Integrating K6 Synthetic Tests for OpenClaw Rating API Edge with GitHub Actions

Answer: To integrate K6 synthetic tests for the OpenClaw Rating API Edge into a GitHub Actions CI/CD workflow, you create a K6 test script, store it in your repository, define a GitHub Actions workflow that runs the script on each push or pull request, configure the OpenClaw API credentials as secrets, and then use the workflow’s results to gate deployments.

Introduction

Developers and DevOps engineers constantly battle the “it works on my machine” syndrome. When you expose an API like the OpenClaw Rating API Edge to external consumers, you need confidence that every code change preserves performance and reliability. K6 synthetic testing provides lightweight, script‑driven load tests that can be executed in CI/CD pipelines. By coupling K6 with GitHub Actions, you achieve API performance testing that runs automatically on every commit, pull request, or release.

This guide walks you through a step‑by‑step integration, from installing K6 to verifying results, and shows how the OpenClaw Rating API Edge can be hosted on UBOS for seamless production deployment.

Prerequisites

• A GitHub repository containing the OpenClaw service code.
• Access to the UBOS platform overview (or any compatible Linux host) where the API will run.
• Node.js (>=14) and npm installed locally for script scaffolding.
• K6 installed on your development machine – see the official K6 installation guide.
• GitHub repository secrets:
  • OPENCLAW_API_KEY – your OpenClaw API token.
  • K6_CLOUD_TOKEN (optional) – if you push results to k6 Cloud.
• Basic familiarity with YAML and shell scripting.

Setting up K6 Synthetic Tests

K6 tests are written in JavaScript, making them easy to version alongside your application code. Below is a minimal synthetic test that validates the /rate endpoint of the OpenClaw Rating API Edge.

// file: tests/openclaw-rate-test.js
import http from 'k6/http';
import { check, sleep } from 'k6';

export const options = {
  stages: [
    { duration: '30s', target: 10 }, // ramp‑up to 10 virtual users
    { duration: '1m', target: 10 },  // stay at 10 VUs
    { duration: '30s', target: 0 },  // ramp‑down
  ],
  thresholds: {
    http_req_duration: ['p(95)<500'], // 95% of requests  r.status === 200,
    'response time  r.timings.duration < 500,
  });

  sleep(1);
}

Key points in the script:

• Environment variables (OPENCLAW_BASE_URL and OPENCLAW_API_KEY) keep secrets out of source control.
• The options.stages block defines a simple load profile.
• Thresholds enforce performance SLAs directly in the test.

Commit the tests/ folder to your repository. You can now run the test locally with:

export OPENCLAW_BASE_URL=https://api.openclaw.example.com
export OPENCLAW_API_KEY=your_api_key
k6 run tests/openclaw-rate-test.js

Creating the GitHub Actions Workflow

GitHub Actions uses YAML files stored in .github/workflows/. The following workflow runs the K6 test on every push to main and on pull‑request events.

# file: .github/workflows/k6-openclaw.yml
name: K6 Synthetic Test – OpenClaw Rating API Edge

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:
  k6-test:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v3

      - name: Set up Node.js (for any npm scripts)
        uses: actions/setup-node@v3
        with:
          node-version: '18'

      - name: Install K6
        run: |
          sudo apt-get update
          sudo apt-get install -y gnupg2 curl
          curl -s https://dl.k6.io/key.gpg | sudo apt-key add -
          echo "deb https://dl.k6.io/deb stable main" | sudo tee /etc/apt/sources.list.d/k6.list
          sudo apt-get update
          sudo apt-get install -y k6

      - name: Export environment variables
        env:
          OPENCLAW_BASE_URL: ${{ secrets.OPENCLAW_BASE_URL }}
          OPENCLAW_API_KEY: ${{ secrets.OPENCLAW_API_KEY }}
        run: |
          echo "OPENCLAW_BASE_URL=${{ secrets.OPENCLAW_BASE_URL }}" >> $GITHUB_ENV
          echo "OPENCLAW_API_KEY=${{ secrets.OPENCLAW_API_KEY }}" >> $GITHUB_ENV

