Using WebDriver and the power of jQuery to interact with html elements.

I was creating an automation test to verify that TeamMentor’s About page was displayed correctly. After opening the About page and perform the test, I wanted to close it (by looking at the small X  that closes the window).

But after some attempts to look at the element by class, I received an error. The Display attribute of the element was set to false (weird because it was displayed anyway). WebDriver throws an error when you are trying to perform any operation (like the click event) in an element that is not visible or the Display attribute is false.

Using the magic of jQuery to interact with those scenarios

Fortunately, I was able to find an approach to fire events (like click), using jQuery. This approach is quite interesting because I could think in a wrapper to execute a JavaScript code that contains some test. So this is the way to execute the jQuery:

JavaScript Executor

This method receives the jQuery script and executes it, which is really powerful. So at the time of invoking this method, you should pass your script, here is an example of how to use it:

jQuery script

The previous code uses jQuery to perform the raise the click event and close the window. Doing this with WebDriver (and trying to look at the element by class throws an error).

It seems like this is a good approach to be considered in the near future.
