Describe the feature you'd like

I am using Node's built-in test runner and I would like to use it with Datadog's Test Visibility feature.

The documentation doesn't seem to mention that this is supported. When I tried it I got an error. Reduced test case here. Contents inlined below:

package.json:

{
  "name": "lib",
  "private": true,
  "type": "module",
  "scripts": {
    "test": "NODE_OPTIONS=\"--require dd-trace/ci/init --import dd-trace/register.js\" node --experimental-strip-types --test"
  },
  "dependencies": {
    "dd-trace": "^5.40.0"
  }
}

foo.test.ts:

import assert from "node:assert/strict";
import { describe, it } from "node:test";

declare global {
  const foo: string;
}

describe("foo", () => {
  it("bar", () => {
    assert.strictEqual(1, 1);
  });
});

$ pnpm run test

hey @OliverJAsh ! Thanks for the request. We've been meaning to add support for node:test for a bit (it's indeed not supported), but haven't had the bandwidth to do it 😄. Your request is useful, as we can use it to add weight to the decision
