#Rule Details

This rule reports imports of Node's test runner in Rstest test files, whether through an import declaration, a require() call, or an import ... = require(...) declaration, and whether the module is node:test itself or one of its sub-paths such as node:test/reporters. Such imports are commonly added accidentally by editor auto-import and select Node's test runner instead of Rstest.

Named imports of node:test containing only test, it, and describe can be safely fixed by changing the module to @rstest/core. Everything else is still reported, but is not fixed because the two modules do not have equivalent exports.

Examples of incorrect code for this rule:

import { test } from 'node:test';
import * as nodeTest from 'node:test';
import { mock } from 'node:test';
import { tap } from 'node:test/reporters';
const nodeTest = require('node:test');
import nodeTest = require('node:test');

Examples of correct code for this rule:

import { test } from '@rstest/core';
import { rs } from '@rstest/core';
const assert = require('node:assert');
