k6 Performance Testing Skill

Overview

This skill provides expert-level capabilities for k6-based performance testing, enabling load test scripting, execution, metrics analysis, and integration with monitoring systems.

Capabilities

Script Development

• Write k6 load test scripts in JavaScript
• Implement virtual user scenarios
• Configure data parameterization
• Handle authentication in load tests

Load Profile Configuration

• Configure ramp-up patterns
• Define steady-state load levels
• Implement spike testing scenarios
• Configure soak testing profiles

Metrics & Analysis

• Analyze k6 metrics (response time, throughput, errors)
• Configure thresholds and checks
• Generate PromQL queries from k6 output
• Interpret percentile distributions

Cloud Integration

• Configure k6 Cloud execution
• Distributed load generation
• Cloud results analysis

Dashboard Integration

• Integration with Grafana dashboards
• InfluxDB metrics export
• Real-time monitoring setup

Target Processes

• performance-testing.js - Performance test implementation
• api-testing.js - API performance validation
• continuous-testing.js - CI/CD performance gates

Dependencies

• k6 - Load testing tool
• Grafana (optional) - Dashboards
• InfluxDB (optional) - Metrics storage

Usage Example

{
  kind: 'skill',
  skill: {
    name: 'k6-performance',
    context: {
      action: 'execute-load-test',
      script: 'tests/performance/load.js',
      vus: 100,
      duration: '5m',
      thresholds: {
        'http_req_duration': ['p(95)<500']
      }
    }
  }
}

Configuration

The skill can execute k6 scripts locally or configure cloud execution for distributed load testing.
