Breaking changes for experimental modules

Remove experimental k6/experimental/webcrypto module #​4851

The WebCrypto API has been available globally since v1.0.0-rc1 (or v0.58.0), and now the experimental import (k6/experimental/webcrypto) is no longer available.

The required change for users is to remove the import; the rest of the code should work.

New features

New count method for the browser module's Locator API #​4797

The new locator.Count method returns the number of elements matching the locator. Unlike other Locator API methods, locator.Count returns the result immediately and doesn't wait for the elements to be visible.

import { expect } from "https://jslib.k6.io/k6-testing/0.4.0/index.js";
import { browser } from 'k6/browser'

export const options = {
  scenarios: {
    ui: {
      executor: 'shared-iterations',
      options: {
        browser: {
          type: 'chromium',
        },
      },
    },
  },
}

export default async function () {
  const page = await browser.newPage()
  await page.goto('https://quickpizza.grafana.com/login')

  expect(await page.locator('input').count()).toEqual(3);

  await page.close();
}

New nth, first and last methods for the browser module's Locator API #​4825

The new Locator API methods, nth, first, and last, can select a single element from multiple elements matched by a locator. For example, selecting a single item from a catalogue of items on an e-commerce website. Because items in this catalogue generally change often and selecting an exact element may fail in future test runs, the new methods help to prevent flaky tests, leading to more reliable tests.

import { expect } from "https://jslib.k6.io/k6-testing/0.4.0/index.js";
import { browser } from 'k6/browser'

export const options = {
  scenarios: {
    ui: {
      executor: 'shared-iterations',
      options: {
        browser: {
          type: 'chromium',
        },
      },
    },
  },
}

export default async function () {
  const page = await browser.newPage()
  await page.goto('https://quickpizza.grafana.com')

  await expect(await page.locator('p').first()).toContainText('QuickPizza');
  await expect(await page.locator('p').nth(4)).toContainText('QuickPizza Labs.');
  await expect(await page.locator('p').last()).toContainText('Contribute to QuickPizza');

  await page.close();
}

Roadmap

Official Testing/Assertions Module

We're working to integrate a built-in testing and assertions module that's compatible with Playwright's in k6. You can try the current implementation using the k6 testing jslib, which serves as our work-in-progress implementation for what will become the official k6/test module (final name TBD). We'd love your feedback on issue #​4805.

Enhanced Machine-Readable Test Results

We're developing the next version of k6's end-of-test summary to make it easier to integrate test results into CI/CD pipelines and automated workflows. This new format will be officially supported, versioned, and designed specifically for programmatic use. Follow our progress, and provide us with feedback on issue #​4803.

v1.0.0

Compare Source

Grafana k6 v1.0 is here! 🎉

After 9 years of iteration and countless community contributions, we're thrilled to announce Grafana k6 v1.0.

While many features and capabilities in this release were introduced gradually in previous versions, k6 v1.0 marks a turning point: a commitment to stability, formal support guarantees, and transparency in how we evolve and develop the project from here. This milestone is more than a version number; it's about trust, reliability, and empowering you to test confidently.

Thank you, k6 community! 🌍

This release wouldn't be possible without you:

• ⭐️ 27000+ GitHub stars.
• 🧠 9000+ git commits.
• 🤝 200+ contributors.
• 🔁 Countless test runs of any scale, in every timezone.

It's been amazing to watch k6 grow from a simple load testing command-line tool into a comprehensive reliability tool, used by teams worldwide and supported by a passionate and dedicated community.

To everyone who filed bugs, built extensions and libraries, or championed k6:️
Thank you! You've shaped what k6 is today. 🙇‍♂️

What's New in k6 1.0?

1. Stability You Can Build On

• ✅ Semantic Versioning: k6 now follows Semantic Versioning 2.0. Breaking changes will only happen in major releases, with prior deprecation warnings.
• 🔒 2-Year Support Guarantees: Every major version will be supported with critical fixes for at least two years; upgrade on your schedule.
• 📦 Public API Surface: We've established a clearly delineated and supported API surface for the k6 codebase. Extensions, integrations, and projects building on top of the k6 code now have a stable foundation to rely on.

