Testing Equality in Unit Tests: Comparing Objects and Arrays

Forgive me for this seemingly silly question, but I'm having trouble understanding it. I am a newcomer to both testing and JavaScript, so please bear with me.

Here is the test in question:

describe('initialized from copy job functionality', () => {
    it('should initialize the constructor based on production selection', () => {
        spyOn(MockWizardService, 'loadViewsForWizardSteps').and.returnValue(q.resolve({
                templates
        }));
        controller.Init();
        scope.$digest();
        expect(controller.templatesToBeDisplayed).toEqual(templatesAll);
    });

These are the template arrays being used:

let templates = [
    'views/wizards/create_test/sortStep.html',
];
let templatesAll = [
    'views/wizards/create_test/general.html',
    templates,
    'views/wizards/create_test/summary.html'
];

The value of templates may change, which is why it is structured in that way. Below is the error message I am encountering:

Expected $[1] = Object({templates: [ 'views/wizards/create_test/sortStep.html' ] }) to equal [ 'views/wizards/create_test/sortStep.html' ].

I realize that I need to modify the structure of templates within templatesAll, but I can't seem to figure out how to do it.

Answer №1

Is there a way to resolve this issue by modifying the expect statement?

expect(controller.templatesToBeDisplayed.templates).toEqual(templatesAll)

You might want to consider providing more details in your question. Have you observed that it returns an object with an array named templates? Your test lacks clarity due to the complexity hidden within the controller. It could be beneficial to focus on testing smaller functions and sharing the code for better assistance.

Best of luck in resolving this issue :)
