[TypeScript] Is there a cleaner way to assert that we are working with a SocialProfile in tests?

[beefchimi]

For all of our networks > tests, we have to use a typecast to assert what parseProfile is returning:

const {id, user} = mockSocialite.parseProfile(mockCommonUrl) as SocialProfile;

It would be great if we could somehow solve this from our mock:

// Calling `parseProfile()` will return a `SocialProfile`
const mockSocialite = new Socialite(allSocialNetworks);
