Analyzing the values of two arrays of objects through unit testing

Imagine I have two similar arrays and I want to write unit tests to verify if these arrays contain the same values and if those values are equal. I am using mocha and enzyme for unit testing. What is the most effective approach to comparing these values?

const devices = [{
        deviceType: 'Tag',
        deviceId: 1,
        name: 'Tag For Sending and alarm',
        version: '',
        location: 'Room1',
        lastAliveMessage: '',
        deviceStatus: 'Active',
        actions: 'offline',

    },{
        deviceType: 'Tag1',
        deviceId: 2,
        name: 'Tag For Sending and alarm2 ',
        version: '',
        location: 'Room2',
        lastAliveMessage: '',
        deviceStatus: 'Active',
        actions: 'offline',
    }]

const devices2 = [{
        deviceType: 'Tag',
        deviceId: 1,
        name: 'Tag For Sending and alarm',
        version: '',
        location: 'Room1',
        lastAliveMessage: '',
        deviceStatus: 'Active',
        actions: 'offline',

    },{
        deviceType: 'Tag1',
        deviceId: 2,
        name: 'Tag For Sending and alarm2 ',
        version: '',
        location: 'Room2',
        lastAliveMessage: '',
        deviceStatus: 'Active',
        actions: 'offline',
    }]

 data.forEach(item => {
                devices.forEach(device =>{
item.deviceId.should.be.equal(device.deviceId))
                })
            })

Answer №1

When utilizing Chai, you have the ability to use Chai's deep.equal method to compare arrays of objects for similarity, regardless of the order of keys within the objects.

expect(devices).to.deep.equal(devices2)

Answer №2

Looping through each device in the devices array, we are checking if the deviceType and deviceId properties of each data item match the corresponding values in the device object.
