The What’s New section includes major features and changes that have been made in the last 12-18 months. For older news or more details about minor updates and changes, please refer to our changelog.
Introducing Wallaby v3 (Sep 26 2025)
We're proud to introduce Wallaby v3, an overhauled engine that streams test, coverage, log, and error results in real time. Wallaby v3 starts instantly with cached results, prioritizes execution of the files you’re working on, and keeps you updated with progress and time estimates. Read more in our blog.
Test Explorer in Overview panel (Sep 23 2025)
The Wallaby overview panel now lets you toggle between a list of failing tests and the full test tree. The same actions and keyboard shortcuts work in both views.
Coverage View Improvements (Sep 11 2025)
Wallaby's Coverage view is now automatically filtered based on smart start, selected or focused tests. This makes it easy to concentrate on relevant parts of your project and avoid noise from unrelated or uncovered files.
Log Copying Improvements (Aug 14 2025)
Wallaby Logs now provide a convenient way to copy values and paths from log entries. This feature allows both root level and nested values to be quickly copied or identified. This is particularly useful when working with object hierarchies and array elements. These new copy actions are available through keyboard shortcuts and a new context menu.
VS Code Coverage Improvements (Jul 31 2025)
Wallaby for VS Code now shows file-level code coverage directly in the Explorer View and the Test Coverage View. This makes it easier to spot what's covered (and what isn't) at a glance.
Angular v20 support (Jul 25 2025)
Angular CLI v20 introduces a significant update: esbuild is now the default build system, replacing webpack. Wallaby now fully supports Angular CLI v20, enabling seamless testing for projects using either @angular/build:karma or legacy @angular-devkit/build-angular:karma configurations.
