assert.deepEqual does not seem to work correctly

Question

I want to test a serialize function of a nodejs module I've written.

In my tests I have the following strange behavior:

assert.equal(JSON.stringify(obj1), JSON.stringify(obj2)); // => TEST OK
assert.deepEqual(obj1, obj2); // => TEST FAILS

I have no clue what is going wrong here. The objects seem to look identical in my opinion.

obj1:

{
    "config": {
        "index_amount": 12,
        "ignore_case": true,
        "debug": false
    },
    "indexes": [{
        "p": [0, 1],
        "e": [0],
        "t": [0],
        "r": [0, 2],
        "a": [1, 2],
        "u": [1],
        "l": [1],
        "m": [2],
        "i": [2]
    }, {
        "pe": [0],
        "et": [0],
        "te": [0],
        "er": [0],

        "ma": [2],
        "ar": [2],
        "ri": [2],
        "ia": [2]
    }, {
        "pet": [0],
        "ete": [0],
        "ter": [0],
        "pau": [1],
        "aul": [1],
        "mar": [2],
        "ari": [2],
        "ria": [2]
    }, {
        "pete": [0],
        "eter": [0],
        "paul": [1],
        "mari": [2],
        "aria": [2]
    }, {
        "peter": [0],
        "maria": [2]
    }, {}, {}, {}, {}, {}, {}, {}],
    "data": ["Peter", "Paul", "Maria"],
    "data_ptr": 3,
    "free_slots": [],
    "single_data_counter": 3
}

obj2:

{
    "config": {
        "index_amount": 12,
        "ignore_case": true,
        "debug": false

        "u": [1],
        "l": [1],
        "m": [2],
        "i": [2]
    }, {
        "pe": [0],
        "et": [0],

        "er": [0],

Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers.

@thefourtheye postet them, but they are identical like I said — Frank Roth, Apr 29 '15 at 10:27
@FrankRoth I don't get any assertion error, when I do `assert.deepEqual(obj1, obj2, "Not matching");` — thefourtheye, Apr 29 '15 at 10:33
Therefore I posted my Prototype object. Maybe there are some differents in functions. But it was deleted... — Frank Roth, Apr 29 '15 at 10:39
i can see these are the json representation are you sure the original objects do not differ on any undefined properties? not 100% sure but if obj1 has a property set as undefined it wouldn't be represented in the json string but it would be taken into account for a deep equal — Dayan Moreno Leon, Dec 31 '16 at 08:13