🔎 Read more in our versioning and stability guarantees guide.

2. First-Class TypeScript Support

Write type-safe and maintainable tests—no transpilation needed. Simply save your file with a .ts extension and run it directly using k6 run script.ts.

import http from 'k6/http';  

// PizzaRequest defines the request body format the quickpizza API expects
export interface PizzaRequest {
    maxCaloriesPerSlice: number;
    mustBeVegetarian: boolean;
}

export default function () {  
    const payload: PizzaRequest = {
        maxCaloriesPerSlice: 500, // Type-checked!  
        mustBeVegetarian: true,
    }

  http.post(
    'https://quickpizza.grafana.com/api/pizza',
    JSON.stringify(payload),
    { 
        headers: { 
          "Content-Type": "application/json",
          "Authorization": "Token " + "abcdef0123456789"
        } as Record<string, string>
    });  
}  

3. Extensions Made Simple

With k6 v1.0, extensions now work out of the box in k6 cloud run and k6 cloud run --local-execution. Support for k6 run is coming soon.

✅ No more xk6 toolchain.
✅ No manual builds.
✅ Import an extension's module and go.

import faker from 'k6/x/faker';

export default function () {
  console.log(faker.person.firstName());
}

To try the experimental feature, first enable its feature flag, then run it on Grafana Cloud with the following command:

K6_BINARY_PROVISIONING=true k6 cloud run script.js,

or if you want to run it locally and stream the results to Grafana Cloud then use:

K6_BINARY_PROVISIONING=true k6 cloud run --local-execution script.js

4. Revamped test summary

The new end-of-test summary makes it easier to understand results and spot issues:

• 📊 Hierarchical output: Metrics are grouped by scenario, group, and category.
• ✅ Improved thresholds & checks: Clearer layout for faster debugging.
• 🔍 Multiple summary modes:
  • compact (default): big picture results, focusing on essentials.
  • full: full picture results, providing granularity.

k6 run --summary-mode=full script.ts

5. Quality of Life Upgrades

• Stable modules: k6/browser, k6/net/grpc, and k6/crypto are now production-ready.
• Improved Grafana Cloud integration: Stream local test results to Grafana Cloud with k6 cloud run --local-execution.

v0.59.0

Compare Source

The v0.59.0 release mirrors the previous v1.0.0-rc2 release to allow automation tools to recognize it as the latest version.
For example, Homebrew's k6 formulae and pkg.go.dev do not automatically fetch unstable versions such as v1.0.0-rc2, which is legitimately the expected behavior for these tools.

However, this has been the default for all previous v0.* releases, where they were considered the latest stable version—even if they were under a version typically associated with unstable releases. To address this, we will continue releasing mirrored versions under v0.* for necessary release candidates.

This practice will end once the official stable v1.0.0 release is available, after which we will follow the standard SemVer lifecycle to simplify the workflow for everyone.

The release notes for v1.0.0-rc2 provide a detailed look at all the changes that have been implemented since v1.0.0-rc1/v0.58.0 and are now part of this version.

v0.57.0

Compare Source

k6 v0.57.0 is here 🎉! This release includes:

• Introducing helpers for functional testing.
• The k6 new command now supports templates and ProjectIDs.
• The k6/experimental/csv module gets a new asObjects option.
• We no longer support the k6/experimental/browser module, in favor of k6/browser.
• Moving most of non-public APIs to the internal package.

Breaking changes

• #​4161 Drops k6/experimental/browser. If you're still using it, follow the instructions to move to the graduated and stable k6/browser module.
• #​4133 Moves all not publicly used APIs in internal package. This was based on the publicly available extensions for k6 and may break private ones. More APIs will likely be removed or updated in follow-up releases after this more mechanical change.
• #​4292 TypeScript is automatically supported and recognized if the script files use the .ts extension. It also deprecates experimental_enhanced compatibility mode as it is no longer necessary.

