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.
