Load module from browser field package.json with WTR

[ranile]

I have a library which loads different modules for node and browser using main and browser fields of package.json. I would like to resolve to the browser field when importing the library:

import { fn } from '..'

// fn should come from `browser` module

How do I do so with web test runner? I don't see anything in documentation regarding it.

Note that I'm hoping to use the same test files with both jest and web test runner to test node and browser modules, so keeping that possibility would be helpful
