Input on the English language:

In Danish we have a term called the "not test”, and we sometimes say about a political view, that it does not pass the not test, if no one would take the opposite view.

For instance, if a politician campaigns on wanting children to live happy lives, we may say, “it does not pass the not test", because no candidate is running on NOT wanting children to live happy lives.

Is there an established English term for such a "not test”?
