Checking object equality in Jasmine

Its the expected behavior, as two instances of an object are not the same in JavaScript.

function Money(amount, currency){
  this.amount = amount;
  this.currency = currency;

  this.sum = function (money){
    return new Money(200, "USD");
  }
}

var a = new Money(200, "USD")
var b = a.sum();

console.log(a == b) //false
console.log(a === b) //false

For a clean test you should write your own matcher that compares amount and currency:

beforeEach(function() {
  this.addMatchers({
    sameAmountOfMoney: function(expected) {
      return this.actual.currency == expected.currency && this.actual.amount == expected.amount;
    }
  });
});

I was looking for the same thing and found an existing way to do so without any custom code or matchers. Use toEqual().

If you're looking to compare partial objects, you might consider:

describe("jasmine.objectContaining", function() {
  var foo;

  beforeEach(function() {
    foo = {
      a: 1,
      b: 2,
      bar: "baz"
    };
  });

  it("matches objects with the expect key/value pairs", function() {
    expect(foo).toEqual(jasmine.objectContaining({
      bar: "baz"
    }));
  });
});
