What's New (Page 5 of 7)

Wallaby for VS Code provides a new setting to control where the diff view is opened. The default is to open the diff view in the first view column. You may instead configure diff views to open in the active (current) view column or beside the current view column.

Wallaby’s new interactive tutorial is ideal for showing new users how to use Wallaby. The tutorial may also be used by existing users who want to learn how to use new features when they become available.

Wallaby now supports VS Code’s built-in Test Explorer. The new Test Explorer UI shows all of the tests run by Wallaby and is updated in real-time and with context menu actions to quickly access relevant Wallaby commands.

Wallaby now has a new Jump to Line Test command in VS Code, and an intention action with the same name in JetBrains editors. When you run the command, Wallaby will show you the list of tests that are covering the line. You may quickly pick a test from the list and navigate to it.

Wallaby now displays more error details (and corresponding actions) such as stack with code context in editor hover tooltips in VS Code. Simply move your mouse over a line of code with an error, or use VS Code Show Hover command on the line, and you will see the error details.

As of Jest 27, jest’s default test runner was changed from jest-jasmine to jest-circus (which is meant to improve error messages, maintainability, and extensibility). Previously Wallaby always used jest-jasmine as the test runner when running tests in Jest regardless of what was configured. Wallaby now supports uses jest-circus when it is configured for your project.

The latest version of Mocha v9 was released on June 8th 2021 and had a number of breaking changes to Wallaby / Mocha integration. Wallaby now supports the latest version of Mocha v9.

Angular v12 included a number of significant breaking changes that required updates to Wallaby’s Angular integration. The latest version of Wallaby now fully supports Angular CLI v12.

The next major version of Jest was released on May 25, 2021. The changes in this major version release required significant updates to Wallaby’s Jest integration, which we had been working on for a number of months with Jest’s beta releases. We were pleased to be able to release support for Jest v27 within a day after it was released.
