[Bug]: Jest does not properly resolve href attributes with relative URLs

[elias6]

Version

27.1.1

Steps to reproduce

1. Clone my repo at https://github.com/elias6/jestAHrefTest
2. npm i
3. npm run test
4. You should see the bug.

Expected behavior

I expect the expect(link.href).toBe("https://example.com/"); line to pass.

Actual behavior

The line doesn't pass. I get this:

    Expected: "https://example.com/"
    Received: "http://localhost/"

Additional context

It seems that jest (or maybe jsdom) is not properly resolving the URL in the link's href attribute.

I tried setting the current URL using the top 3 answers to this question and none of them worked.

I also experience this bug in Jest 26.4.2.

Essentially jsdom/jsdom#1388 (comment), you cannot override window.location. You can use https://jestjs.io/docs/configuration#testurl-string

Hmm... right now I'm working around the problem by using a custom testEnvironment that puts the jsdom object in global, but I've been looking for a less awkward way to deal with this.

Is there any easy and practical way to make some tests use one testURL and other tests (in the same file) use a different one?

[SimenB]

https://jestjs.io/docs/configuration#projects-arraystring--projectconfig with separate configs should work

[elias6]

I looked at that projects thing, and it seems to be able to make all the tests in a given file use the same URL. But how can I set the URL to something different for each test or it call?
