test.deepEqual gives AssertionError, without actual saying what property is not equal

[oveddan]

When test.deepEqual fails, we get a generic "AssertionError" message, without stating what property was mismatched. This requires you to scan the two objects to see what fails.

For example, I am trying a deepEqual test on two mongo schemas that seem to be exactly the same:

  var mongoose = require('mongoose'),
  ObjectId = mongoose.Schema.ObjectId;

  module.exports = {
    'deep equals works for mongooose schemas' : function(test){
      // SETUP/TEST
      var schemaA = new mongoose.Schema({keyA : String, keyB : ObjectId});
      var schemaB = new mongoose.Schema({keyA : String, keyB : ObjectId});
      // ASSERT
      test.deepEqual(schemaA, schemaB);
      test.done();
    }
  };

This gives me the following error when running the test:

✖ deep equals works for mongooose schemas

   { keyA:
      { enumValues: [],

    at Object.deepEqual (d:\Source\MySource\mongoose-strongly\tests\node_modules\nodeunit\lib\types.js:83:39)

A) I have to scan all the properties and try to see what's different, and B) the objects seem identical, what is actually different?

Recommend you using your favourite diff tool (mine is meld) to compare both results.
