About bucket.mutateIn's Mock and tests

Node.js SDK
1

Hello,

We are currently switching from document’s full save to mutateIn calls.
It’s great feature but the mock function is not implemented yet:

var couchbase = require('couchbase').Mock;
var db = new couchbase.Cluster();
var bucket = cluster.openBucket();

//bucket.mutateIn() does not exist

This problem has already been talked about here.

As @brett19 said i would gladly implement it via a PR but I can’t find any test cases for the mutatin function.

If I missed the tests for mutateIn function can you please help me find them ?
If I there is no tests for it can you provide them so we can implement the mock function ?

Cheers
