E2E Harness Operations

This document defines deterministic execution and cleanup for the tiered E2E harness.

Flow lifecycle

All flow scenarios follow:

1. provision
2. execute
3. poll
4. verify
5. cleanup (always runs in finally)

Implementation lives under tests/e2e/flows/, tests/e2e/provisioners/, and tests/e2e/verifiers/.

Tier commands

• Fast required: python -m pytest -q -m "tier_fast and not quarantined" --maxfail=1 --no-cov
• Heavy optional: python -m pytest -q -m "tier_heavy and not tier_external" --maxfail=1 --durations=25
• External nightly/release: python -m pytest -q -m "tier_external and cleanup_required" --maxfail=1 --durations=50

Environment model

Common:

• TESTO_E2E_RUN_ID (optional; auto-generated if not set)
• TESTO_E2E_KEEP_ON_FAIL (default false)
• TESTO_E2E_MAX_CLEANUP_ATTEMPTS (default 3)
• TESTO_E2E_EXTERNAL_DRY_RUN (true by default; set false in external CI gates)

GitHub external:

• TESTO_E2E_GITHUB_TOKEN
• TESTO_E2E_GITHUB_OWNER

GitLab external:

• TESTO_E2E_GITLAB_TOKEN
• TESTO_E2E_GITLAB_GROUP_ID
• TESTO_E2E_GITLAB_BASE_URL (optional, defaults to https://gitlab.com/api/v4)

Isolation and naming

• Ephemeral resources are named using testo-e2e-<run-id>-<provider>-<scenario>.
• Artifacts are written under .artifacts/e2e/<run-id>/.
• External CI jobs use external-e2e concurrency/resource locking.

Cleanup guarantees

• Every scenario writes cleanup records through cleanup_ledger.
• Session finalizer emits .artifacts/e2e/<run-id>/cleanup-ledger.json.
• External gates fail if cleanup audit detects any cleanup_failed record.

Diagnostics artifacts

On failed heavy/external runs, upload:

• logs (*.log)
• summary JSON (*summary*.json)
• API responses (*api*.json)
• screenshots (*.png, if UI scenarios are enabled)

Security and redaction

• Provider tokens must be injected via masked CI secrets/variables only.
• Do not print or serialize tokens into logs/artifacts.
• Keep provider API logic inside tests/e2e/provisioners/ adapters.
