What's New

Smart Start

15 Mar 2022

Wallaby’s new Smart Start feature allows you to quickly start Wallaby and only the test file(s) that you are currently working on will be executed. As soon as you open another test file, Wallaby will automatically run those tests and Wallaby will continue to execute those tests when they are affected by your code changes. Smart Start can be configured to always run a set of test files on start, and you can customize the automatic test execution behavior to run on edit (instead of open), or to never run automatically.

Resolve getters during logging

11 Mar 2022

Automatically expanded objects (logged with the special comment //?+) now resolve property getters. So in case of  const a = { get b() { return 1; } }; //?+  the output will be { b: 1 }. If you want to always resolve property getters regardless whether the logged object is automatically expanded or not, you may use the new resolveGetters configuration setting.


HTML output from tests is highlighted using your editor theme and colors

09 Mar 2022

Wallaby now highlights HTML output for logs and Testing Library errors. Unlike the ANSI colored output in your editor terminal test run results or basic built-in test output support, Wallaby output is highlighted using your editor theme, so all color settings are under your full control.


Time Travel Debugger now displays console logs, live comments and identifier expressions

25 Nov 2021

Time Travel Debugger now displays console logs, live comments and identifier expressions. Previously Wallaby debugger was hiding the logs (to inspect runtime values during time-travel debug sessions you need to select the expression or variable that you want to view). Now when the currently debugged line is a console log, a line with a live comment, or an identifier expression, then the current value gets logged and is available for inspection inline as well as in Value Explorer and Output Inspector.

Information is displayed in a code editor window, providing rich keyboard support and allowing you to stay in your coding mindset so that you don’t lose your flow.

Wallaby App - Improved Automatic Test Selection

23 Sep 2021

VS Code Open Diff Setting

17 Sep 2021

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.
