Breaking changes

Transition browser APIs to Async

In the last release notes we mentioned this breaking change, and we wanted to remind and update you on the plan. In the next release (v0.52.0), most of the synchronous browser APIs will be migrated to be asynchronous (promisifying them). We expect this will affect most if not all of our users.

This breaking change will require you to add await in front of most of the browser module APIs. Without this await you will witness undocumented and unknown behavior during the runtime. To make the migration simpler we advise that you work with the latest k6 type definitions.

You can find a list of all the APIs that we expect to convert to async in a comment in issue browser#428.

Awaiting on something that’s not a thenable just returns that value, which means you can add the await keyword today on the APIs that will become async to future proof your test scripts.

Here are the reasons for making this large breaking change:

1. Most browser APIs use some form of long-running IO operation (networking) to perform the requested action on the web browser against the website under test. We need to avoid blocking JavaScript's runtime event loop for such operations.
2. We're going to add more asynchronous event-based APIs (such as page.on) that our current synchronous APIs would block.
3. To align with how developers expect to work with JavaScript APIs.
4. To have better compatibility with Playwright.

As a starting point, we have migrated a single API (the tap method), which you can find the details below that will help visualize the upcoming breaking changes.

Browser Tap is now an async method grafana/xk6-browser6

This release converts the Tap method in the browser module into an asynchronous method. This change is necessary to ensure that the method can be used in async contexts and to align with the rest of the browser module's planned asynchronous API. To use the Tap method, you must now add the await keyword before the method call.

Affected components:

• locator.tap
• page.tap
• frame.tap
• elementHandle.tap

See the following example for how to use the Tap method after this change:

Before:

import browser from 'k6/experimental/browser'
// ...
export default function () {
// ...
page.tap(selector, { modifiers: ["Alt", "Control", "Meta", "Shift"] });
</tr></table>
