How to check if an HTML5 validation was triggered using selenium?

Question

If testing my webapp using Selenium. All the form validation in the webapp is done using HTML5 form validations. Is there any way to assert if a form/input validation was tr

Answer 1

In addition to the answer from @Slanec: add also the following row (using C#, but it should be the same in Java or other languages):

Assert.IsTrue(true,"",elem1);

This is in case you want to check if the message is visible.
