RR7 way of testing actions and loaders

[otatar]

Hi there,

I have just migrated one of my web app from Remix v2 to React Router 7 (framework). Everything seems to work as expected, but I have problems with testing loaders and actions. Basic idea how to test loaders an actions in Remix I have found on this article/tutorial from Sergio:
https://sergiodxa.com/tutorials/test-remix-loaders-and-actions

But it doesn't hold anymore because loaders and actions in React Router 7 return:

DataWithResponseInit<{
    defaultValues: Partial<{}>;
}> | Response

So we cannot just use res.json() or res.status() or something like: expect(res).toBeInstanceOf(Response);

How to test it in RR7?

Thanks

Fabulous. I just started writing tests for something like this today. Really eager to see the discussion.

For context, I'm testing authentication code and I want to make sure it correctly throws or returns data and/or redirects.
