Protractor: Scroll down

Question

I have an button on my page that is visible when the user scrolls down. Because of this, protractor tests give me an error:

UnknownError: unknown erro

Answer 1

I found that creating a util helper and using it inside page objects (or the test files themselves) helped. This seems to work well for me:

utils.js

module.exports = {
  scrollIntoView: function(el) {
    browser.executeScript(function(el) {
      el.scrollIntoView();
    }, el.getWebElement());
  }
}

inside page object somewhere...

var scrollIntoView = require('../utils').scrollIntoView;

module.exports = {
  clickBackBtn: function() {
    var el = element(by.buttonText('Go back'));
    scrollIntoView(el);
    el.click();
    return;
  }
}

in the test itself...

it('should allow the user to go back to the profile page', function() {
  PageObject.clickBackBtn();
  expect(browser.getCurrentUrl()).toContain('/user/profile');
});
