Crawl rules unit tests
As your set of crawl rules grows, it gets increasingly complicated to understand exactly which URLs are included or excluded. In Central Admin we can test all rules by pasting in a single, example URL. We then see which rule is trigged and what the outcome is (include or exclude).
I'm asking for this functionality to be expanded. I would like to define a set of unit tests that we can run against our crawl rules list. The unit test can be defined as simple as a list of URLs where the outcome is either include or exclude.
You can then maintain your list of crawl rules with confidence. If someone adds a crawl rule with good intentions (but dire consequences) - you should immediately see that the rule breaks one of the previously defined unit tests.
