Expected Array but received array in Jest

Question

I created unit (async) test in Jest. But when I get response from server:

[
    {
        name: "My name"
    },
    {
        name: "Another name"
    }
]

and test it:

test('Response from server', () => {
    get('my-url').end(error, response) => {
        expect(response.body).toBe(expect.any(Array))
    }
})

some error occurs:

Comparing two different types of values. Expected Array but received array.

It's working when I use expect(response.body).any(Array). But is there any fix for expect.toBe()?

Answer 1

You should use toEqual (not toBe) to compare objects and arrays. Use toBe for scalar data types only. If you like to check the response data type use typeof operator
