Special:AbuseFilter/test is great because it lets us make sure that the testing pattern won't cause a mayhem by testing against recent edits.

However, in addition to that, it would be useful to have an ability to test against log entries (Special:AbuseLog&wpSearchFilter=...), to make sure that

• the testing pattern still catches stuff that was caught before
• the testing pattern successfully avoids known false positives

Currently, we kinda have the ability to do this already via Special:AbuseFilter/examine/log/..., but we need to do this for each log entry. I believe having a batch test just like Special:AbuseFilter/test would be very useful.
