fuzzy matching of response bodies

[timoxley]

Idea would be be able to be able to match partial responses ala component/to-function:

request(app)
.get('/users')
// don't care about other properties
// nor the exact details of timestamp property
// just that it exists and is numeric
.expect({ "timestamp":/\n+/}) 
.expect(200, done)

Also, if it were possible to just pass a sole function to expect, I could match however I wanted:

e.g.

.expect(function(res) {
  return _({ "timestamp":/\n+/})(res.body)
}) 
.expect(200, done)

I guess I could just do this in the final callback, but it'd be nice to be able to modularise the assertions:

.expect(hasTimestamp)
.expect(hasSpecialHeaders)
.expect(200, done)

+1 for this.

My expectation was that .expect would be fuzzy by default, both for modularizing assertions and ignoring fields which might not be predictable (e.g. a generated _id).

This would be very cool. Was just wondering whether I could do this.
