Step 3: Gather Evidence

STEP GOAL

Collect measurable evidence to evaluate each NFR category.

MANDATORY EXECUTION RULES

• 📖 Read the entire step file before acting
• ✅ Speak in {communication_language}

---

EXECUTION PROTOCOLS:

• 🎯 Follow the MANDATORY SEQUENCE exactly
• 💾 Record outputs before proceeding
• 📖 Load the next step only when instructed

CONTEXT BOUNDARIES:

• Available context: config, loaded artifacts, and knowledge fragments
• Focus: this step's goal only
• Limits: do not execute future steps
• Dependencies: prior steps' outputs (if any)

MANDATORY SEQUENCE

CRITICAL: Follow this sequence exactly. Do not skip, reorder, or improvise.

1. Evidence Sources

Collect evidence for:

• Performance: load tests, metrics, response time data
• Security: scans, auth tests, vuln reports
• Reliability: error rates, burn-in runs, failover tests
• Maintainability: test quality, code health signals
• Other categories: logs, monitoring, DR drills, deployability checks

---

2. Browser-Based Evidence Collection (if tea_browser_automation is cli or auto)

Fallback: If CLI is not installed, fall back to MCP (if available) or skip browser-based evidence collection.

For performance and security categories, CLI can gather live evidence:

Performance evidence (page load, response times):

1. playwright-cli -s=tea-nfr open <target_url>
2. playwright-cli -s=tea-nfr network → capture response times and payload sizes
3. playwright-cli -s=tea-nfr screenshot --filename={test_artifacts}/nfr/perf-<page>.png
4. playwright-cli -s=tea-nfr close

Session Hygiene: Always close sessions using playwright-cli -s=tea-nfr close. Do NOT use close-all — it kills every session on the machine and breaks parallel execution.

Store artifacts under {test_artifacts}/nfr/

---

3. Evidence Gaps

If evidence is missing for a category, mark that category as CONCERNS.

---

4. Save Progress

Save this step's accumulated work to {outputFile}.

• If {outputFile} does not exist (first save), create it using the workflow template (if available) with YAML frontmatter:

  ---
  stepsCompleted: ['step-03-gather-evidence']
  lastStep: 'step-03-gather-evidence'
  lastSaved: '{date}'
  ---
  

  Then write this step's output below the frontmatter.

• If {outputFile} already exists, update:

  • Add 'step-03-gather-evidence' to stepsCompleted array (only if not already present)
  • Set lastStep: 'step-03-gather-evidence'
  • Set lastSaved: '{date}'
  • Append this step's output to the appropriate section of the document.

Load next step: {nextStepFile}

🚨 SYSTEM SUCCESS/FAILURE METRICS:

✅ SUCCESS:

• Step completed in full with required outputs

❌ SYSTEM FAILURE:

• Skipped sequence steps or missing outputs Master Rule: Skipping steps is FORBIDDEN.
