Feature settings

Toggle optional capabilities that extend what Test Companion can do, including checkpoints, notifications, and Electron testing support.

Feature settings lets you toggle optional capabilities that extend what Test Companion can do. Each feature here adds a specific type of functionality — workspace snapshots, desktop notifications, or Electron app testing support. You can enable or disable them independently based on your needs.

How to open Settings

1. Click the gear icon (⚙) in the top-right corner of the Test Companion panel.

   

2. Select the Feature Settings tab.

   

3. Make the necessary changes and click Save to apply them.
4. Click Cancel to discard any unsaved changes.

Enable Checkpoints

When checkpoints are enabled, Test Companion automatically creates a snapshot of your workspace files at important moments while it works on a task — for example, before modifying a file or before running a command that could change your project state. If the AI makes a change you are unhappy with, you can revert to an earlier checkpoint instead of manually undoing the changes.

Under the hood, checkpoints use Git to track workspace state. The extension creates lightweight commits behind the scenes to mark each checkpoint.

When to enable this

Checkpoints are valuable in most situations and are enabled by default. They are especially useful when:

• You are letting the AI work autonomously in Default interaction mode
• The AI is making changes across multiple files at once
• You are experimenting with different approaches and want to easily backtrack

When to disable this

There are specific cases where you may want to turn checkpoints off:

• Very large workspaces: If your repository is exceptionally large (for example, a monorepo with tens of thousands of files), the Git operations behind checkpoints can slow down. If you notice sluggish performance during tasks, try disabling checkpoints.
• Non-Git projects: If your workspace is not a Git repository and you do not want one to be initialized, disable this feature.

Enable Notifications

This is particularly useful when you start a task and then switch to another window or application while the AI works. Instead of periodically checking back, you receive a notification that brings you back to VS Code at exactly the right moment.

Example use case

You ask Test Companion to generate a full test suite for your user registration module. You switch to your browser to review the application’s UI while the AI works. A few minutes later, you receive a desktop notification: “Test Companion requires approval to proceed.” You switch back to VS Code and see that the AI wants to create a new file — you approve, and it continues.

When to enable this

• When you multitask and frequently switch away from VS Code while the AI is working
• When using Guided mode, where the AI pauses at each step for approval
• For long-running tasks where you want to be alerted upon completion

Enable Electron

Electron is a framework used to build cross-platform desktop applications with web technologies (HTML, CSS, JavaScript). Many popular applications, such as VS Code itself, Slack, and Figma, are built on Electron.

When this setting is enabled, Test Companion can understand and interact with Electron application structures, including:

• Testing VS Code extensions within the Extension Host
• Interacting with custom Electron app windows
• Analyzing Electron-specific APIs and IPC (inter-process communication) patterns
• Generating tests that account for Electron’s main process and renderer process architecture

When to enable this

• You are developing a VS Code extension and want to generate or debug tests for it
• You are building a desktop application using Electron and need testing assistance
• Your test automation needs to interact with Electron application windows

When to leave it disabled

If your testing work is limited to web applications and mobile apps (the most common use case), leave this disabled. Keeping it off avoids any unnecessary overhead or unintended Electron-related suggestions from the AI.
