Chai deep equal not working

I'm trying to use Chai, but I cannot get the deep equal comparison to work for some reason.

This is a minimum example

var chai = require('chai');
var expect = chai.expect;
...


expect({
    test: {a:2}
    }).to.have.deep.property('test', {a:2});

That generates this output

AssertionError: expected { test: { a: 2 } } to have a deep property 'test' of { a: 2 }, but got { a: 2 }

I'm using Chai 3.5.0 and would expect this assertion to be true.

For version 4.0.0 they have changed behavior of '.have.deep' You can see release notes here

chai releases 4.0.0

I suggest you to update chai if it is possible.

You have to upgrade to a newer version of Chai. This feature was introduced in Chai 4, see 4.x.x Complete Migration Guide.
