name: "k6 負載測試與效能分析"

nodes:
  - id: configure_k6
    type: cli
    purpose: Prepare k6 test scripts and thresholds configuration
    runtime:
      command: >
        k6 inspect --execution-requirements scripts/load-test.js
    outputs: [test_config, baseline_thresholds]
    timeout_sec: 30

  - id: run_load_test
    type: cli
    purpose: Execute k6 load test against target environment
    runtime:
      command: >
        k6 run scripts/load-test.js
        --out json=results.json
        --out csv=results.csv
        --vus 100 --duration 5m
      env:
        K6_TARGET_URL: "https://staging.example.com"
    inputs: [test_config]
    outputs: [raw_results, summary_metrics]
    timeout_sec: 600
    explain: |
      Runs with 100 virtual users for 5 minutes.
      Outputs both JSON (for analysis) and CSV (for reporting).

  - id: analyze_metrics
    type: agent
    purpose: Analyze load test results and compare against baselines
    runtime:
      provider: openai
      model: gpt-4
    inputs: [raw_results, baseline_thresholds]
    outputs: [analysis_report, regression_detected]
    explain: |
      The AI agent compares p95 latency, error rates, and throughput
      against historical baselines. It identifies regressions and
      provides recommendations for performance improvements.

  - id: generate_report
    type: cli
    purpose: Generate visual performance report with charts
    runtime:
      command: >
        k6 report results.json --output report.html
