/test - Testing Workflow

Run comprehensive test suite with parallel execution.

When to Use

• "Run all tests"
• "Test the feature"
• "Verify everything works"
• "Full test suite"
• Before releases or merges
• After major changes

Agent Sequence

| Agent | Role | Execution

---|---|---|---
1 | arbiter | Unit tests, type checks, linting | Parallel
1 | arbiter | Integration tests | Parallel
2 | atlas | E2E/acceptance tests | After 1 passes

Why This Order?

1. Fast feedback : Unit tests fail fast
2. Parallel efficiency : No dependency between unit and integration
3. E2E gating : Only run slow E2E tests if faster tests pass

Execution

Phase 0: Pre-flight Diagnostics (NEW)

Before running tests, check for type errors - they often cause test failures:

tldr diagnostics . --project --format text 2>/dev/null | grep "^E " | head -10

Why diagnostics first?

• Type check is instant (~1s), tests take longer
• Diagnostics show ROOT CAUSE, tests show symptoms
• "Expected int, got str" is clearer than "AttributeError at line 50"
• Catches errors in untested code paths

If errors found: Fix them BEFORE running tests. Type errors usually mean tests will fail anyway.

If clean: Proceed to Phase 1.

Phase 0.5: Change Impact (Optional)

For large test suites, find only affected tests:

tldr change-impact --session
# or for explicit files:
tldr change-impact src/changed_file.py

This returns which tests to run based on what changed. Skip this for small projects or when you want full coverage.

Phase 1: Parallel Tests

# Run both in parallel
Task(
  subagent_type="arbiter",
  prompt="""
  Run unit tests for: [SCOPE]

  Include:
  - Unit tests
  - Type checking
  - Linting

  Report: Pass/fail count, failures detail
  """,
  run_in_background=true
)

Task(
  subagent_type="arbiter",
  prompt="""
  Run integration tests for: [SCOPE]

  Include:
  - Integration tests
  - API tests
  - Database tests

  Report: Pass/fail count, failures detail
  """,
  run_in_background=true
)

# Wait for both
[Check TaskOutput for both]

Phase 2: E2E Tests (If Phase 1 Passes)

Task(
  subagent_type="atlas",
  prompt="""
  Run E2E tests for: [SCOPE]

  Include:
  - End-to-end flows
  - Acceptance tests
  - UI tests if applicable

  Report: Pass/fail count, screenshots on failure
  """
)

Test Scopes

Full Suite

User: /test
→ All unit + integration + E2E tests

Feature Scope

User: /test authentication
→ Only auth-related tests

Quick Check

User: /test --quick
→ Only unit tests (skip integration and E2E)

Example

User: /test the new payment feature

Claude: Starting /test workflow for payment feature...

Phase 0: Pre-flight diagnostics...
$ tldr diagnostics . --project --format text | grep "^E "
(no type errors found)

Phase 1: Running parallel tests...
┌─────────────────────────────────────────┐
│ arbiter: Running unit tests...          │
│ arbiter: Running integration tests...   │
└─────────────────────────────────────────┘

arbiter: ✅ 45/45 unit tests passing
arbiter: ✅ 12/12 integration tests passing

Phase 2: Running E2E tests...
atlas: ✅ 8/8 E2E tests passing

Test Summary:
┌─────────────┬─────────┬────────┐
│ Type        │ Passed  │ Failed │
├─────────────┼─────────┼────────┤
│ Unit        │ 45      │ 0      │
│ Integration │ 12      │ 0      │
│ E2E         │ 8       │ 0      │
├─────────────┼─────────┼────────┤
│ TOTAL       │ 65      │ 0      │
└─────────────┴─────────┴────────┘

All tests passing! ✅

Example with Type Errors

User: /test

Claude: Starting /test workflow...

Phase 0: Pre-flight diagnostics...
$ tldr diagnostics . --project --format text | grep "^E "
E src/payment.py:45:12: Argument of type 'str' not assignable to 'int'
E src/refund.py:23:8: Return type 'None' not assignable to 'float'

Found 2 type errors. Fixing before running tests...

[Claude fixes the type errors]

Re-running diagnostics... clean.

Phase 1: Running parallel tests...

Failure Handling

If Phase 1 fails:

arbiter: ❌ 43/45 tests passing

2 failures:
- test_payment_validation: expected 'invalid' got 'valid'
- test_refund_calculation: off by $0.01

Stopping workflow. Fix failures before running E2E tests.

Flags

• --quick: Unit tests only
• --no-e2e: Skip E2E tests
• --coverage: Include coverage report
• --watch: Re-run on file changes
