K6-junit NPM | npm.io

k6-junit

k6 JUnit summary exporter library.

Usage

import {jUnit} from "k6-junit";
// ...
export function handleSummary(data) {
    console.log('Preparing the end-of-test summary...');
    return {
        "./test-results.xml": jUnit(data)
    };
}

Typescript integration

Based on k6-template-typescript.

Add dev-dependency to package.json:

{
  "devDependencies": {
    "k6-junit": "X.X.X"
  }
}

Resolve k6-junit package as internal dependecy in webpack.config.js:

// ...
module.exports = {
  // ...
    externals: [
        function ({context, request}, c) {
            if (request.startsWith('k6') || request.startsWith('https://')) {
                return request === 'k6-junit' ? c() : c(null, 'commonjs ' + request);
            }
            return c();
        },
    ],
  // ...
}

Using without transpiling

In case when it is necessary to avoid transpiling to js and run k6 right on typescript tests, you should modify import statement:

import {jUnit} from "./node_modules/k6-junit/index.js";

Configuration

Since your project may have its own features there is a possibility to adjust behaviour to your needs. There are several configuration parameters available. Please, see their reference below:

Parameter Name	Description	Default value
includeThresholds	Allows you to control the inclusion of Threshold metrics during the export	true
testCasePassCondition	Allows you to control the logic which decides whether testCase passed or not	passed > 0 && failed === 0
maxGroupNestingLevel	Defines the maximum level of group nesting, more nested groups will be flattened as test-cases	1

If you need to override default values, please call jUnit function with cfg argument defined. So that, your specific configuration will be used by the library.

import {jUnit} from "k6-junit";
// ...
    return {
        "./test-results.xml": jUnit(data, {
           includeThresholds: false,
           testCasePassCondition: (passed, failed) => passed > 0 && failed <= passed,
           maxGroupNestingLevel: 2
        })
    };
// ...
