Modern node:test Explorer

VS Code Test Explorer integration for modern node:test projects.

Features

• Discovers tests statically without executing test files.
• Shows discovered tests in VS Code's Test Explorer.
• Adds editor run buttons for discovered tests.
• Runs tests with Node's native node --test runner.
• Supports native TypeScript execution in Node.js.

Requirements

• VS Code 1.100 or newer.
• Node 24 available to the extension for test execution.
• ESM test files.

Supported test files

The extension discovers tests in:

• *.test.js
• *.test.mjs
• *.test.ts
• *.test.mts
• *.spec.js
• *.spec.mjs
• *.spec.ts
• *.spec.mts

It intentionally supports only modern ESM node:test projects. CommonJS, legacy transpilers, compatibility loaders, TSX, and non-Node test frameworks are outside this extension's scope.

Node path

Test execution uses the vscode-node-test-explorer.nodePath setting and defaults to node from PATH.

If VS Code cannot resolve Node 24 from PATH, set an absolute path:

{
  "vscode-node-test-explorer.nodePath": "/path/to/node"
}

The extension does not discover or activate version managers.

Development

Use the local mise.toml:

mise trust
mise install
pnpm install
pnpm compile
pnpm package
pnpm package:pre-release
pnpm package:pre-release:all

Generated VSIX files are written under artifacts/vsix/.

mise.toml pins Node and pnpm and adds node_modules/.bin to PATH.

Publishing

pnpm publish:pre-release

Releasing

Update package.json and CHANGELOG.md, commit the changes, then run:

pnpm release:pre-release
