📋 Prerequisites

Before using this package, ensure you have the following installed:

1️⃣ Node.js (>=18.x) - Download
2️⃣ NPM (Comes with Node.js)
3️⃣ K6 for load testing - Install K6
4️⃣ Slack & Teams Webhook URLs (Saved in .env)

📦 Installation

npm install --save-dev k6-slack-ms-teams-reporter

🔧 Configuration

1️⃣ Set Up Environment Variables

Create a .env file and add your Slack or Teams webhook URL:

SLACK_WEBHOOK_URL=https://hooks.slack.com/services/your-webhook-url
TEAMS_WEBHOOK_URL=https://outlook.office.com/webhook/your-webhook-url

📊 Generating Reports

To generate HTML and JSON reports, modify your K6 script:

import { htmlReport } from "https://raw.githubusercontent.com/benc-uk/k6-reporter/main/dist/bundle.js";

export function handleSummary(data) {
  return {
    "reports/k6TestReport.html": htmlReport(data),
    "reports/k6TestResults.json": JSON.stringify(data),
    stdout: textSummary(data, { indent: " ", enableColors: true }),
  };
}

This will create:
📜 HTML Report: reports/k6TestReport.html
📜 JSON Report: reports/k6TestResults.json

🚀 Sending Reports

1️⃣ CLI Usage

Send Report to Slack

npx k6-slack-ms-teams-reporter --target slack --report-name k6TestResults

Send Report to Microsoft Teams

npx k6-slack-ms-teams-reporter --target teams --report-name k6TestResults

🛠️ Custom Reporter Options

You can configure custom options via reportConfig.json:

Create a reportConfig.json file in your project:

{
  "target": "slack",
  "reportName": "k6TestResults",
  "verbose": true,
  "jsonReportPath": "artifacts/loadTestResults.json",
  "htmlReportUrl": "artifacts/loadTestReport.html",
  "ciPipelineUrl": "https://gitlab.com/myproject/-/jobs/"
}

Users can also create a reportConfig.js file like this:

export default {
  reporter: "k6-slack-ms-teams-reporter",
  target: "slack",
  reportName: "k6TestResults",
  verbose: false,
  jsonReportPath: "examples/reports/k6TestResults.json",
  htmlReportUrl: "http://127.0.0.1/examples/reports/k6TestResults.html",
  ciPipelineUrl: "https://gitlab.com/myproject/-/jobs/",
};

Then run the reporter:

npx k6-slack-ms-teams-reporter

The reporter will automatically pick up configurations from reportConfig.json or reportConfig.js.
