We're excited to announce the next major release of the StrykerJS: StrykerJS 6.0.

StrykerJS now supports native ECMAScript modules, or ESM for short. To make this work, we changed some parts of StrykerJS, which includes small (yet technically breaking) changes. As a bonus, we've improved performance considerably in some use cases! We're curious to know what you think. Why not try it today?

We're proud to announce the next major release of the Stryker mutation testing framework for JavaScript and friends: Stryker 4.0.

This release marks a fundamental shift in the way Stryker works internally. It now uses "mutation switching", which improves performance and usability, similar to how Stryker.NET and Stryker4s already work. This change, unfortunately, couldn't be done without breaking changes. See the breaking changes paragraph if you're interested.

If you've used Stryker before, you'll know that it produces a gorgeous report you can view in the browser. It works by generating HTML files based on the events raised by Stryker. During development of Stryker4s and Stryker.NET, we realized that producing the same report would be a lot of work.

Instead of a new HTML reporter implementation for each Stryker framework, we've decided to move the logic of presenting the report to your browser. That way, any framework can support an HTML report simply by producing a JSON file.

We call it mutation testing elements and it is implemented using the mature web components suite of features. You can now use it in Stryker, Stryker.NET and Stryker4s
