nit: add a common.crashOnUnhandledRejection(); line here, and remove the .then(common.mustCall()) later.

@TimothyGu Thank you. As this is the first time I make a pull request I'm not very familiar with the these functions. You can add it later :)

@TimothyGu I added.

async function doTest() {
await assert.rejects(
async () => {
await import('../fixtures/es-module-loaders/throw-undefined');
},
(e) => e === undefined
);

Nit:

await assert.rejects(
  import('../fixtures/es-module-loaders/throw-undefined'),
  (e) => e === undefined);

The extra arrow function doesn't seem needed.

I just followed the example here:
https://github.com/nodejs/node/blob/master/doc/api/assert.md

You mean, the first parameter can be a promise (not a function)? I don't know, but I think mine is more formal :)
