Rstest

      • VS Code extension

      The Rstack VS Code extension keeps your project’s tests in sync inside the editor so you can browse, run, and debug them in VS Code. It covers the whole Rstack toolchain in a single install: testing, linting, and formatting.

      Installation

      You can visit the extension’s Visual Studio Code Marketplace page, or install it directly inside VS Code:

      • Open the Extensions view (Ctrl/⌘ + Shift + X) and search for rstack.rstack.
      • Open the Quick Open panel (Ctrl/⌘ + P), enter ext install rstack.rstack, and press Enter.
      • You can also run code --install-extension rstack.rstack in the terminal.

      For Cursor, Trae, VSCodium, and other VS Code forks, install it from the Open VSX Registry.

      Coming from the standalone Rstest extension

      The standalone rstack.rstest extension is retired and receives no new features. It stays published and keeps working while the transition is underway, but we recommend switching now:

      1. Install rstack.rstack as described above.
      2. Disable or uninstall rstack.rstest so only one copy of Rstest runs.
      3. Re-enter your settings under the rstack.rstest.* keys and re-bind any keybindings to the new rstack.rstest.* command ids. Settings are not migrated automatically. See the migration notes for details.
