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

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?

Comienza en nodeunit/lib/types.js:83, donde se produce el fallo de deepEqual indicado, y reproduce el ejemplo de esquema de mongoose del issue. Traza cómo se representan los valores comparados e identifica qué información está disponible para una discrepancia a nivel de propiedad. Se considera terminado cuando el AssertionError identifica la propiedad o el valor diferente, en lugar de imprimir únicamente los dos objetos completos.
