Support for Vitest v3.0.x+ (Jan 23 2025)

Wallaby now supports the latest version of vitest (v3.0.x+). The recent update of vitest included breaking changes that required updates to Wallaby's vitest integration.

Value Peek (Jan 21 2025)

Wallaby for VS Code and JetBrains editors now supports Value Peek, a way to quickly see any value just by hovering over it. Wallaby will handle execution of the relevant tests to provide values, which will be displayed in the hover. To keep your editor clutter-free, values shown this way will not appear next to your code by default (but can be made to appear using the "Explore Value" action available in the hover). Value Peek can be toggled on or off to fit with your workflow.

Introducing Wallaby v2 (Oct 17 2024)

We’ve re-imagined Wallaby.js to deliver more power, flexibility, and a seamless experience across all editors. Wallaby v2 introduces an all-new UI, enhanced debugging tools like the Interactive Time Travel Debugger, and advanced test execution monitoring. With Linked and Standalone modes, it supports any editor, making it easier than ever to streamline your workflow. Read more in our blog.

Support for Vitest v2.1.0+ (Sep 13 2024)

Wallaby has been updated to support the latest version of vitest, v2.1.0. This update was necessary due to breaking changes introduced in the latest vitest release.

Support for Vitest v2.0.5+ (Aug 01 2024)

Wallaby now supports the latest version of vitest (v2.0.5). The recent update of vitest included breaking changes that required updates to Wallaby's vitest integration.

Experimental node:test support (Jul 17 2024)

Wallaby now provides experimental support for the node native testing module, node:test (detailed in our docs). You can now use Wallaby with projects that use node:test, starting from Node v22.3.0 or higher. As this is an experimental feature, we anticipate there might be edge cases or unique configurations that could cause issues. We encourage you to report any issues or provide feedback so we can improve this integration.
