#Configuration

  },
]);

#Rule Details

Disallows importing Node's test runner in an Rstest test file. Editor auto-import can otherwise select node:test instead of Rstest.

The rule reports static imports, require(), and TypeScript import = require forms for node:test and paths beneath it.

#Incorrect

import { test } from 'node:test';

test('creates a user', () => {});

#Correct

import { test } from '@rstest/core';

test('creates a user', () => {});

#Autofix

Changes an exact named import from node:test to an Rstest module when it imports only test, it, or describe.

The test API is reachable as both @rstest/core and rstack/test, and the fix writes whichever of the two the file already uses — in another import, a require, or a /// <reference types="..." /> directive — so that the rewritten import resolves in the project it was written for. A file that names both, or names neither, gets @rstest/core.
