Let the browser choose the protocol

You should deliver all web content over https. In 2021 browsers are displaying increasingly obtrusive warnings when content is delivered over http.

Use protocol independent URLs whenever possible so that the browser will choose the protocol related to the protocol which the page is delivered with.

Example issues

  • When your page is delivered via https and you provide a youtube video only via http the most browsers (e.g. Firefox, Chrome) won't display the video.
  • When you deliver your youtube video via https://youtu.be/jyElDp98HdI your test which checks that the embeded video is rendered in the view will fail because your test server doesn't use https

Solution

Let your links look like //youtu.be/jyElDp98HdI and you will be fine, server side and test side.

Flaky tests are tests that sometimes fail for no obvious reason. They are the plague of many end-to-end (E2E) test suites that automate the browser through tools like Capybara and Selenium.

Join our free training event and learn to fix any flaky test suite, even in large legacy applications.
