Well, here's the way I see it: Extensions (including ext/intl) declare their API and tests are made againt this API. No more and no less. If, for example, some error-text comes directly from underlying library and extension doesn't have control over it it shouldn't be part of API. In this case we can test that "some error-text was returned" but we shouldn't test for exact text-match