      - name: Run K6 synthetic test
        run: k6 run tests/openclaw-rate-test.js

      # Optional: push results to k6 Cloud for richer dashboards
      - name: Upload results to k6 Cloud
        if: env.K6_CLOUD_TOKEN != ''
        env:
          K6_CLOUD_TOKEN: ${{ secrets.K6_CLOUD_TOKEN }}
        run: |
          k6 cloud tests/openclaw-rate-test.js

Explanation of the workflow steps:

• Checkout repository – pulls your code into the runner.
• Set up Node.js – ensures any npm‑based tooling works.
• Install K6 – uses the official Debian repo for the latest stable version.
• Export environment variables – reads secrets from GitHub and makes them available to the test script.
• Run K6 synthetic test – executes the script and fails the job if thresholds are not met.
• Upload results to k6 Cloud – optional step for visual analytics.

Configuring OpenClaw Rating API Edge

Before the CI pipeline can hit the API, you must provision the OpenClaw Rating API Edge on a reliable host. UBOS offers a one‑click deployment model that abstracts away server management.

1. Log in to the UBOS partner program and navigate to the Enterprise AI platform by UBOS.
2. Select “Create New Service” and choose the OpenClaw Rating API Edge template from the UBOS templates for quick start.
3. Configure environment variables:
   • OPENCLAW_DB_URL – connection string to your PostgreSQL instance.
   • OPENCLAW_SECRET – a strong random secret for JWT signing.
4. Set the desired scaling policy in the Workflow automation studio to auto‑scale based on CPU or request latency.
5. Deploy the service. UBOS will provision a Docker container, expose it behind a managed edge, and provide you with a stable BASE_URL that you can store as a GitHub secret (OPENCLAW_BASE_URL).

Once deployed, you can test the endpoint manually with curl or Postman to confirm it returns a 200 OK for a valid rating payload.

Deployment Steps

With the API running and the CI pipeline ready, the final piece is to automate the production rollout only when performance tests pass.

# Extend the previous workflow with a deployment job
name: CI/CD – OpenClaw Rating API Edge

on:
  push:
    branches: [ main ]

jobs:
  test:
    # (previous test job definition)
    ...

  deploy:
    needs: test
    runs-on: ubuntu-latest
    if: success()   # only run if test job succeeded
    steps:
      - name: Checkout repository
        uses: actions/checkout@v3

      - name: Trigger UBOS deployment
        env:
          UBOS_API_TOKEN: ${{ secrets.UBOS_API_TOKEN }}
          SERVICE_ID: ${{ secrets.OPENCLAW_SERVICE_ID }}
        run: |
          curl -X POST "https://api.ubos.tech/v1/services/${SERVICE_ID}/deploy" \
            -H "Authorization: Bearer $UBOS_API_TOKEN" \
            -H "Content-Type: application/json"

This deployment job uses a simple curl call to the UBOS API (documented on the About UBOS page) to trigger a new release. Because the job is gated by if: success(), any regression in the K6 synthetic test will block the rollout, preserving API reliability.

Verifying the Integration

After the workflow runs, you should verify three things:

1. CI Pass/Fail Status – Open the Actions tab in GitHub; a green checkmark indicates that K6 thresholds were met.
2. Performance Dashboard – If you enabled k6 Cloud, navigate to the k6 Cloud dashboard to view response‑time trends, error rates, and VU distribution.
3. Live API Health – Use the UBOS portfolio examples to see a real‑time health widget that pings the Rating API every 30 seconds.

For a quick sanity check, you can also run the test manually in the CI environment using the workflow_dispatch trigger:

on:
  workflow_dispatch:
    inputs:
      run_type:
        description: 'Run type (full or smoke)'
        required: true
        default: 'smoke'
