Matching Regular Expressions with $httpBackend

Let's say you're doing unit testing like a good little developer and you're using Jasmine for it.  Let's further say you're testing Angular and you want to ensure that the correct URL is called on your service, but you don't necessarily care what parameters are passed, just that they're named correctly.  With the $httpBackend service you can match an endpoint using a regular expression so you don't have to worry about the actual values of the parameters.

Here's what I mean:

$httpBackend.whenGET(/Person\/GetById\?personId=.*&userId=.*&/).respond(200, []);

Any request that goes to [anything]Person/GetById?personId=[anything]&userId=[anything] will match and the $httpBackend service will return a 200 response with an empty array.

Works like a charm.
