Description

im looking for more help in using the run method from node:test than what the online documentation shows. for example, how can i enable coverage reporting? what would be the way to do the equivalent of --experimental-test-coverage when using the run method? thanks.

Minimal Reproduction

import _process from "node:process"; import { run } from "node:test"; import { tap } from "node:test/reporters";

import { glob } from "glob";

async function testSrc(watch: boolean): Promise { const files = await glob( ["/*.test.ts", "*/.test.tsx", "/*.test.js", "*/.test.jsx"], { ignore: ["node_modules/", "build/"] }, );

await run({ files, watch, }) .on("test:coverage", (data:any) => { // this never fires console.log("test:coverage", { data }); }) .compose(tap) .pipe(_process.stdout); }

export default testSrc;
