Test if method removes a list item (Jasmine)

I have a method in a service that removes items over 60 days from a list.

self.removerAntigas = function () {
        var dataCorte = new Date();
        var dataAux = dataCorte.getDate();
        dataCorte.setDate(dataAux - 60);
        itens.forEach(function (item) {
            if (item.data <= dataCorte) {
                itens.splice (itens.indexOf(item),1);
            }
        });
    };

I also have the method that obtains all items from that list: 

self.obterTodos = function (){
    return itens;
}

And the method add: 

self.adicionar = function () {
    var item = {
        data: new Date(),
        latitude: 0,
        longitude: 0,
        conectado: true,
        sincronizado: false
    };
    itens.push(item);
};

How can I write a test using Jasmine that tells me if I have removed the correct items from this list?

There’s some code missing from the question, it’s not clear where the itens. But I’ll give you an example with this in time of itens that from what I read in the code I think that’s what you want.

describe('removerAntigas', function () {

    it("should add new item", function () {
        window.itens = [gerador(), gerador(), gerador()];
        window.adicionar()
        expect(window.itens.length).toEqual(4);
    });
    it("should return all items", function () {
        expect(window.obterTodos()).toEqual(window.itens);
    });
    it("should return all items", function () {
        expect(window.itens.length == 4).toBeTruthy();
        window.removerAntigas();
        expect(window.itens.length < 4).not.toBeTruthy();
    });
});

  • But in this case, I need to call the add by creating a fake list. With dates you would need to remove and dates you don’t need. My add already creates the "date" object with new Date(), in which case I want to pass the dates for it to create the list. This list comes from the service, it is manipulated directly there and does not contain items.

  • @Julianaprado in a test you must always have some list. As you did not give an example I created a fake. If you have a better example. Put here that I integrate or adapt the use of the code I gave...
