Hi there,

In this newsletter we recap on the key new features that we released in late 2019 through to February 2020.

Time Travel Debugger (for VS Code and JetBrains IDEs)

Wallaby’s Time Travel Debugger allows you to move forward and backwards through your code to understand the conditions that led to a specific bug. The Time Travel Debugger accelerates your edit, compile and debug loop by allowing you to jump to a specific line of code, view runtime values, edit-and-continue and step into, over and out of your code.

Wallaby's Time Travel Debugger is available for VS Code (released December 12, 2019) and JetBrains IDEs (released February 5, 2020).

Test Filtering

Wallaby's Test Filtering feature allows you to limit the display of inline code coverage indicators and inline run-time values to only the test(s) that you are working on instead of all tests in your project. A new Toggle Test Filter command allows you to switch focus between individual tests and their execution results instantly. Filter selection can be toggled via your editor (code actions and intention actions) as well as within Wallaby App.

Object Proxy Logging

Our new Object Proxy feature allows you to wrap any selected object value with JavaScript Proxy to quickly see where the object's properties are being accessed from and what values are returned/set, as well as where the wrapped object functions are used and what values they return.

Jump To Test (for VS Code and JetBrains IDEs)

Wallaby's new "Jump To Test" command for VS Code and JetBrains IDEs allows you to quickly search and navigate to a specific test. It's now even easier to navigate through your tests without leaving your editor.

Value Explorer Call Stack (for VS Code and JetBrains IDEs)

Wallaby's Value Explorer has a handy new feature that allows you to view and navigate the full call stack of logged values. For any logged value, inspect its call stack by expanding the Call Stack node under the logged value’s node.

Interactive Examples for Quokka VS Code

Have you ever forgotten how to use Array.splice() or some other seemingly basic built-in JavaScript function?... we have

You can now use interactive JavaScript examples without leaving VS Code with Quokka.js! This feature is available for both 'Community' and 'Pro' edition users. We will be adding to our curated JavaScript examples over the coming months (it's free for everyone to use under CC0-1.0); feel free to contribute.
