on GitHub

xk6-browser v0.8.0 is here! 🎉

This release contains preparation for the upcoming xk6-browser and k6 merge, preparations for the upcoming Async API features, bug fixes, and code refactoring.

Experimental Module Merge into k6

We've been busy preparing for this big change that will occur very soon 🤞. We have refactored the code in preparation for the merge into k6 (see the related issue list). This will mean that all future releases of xk6-browser will also be part of the k6 releases (as an experimental module). Merging xk6-browser into k6 will allow you to run both the protocol and browser tests using the same k6 command line tool. This will also increase the reach and visibility of xk6-browser and allow us to collect more feedback and guidance from the community to tailor our product to your needs. It's worth noting that we're not merging the two code bases into a single one. xk6-browser will still be in its own repository.

As an experimental module, some of our APIs are likely to change, causing breaking changes in future releases—for example, now that we have async/await keyword support, we're going to move most of our APIs to async. Changes in APIs also means that your Playwright scripts will also start to work in xk6-browser with less and less tweaking of your xk6-browser test scripts in the upcoming releases—As per our rough compatibility goal with Playwright APIs.

Currently, browser based tests can only be performed within your own test environments, and it won't be available in the cloud (yet). Keep your eyes peeled though on future releases, and the blog to hear more on the public launch of browser testing in the cloud.

With this release we are continuing to build and upload the artifacts (binaries) for you to download and work with. In the near future we intend to stop that, and instead we will redirect you to the k6 repo, where you will be able to download the latest binary with browser test functionality. We may also stop releasing the release notes here and move them to the k6 release notes. We will create a blog post outlining these details soon.

Improvements

• Convert promisified (.then()) examples to async/await. #703

  Now all our examples use async/await instead of the promise .then() chains. Please look at the examples/ folder to see how we use the new feature. We're changing the meaning of this folder and will use it for internal JavaScript tests instead of showing how to use the xk6-browser extension.

• Log a friendly message if the browser process closes before xk6-browser is able to connect to the browser. #735

Documentation

• We're updating all our docs so that they reflect the merge and the async/await changes. These updates will be released after the merge and the latest version of k6 has been released.

Internal bug fixes and improvements

• Pre-merge: Map k6-browser Async API to Goja. #683

  This is the groundwork for abstracting our internals to get ready for the merge and make it straightforward to upgrade our API to async in the upcoming releases. With this work, we're now able to unlock the following features:

  • Provide an easy switch to the k6 browser Async API.
  • Unlock merging of k6 browser to k6 core: Mapping Async APIs.
  • Increase developer productivity by clearly separating the k6 browser code and Goja.

• Fix the race condition in frame management. #696

• Fix dismiss dialog test bug. #713

• Fix frame manager navigate frame bug. #714

• Fix lifecycle tests bug. #712

• Several other refactors and bug fixes to improve maintainability and stability: (#694, #699, #700, #723, #716, #734, #740, #741).
