration coverage when behavior crosses modules, processes, HTTP, or persistence boundaries.
- Add e2e coverage when command routing or packaged CLI behavior is the contract.
- Add native or Docker coverage only when platform/runtime behavior cannot be represented faithfully in Bun tests.
- Run the smallest relevant command first, then broaden to the contributor or CI-parity gate when shared contracts changed.
