14-Module Course Outline

Performance testing fundamentals — why, when, and what to measure
Test environment setup — Docker, perf-containers, base images
HTTP/S testing — sampler design, parameterisation, assertions
Authentication — Basic, Bearer, OAuth 2.0 flows
Data-driven testing — CSV feeds, random data, dummydatagenpro integration
Correlation and extractors — regex, JSON path, XPath, boundary
Load profiles — ramp, step, spike, soak
Think times and pacing — realistic user simulation
Assertions and SLA gates — response code, time, content, Apdex
Protocol-specific testing — one module per tool covering gRPC, WebSocket, Kafka
CI/CD integration — GitHub Actions, GitLab CI, Jenkins, Azure DevOps
Results analysis — perf-reporting, perf-results-db, trend baselines
Debugging — reading logs, diagnosing bottlenecks, flame graphs
Advanced patterns — parameterised load, distributed execution, HAR correlation

Desktop App

The Tauri/Svelte desktop app lets you:

Browse all templates with protocol and tool filters
Open templates directly in JMeter / k6 CLI / IntelliJ
Manage your license key
Check for template updates

Available for Windows, macOS, and Linux (AppImage).

Using Templates

Templates are pre-configured, commented, and ready to run. Each template includes:

A working test plan/script for the target protocol
A perf-ecosystem.yml example for the scenario
A README with setup instructions for the target server/service

JMeter template structure

jmeter/
  http-rest/
    test-plan.jmx
    data/
      users.csv
    README.md
  grpc/
    test-plan.jmx
    proto/
      service.proto
    README.md

k6 template structure

k6/

perf-containers Integration

Templates are designed to run with the perf-containers Docker images, which include all required plugins and protocol drivers:

# Run a JMeter template via Docker
docker run --rm \
  -v $(pwd)/jmeter/http-rest:/test \
  ghcr.io/markslilley/perf-jmeter:latest \
  jmeter -n -t /test/test-plan.jmx -l /test/results.jtl
