What's New (Page 8 of 9)

We made significant improvements to Show Value detection when using Show Value, Copy Value, and Debugger on selection. This update enables fuzzy token selection instead of previously having to select an exact token to output. In addition to being able to show values for additional syntax constructs, the feature also now has better support for code transpiled with TypeScript and Babel.

For VS Code and JetBrains editors, Wallaby now allows you to view any number of values (Show Value and Debugger on selection) without changing or editing your code. Inline values now survive code changes and are updated with their latest values, as you type. A few new commands are available, Clear Value (Escape), Clear File Values (Escape, Escape), and Clear All Values (clears values in all files).

For VS Code and JetBrains editors, Wallaby’s Time Travel Debugger now provides two additional commands to Run Back to Breakpoint and Run Forward to Breakpoint. Use your editor’s standard debugger breakpoints with these commands to improve your Wallaby debugging experience.

With the help of the Wallaby’s Test Profiler we’ve made incremental runs of Jest tests up to 5 times faster. The default create-react-app generated test takes Jest CLI runner ~430ms in watch mode to run, the same test takes Jest + Wallaby ~80ms.

Our first big feature of 2021 is expected to be a game changer for many of our users. The Test Profiler allows you to quickly and easily get the CPU Profile for any test. No configuration is required, one simple click and you will see the CPU profile for a test.

The first free Wallaby webinar was run on Wednesday, 14th October 2020. If you missed out, you may watch the webinar recording. The feedback from both new and existing Wallaby users was overwhelmingly positive with many saying they learned a number of new tips and tricks.

For VS Code and JetBrains editors, Wallaby’s new Test Story Viewer provides a unique and highly efficient way of debugging your code and inspecting what code your test is executing in a single logical view. The viewer is fully integrated with Wallaby’s Time Travel Debugger, which means you can simply select a variable or expression to see its runtime value. Having the executed code displayed in a single continuous view really cuts down on context switching that you may experience in a traditional debugger experience.

While not directly related to the Wallaby product, the Wallaby team created and released the Dingo VS Code extension that makes it easier to download, install and open git repos and the source code for npm packages, right from the comfort of your editor. The source code is available on GitHub under an MIT license and the extension is free for everyone to use.

If you are working in a larger project and only want to run a subset of tests, Wallaby’s new Exclusive Test Run feature for VS Code and JetBrains IDEs allows you to start Wallaby for a selected file or folder using the Start Exclusive Test Run command.
