Jasmine toEqual for complex objects (mixed with functions)

Question

Currently, I have a function that sometimes return an object with some functions inside. When using expect(...).toEqual({...}) it doesn\'t seem to match those c

Answer 1

If anyone is using node.js like myself, the following method is what I use in my Jasmine tests when I am only concerned with comparing the simple properties while ignoring all functions. This method requires json-stable-stringify which is used to sort the object properties prior to serializing.

Usage:

  var stringify = require('json-stable-stringify');

  var obj1 = {
    func: function() {
    },
    str1: 'str1 value',
    str2: 'str2 value',
    nest1: {
    nest2: {
        val1:'value 1',
        val2:'value 2',
        someOtherFunc: function() {
        }
      }
    }
  };

  var obj2 = {
    str2: 'str2 value',
    str1: 'str1 value',
    func: function() {
    },
    nest1: {
      nest2: {
        otherFunc: function() {
        },
        val2:'value 2',
        val1:'value 1'
      }
    }
  };

  it('should compare object properties', function () {
    expect(stringify(obj1)).toEqual(stringify(obj2));
  });
