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

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

    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?

報告された deepEqual の失敗が発生する nodeunit/lib/types.js:83 から開始し、issue にある mongoose スキーマの例を再現します。比較された値がどのように表示されるかを追跡し、プロパティレベルの不一致についてどの情報が利用可能かを特定します。AssertionError が 2 つの完全なオブジェクトを出力するだけでなく、異なるプロパティまたは値を特定できれば完了です。