New features

New functional testing focused official jslib k6-testing

The k6 team has been developing a new official jslib dedicated to functional testing. While it is still under active development and will potentially see breaking changes, the set of APIs and behaviors it offers are meant to make their way into k6 eventually, and it is now available for early feedback.

k6-testing is a k6 JavaScript library that offers a seamless way to write functional tests in k6, using a Playwright-compatible assertions API. It exposes an expect function, with which assertions can be performed using specific matchers that reflect the expected results.
Unlike current k6's check when expects assertions fail, the test will immediately fail with a clear error message, including the expected and actual values in a similar fashion to what users would observe when using Playwright assertions.

There are many generic matchers (and more to come), such as toEqual, toBe, or toBeTruthy, to only name a few, that can be used to assert conditions during a k6 test.

import { expect } from 'https://jslib.k6.io/k6-testing/0.2.0/index.js';

export default function () {
    const response = http.get('https://test.k6.io');
    expect(response.status).toEqual(200);
    expect(response.body).toBeTruthy();
    expect(response.json()).toEqual(JSON.stringify({ message: 'Hello, world!' }));
}

k6-jslib-testing also includes browser-specific async matchers that wait until the expected condition is met such as toBeVisible, toBeDisabled, or toBeChecked, to name a few.

import { expect } from "https://jslib.k6.io/k6-testing/0.2.0/index.js";
import { browser } from "k6/browser";

export const options = {
  scenarios: {
    ui: {
      executor: "shared-iterations",
      options: {
        browser: {
          type: "chromium",
        },
      },
    },
  },
};

export default async function () {
  const page = await browser.newPage();

  try {
    // Navigate to the page
    await page.goto("https://test.k6.io/my_messages.php");

    // Type into the login input field: 'testlogin'
    const loc = await page.locator('input[name="login"]');
    await loc.type("testlogin");

    // Assert that the login input field is visible
    await expect(page.locator('input[name="login"]')).toBeVisible();

    // Expecting this to fail as we have typed 'testlogin' into the input instead of 'foo'
    await expect(page.locator('input[name="login"]')).toHaveValue("foo");
  } finally {
    await page.close();
  }
}

It is currently available as part of the jslib.k6.io repository and is available to use in your k6 tests by adding the following import:

import { expect } from "https://jslib.k6.io/k6-testing/0.2.0/index.js";

Try it out and give us feedback or contribute to the project on the k6-jslib-testing repository!

--template and --project-id flags for k6 new command #​4153

The k6 new command has been revamped to provide an improved experience when scaffolding new k6 tests. It now supports a --template flag with options such as minimal, protocol, and browser, letting you generate a script tailored to your specific use case.

The command also now accepts a --project-id flag, which allows you to easily parameterize the test's Grafana Cloud configuration.

### Create a new k6 script using the 'protocol' template
$ k6 new --template protocol

### Create a Grafana k6 cloud-ready script with a specific project ID
$ k6 new --project-id 12345

New asObjects option in k6/experimental/csv module #​4295

The CSV module's parsing operations now support the asObjects option, which enables parsing CSV data into JavaScript objects instead of arrays of strings (the default behavior).

When asObjects is set to true, the module parses CSV data into objects where:

• Column names from the header row become object keys.
• Column values become the corresponding object values.
• An error is thrown if no header row exists or if options modify the parsing start point.

With the option set to true,

import http from 'k6/http';
import csv from 'k6/experimental/csv';

const csvData = csv.parse('data.csv', { asObjects: true });

the following CSV file:

name,age,city
John,30,New York
Jane,25,Los Angeles

will be parsed into the following JavaScript objects:

[
  { name: 'John', age: '30', city: 'New York' },
  { name: 'Jane', age: '25', city: 'Los Angeles' },
]

Refer to the CSV module's documentation for more information.
