How to catch ngToast in protractor?

Question

Angular

Unable to test ngToast popup. Who does it how? My code:

var HomePage = require('./home.pageObject');

describe('Home Page tests', function () {
    var homePage = new HomePage();
    var EC = protractor.ExpectedConditions;

    beforeEach(function () {
        browser.get('/#/');
    });

    it('should fail login', function () {
        var toast = $('.ng-toast');
        homePage.signinBtn.click();
        homePage.login('admin', 'Password')
            .then(function () {
                var toast = $('.alert');
                browser.wait(EC.visibilityOf(toast), 3000);
            });
    });
});
