Install Test Companion in Visual Studio Code

Install Test Companion in Visual Studio Code, Cursor, or VSCodium to generate, automate, and fix test cases without leaving your editor.

You install Test Companion from the Extensions view, the same way you install any other Visual Studio Code extension. The same flow works in forks such as Cursor, VSCodium, and Kiro.

The setup process has three steps:

• Install the extension
• Verify the installation
• Sign in to your BrowserStack account

Prerequisites

Before you install the extension, make sure you have:

• A BrowserStack account. If you do not have one, create a BrowserStack account.
• Visual Studio Code 1.95.1 or later, or an equivalent version of Cursor, VSCodium, or Kiro.

To check your version, choose Code > About Visual Studio Code on macOS, or Help > About on Windows and Linux.

Install the extension

Your editor downloads the extension from the marketplace it already trusts, so you do not have to judge whether a .vsix file from another source is genuine. Use this path by default.

1. Open the Extensions view in your editor.
   • Keyboard shortcut: Ctrl+Shift+X on Windows and Linux, or Cmd+Shift+X on macOS.
   • Activity Bar: Click the Extensions icon.

   

2. In the search bar, type Test Companion.

   

3. Locate the Test Companion extension in the results list, published by BrowserStack.
4. Click Install.

Verify the installation

After the install completes, look for the Test Companion icon in the Activity Bar, the strip of icons along the edge of the editor window.

Click the icon to open the Test Companion panel.

If the icon does not appear, reload the editor window. Open the Command Palette with Ctrl+Shift+P on Windows and Linux, or Cmd+Shift+P on macOS, then run Developer: Reload Window.

Sign in to BrowserStack

Connect the extension to your BrowserStack account.

1. Click the Test Companion icon in the Activity Bar to open the Test Companion panel.

   

2. In the panel, click Sign in with BrowserStack.
3. Your default browser opens. It prompts you to authorize the extension.
4. Follow the prompts to sign in. If you do not have an account, create a BrowserStack account.

After you sign in, the browser returns you to your editor. The Test Companion panel then shows your user information.

Test Companion is installed and configured.
