automatic tests - all the cases from demo

[piotr-s-brainhub]

We have already some tests but we need tests satisfying the following requirements:

• checking each demo case
• checking OS/ browsers (the newest version of browser and the newest version of OS):
  • Safari for Mac OS
  • Chrome for Mac OS
  • Edge for Windows
  • Chrome for Windows
  • Safari for iOS (iPhone and iPad)
  • Chrome for Android (Samsung Galaxy and Samsung Galaxy Tab)
• checking images size
• checking images/ thumbnails/ buttons location
• checking whether the image isn't cut
• checking whether the space for clicking is large enough which is important especially for mobile devices in order to be able to be touched with a finger
• checking animation speed
