Add Hover Support for Interaction Testing#100

Sometimes, we need to test how users use :hover to engage with a desktop product, or user :hover effects to make the expereince feel more realistic.

USE CASE 01: TOOL TIPS:
Being able to simulare tool tips when overing an object would be useful to see if users rely on tips to make a decision.

USER CASE 02:
Show highlight effects in dropdown menus when hovering over an options, so that we don’t have to put in a static click step to show the effect. Click menu > options appear > hover over options = highlight effect (RGBA, or various PNG uploads for each item for example) > Click item they are hovering.

USE CASE 03:
Button states cannot be tested as it is now - hovr, focus, pressed, etc.
