Google Optimize test with universal Analytics

I'm using Google Optimize with Analytics (UA).
I've made a couple of simple tests with succes but now I'm a little clueless how make to following test:
On a category-page we have an overview of products. The case is that I would like to know if the click-throughs to a product-detail are the same if I remove the button... (image & title are still clickable).
If anyone can put me in the right direction how to test this, it would be highly appreciated! :)
BTW: it must be a/b test, not a multi-variation...
first in your variant code you can remove these buttons (if you are developer is easy with JS in Global JS).
Second you have to check if all links in the card are measured, when title, image or button are clicked must be send an event to Google Analytics.
Third, you have to use this event as primary goal, you can create a custom goal with its action, category and label.

Where you can find these values (in JSON format):
Which are the ones showed here:
So I think you don't need any ScrapyJS nor PhantomJS to scrape that information. Just understand where is it getting the information from and scrape the endpoint, directly.

Sitefinity - How to add link to internal page

I'm new to Sitefinity. So far I see some built in widgets to add image and text and let other edit them later on. However, I want to build a block which contains an image, a short description and when click that block will jump to an internal page. I'm stuck at figuring out how to make the internal URL editable.
Anybody has experience about this?
Thank you

Selenium cursor focus on field

I'm creating tests (in Firefox) for a web app.
Depending on what field the cursor is over, a different help screen will appear. But when creating tests for those help screens, i cant get Selenium to focus on the particular field i want.
I've tried using fireEvent, click, select, and type in order to get the focus to stay on the field i require in order to load that particular help screen but i've had no luck.
Does anyone have ideas on how this can be solved. Or how i can work around it?
You can use selenium2 AdvancedUserInteractions API:
Actions builder = new Actions(driver);
builder.moveToElement(someElement).build().perform();
if my understanding of your question is correct, you wanted to display different help screens for differnt elements,
o.k here it is, if the message of the screen is displayed as a tool tip and the styling is taken care by mouseover event
selenium.mouseOver(locator) and then [ Thread.sleep(1000) ] and then use
selenium.mouseOut(locator)
try with this.if you don't get it and if my understanding of your question is wrong please post it.
you must investigate how that screen is being is displayed. and try to post all that code
