Testing Infrastructure Architecture Review

A deliberate, checkpoint-driven loop for evaluating and refactoring testing infrastructure when the current setup shows signs of fragility, slowness, or coverage gaps. Each change is reviewable, verifiable, and reversible.

Prompts capture what to ask. Playbooks capture repeatable methods. Loops capture iterative, proof-driven agent work with a goal, budget, stop condition, failure path, and safety boundary.

TRIGGER

Run when test suites show sustained flakiness, runtime degradation, coverage gaps, or when onboarding a new major system under test.

GOAL

Testing infrastructure is fast, deterministic, well-instrumented, and aligned with current production architecture. Satisfaction criteria are met and measurable.

STOP CONDITION

Stop when all satisfaction criteria are met, or two consecutive iterations show zero metric improvement, or a hard blocker requires operator escalation.

ITERATION

Action / Observe / Evaluate

Snapshot current metrics, make one reviewable infrastructure change, live-test affected paths, run independent review, commit checkpoint, update progress file with decisions and blockers.

VERIFY / PROOF

Evidence Gate

Affected tests pass locally and in CI. Metric improvement is documented (duration, flakiness, coverage). A second pair of eyes reviewed the diff.

STATE / MEMORY

Memory Contract

Read the last architecture review log and current CI dashboard. Write updated metrics, checkpoint commits, blocker status, and revised satisfaction criteria if changed.

MODELS

Not specified

BUDGET

Three iterations or 90 minutes, whichever comes first.

FAILURE HANDLING

No-Progress And Unsafe States

Revert breaking changes immediately and log failure mode. For inconclusive results, increase test sample or split change smaller. Escalate to operator if goal ambiguity or budget limits block progress.

SAFETY CONSTRAINTS

Boundary Conditions

Never disable tests to make the suite pass. Never commit credentials, internal URLs, or production data in test code. Always preserve rollback commits.

EXAMPLE OUTPUT

Expected Public Result

Structured report with: before/after metrics, checkpoint commit hashes, satisfaction criteria checklist, blocker log, and recommended next review date.

INSTRUCTIONS

Loop Method

Use this loop when your test suite, E2E pipeline, or agent tooling shows cracks: flaky tests, slow runs, unclear failure signals, missing coverage, or drift between test code and production behavior.

**Pre-flight — Define Satisfaction Criteria**
Before touching any code, write down:
- The architectural target (e.g., 'All E2E tests run in under 5 minutes with deterministic selectors')
- Hard constraints (budget, tooling limits, CI environment)
- Current risks ranked by severity (flakiness, blind spots, maintenance burden)
- Definition of done (specific, measurable — not 'better' or 'cleaner')

**Iteration Cycle**
1. **Snapshot**: Capture current state — test durations, failure rates, coverage %, open bug count.
2. **One Change**: Make a single significant, reviewable change. Examples:
   - Replace brittle XPath selectors with data-testid attributes
   - Split a monolithic test file into domain-specific modules
   - Add retry logic with explicit failure logging
   - Introduce parallel execution with isolated test accounts
3. **Live Verify**: Run the affected tests locally and in CI. Compare before/after metrics.
4. **Independent Review**: Have another agent or human review the diff for unintended side effects.
5. **Commit Checkpoint**: Only commit when verification passes. Tag the commit with metrics.
6. **Update Progress File**: Log decisions, blockers, metric changes, and next action.

**Stop Conditions**
- All satisfaction criteria are met
- Two consecutive iterations show no metric improvement
- A blocker requires operator escalation (budget, tool limitation, architectural disagreement)

**Failure Handling**
- If a change breaks existing tests: revert immediately, log the failure mode, try a smaller increment.
- If verification is inconclusive: extend the test sample, add instrumentation, or break the change into smaller pieces.
- If the goal shifts mid-loop: pause, update the satisfaction criteria with operator approval, and restart the iteration counter.
