expect(new Error).to.be.an('error') does not work

[egebircan]

it('test case', () => { expect(new Error).to.be.an('error'); })

When the code above is executed, "AssertionError: expected [Error] to be an error" is thrown.

According to the docs this behavior is not natural.

The code you wrote @egebircan works for me.

You are right @martineizayaga. I tested it again and it works. I guess there was some kind of an environment issue on my local machine at that moment. Thanks for pointing out.
