We have tests for "new Intl.Collator()", including "shouldBe("new Intl.Collator().compare.call(null, 'a', 'b')", "-1")". We can test that because any sensible language will likely have 'a' before 'b'. It can still be wrong, but it's extremely unlikely.
Testing compare('a', 'A') with an unknown locale is harder to predict. If we do really want to test it, we could do
shouldBeTrue("var collator = new Intl.Collator(); collator.resolvedOptions().locale != 'en-US' || collator.compare.call(Intl.Collator('en', { sensitivity:'base' }), 'A', 'a') == 1");
But that's not the point of this test case, if you look at the comment above it. The point of this test case is to test that calling compare() with any "this" has no effect on it.</pre>
