Installation guide

Install Test Companion in your IDE to generate, automate, and fix test cases without leaving your editor.

Test Companion runs as an extension or plugin inside your editor. Choose the install guide that matches your IDE.

Visual Studio Code and forks

If you use Visual Studio Code, Cursor, VSCodium, or Kiro, follow the Visual Studio Code install guide. One flow covers the editor and its forks, because they share the same Extensions view.
