test-runner

name

test-runner

description

Execute the appropriate test suite (unit, Gherkin, e2e, smoke) and return structured results. Use during Phase 3 (e2e test verification), Phase 4 (red baseline verification), Phase 5 (contract type compilation), Phase 6 (API/Web/integration slices), Phase 7 (smoke tests against deployment), and on resume (re-validate test state). Trigger when running tests, checking test status, or verifying test baselines.

Test Runner

Execute tests and return structured results for the orchestrator.

Test Commands

Type	Command
Unit (TypeScript)	cd src/api && npm test
Gherkin	npx cucumber-js
E2E	npx playwright test --config=e2e/playwright.config.ts
Smoke	npx playwright test --grep @smoke
All	npm run test:all

Steps

1. Verify Aspire environment (for Gherkin/e2e/smoke/all) — Before running integration tests, ensure the Aspire environment is running:
   • Use aspire describe --format Json (or the Aspire MCP list_resources tool) to check resource status
   • If resources are not healthy, run aspire start + aspire wait api --status healthy + aspire wait web --status healthy
   • If resources show errors, use aspire logs <resource> (or list_console_logs) to diagnose
2. Determine test type — Select the test suite based on current phase and task
3. Run tests — Execute the command, capture stdout and stderr
4. Parse results — Extract pass/fail counts, failure details, and test names
5. Detect flaky tests — If a test failed, re-run it once; if it passes on retry, flag as flaky
6. Diagnose failures with Aspire MCP — On test failure, use Aspire observability:
   • list_console_logs for resource stdout/stderr around failure time
   • list_structured_logs for OpenTelemetry log entries
   • list_traces to find the failing request's distributed trace
   • list_trace_structured_logs with the trace ID for full request lifecycle
7. Structure output — Format results for the orchestrator

Output Format

Type: unit | gherkin | e2e | smoke | all
Pass: <count>
Fail: <count>
Flaky: <count>
Verdict: GREEN | RED | FLAKY

Failed tests:
- <test name>: <error message>

Aspire MCP Debugging Workflow

When tests fail against the Aspire environment:

1. list_resources              → Are all resources Running + Healthy?
2. list_console_logs(resource) → Any errors in stdout/stderr?
3. list_traces(resource)       → Find the trace for the failing request
4. list_trace_structured_logs  → Full trace lifecycle with all spans
5. execute_resource_command    → Restart a resource if stuck

Edge Cases

• Test runner itself fails (not assertions) → report as infrastructure failure
• Aspire resources unhealthy → restart via aspire start (auto-stops previous)
• Tests exceed 5 minutes → check for hung processes
• Always capture both stdout and stderr
