In some case you want to add/remove an attribute or otherwise intentionally change the HTML output, and if that output is covered by parser tests those tests need to be updated. When updating parser test cases it's easy enough to tell the difference between intentional and accidental changes, but this is not so apparent when comparing pre- and post-change parses of big wiki pages (like when Tim added class="mw-redirect" to all links to redirects, which cluttered Special:ParserDiffTest output).

Instead of throwing a huge amount of wikitext at it and hoping that'll cover everything, we should make our test suite more comprehensive by adding lots of new parser test. Of course there'll be *some* crazy bugs concerning weird interactions that only happen in the wild, you can't really write tests for those, but that's life.
