Testing/k6 load testing

[Jingyan5]

k6 - Load Testing Tool Integration

Installation Evidence

• k6 v1.6.1 installed via apt on the VM
• k6-tests/load-test.js test script created

Artifacts

• k6-tests/k6-output.txt — terminal output from k6 load test run

Results Summary

• 300 total requests, 10 virtual users over 30 seconds
• 100% success rate (all checks passed)
• Avg response time: 18.72ms, max: 178.79ms
• All responses under 500ms threshold

Pros

• Zero code changes required to existing codebase
• Immediately produces rich, quantitative performance metrics
• Simulates real concurrent user traffic
• Simple JavaScript-based test scripts
• Great for catching performance regressions over time
• Can integrate into GitHub Actions CI pipeline

Cons

• Requires the app to be running during the test
• Only tests performance, not code quality or security
• Results vary depending on VM load at time of test
• No built-in comparison between runs

Customization Notes

• vus and duration can be tuned to simulate heavier traffic
• Can add multiple endpoints to test different routes
• Thresholds can be set to auto-fail if response times exceed limits
