Set Viewport Size

[wurzelkuchen]

Quick Description

We are currently able to set the size of the browser window by using the .browserresolution flag in our config. For different browsers the same window size does mean a different viewport size, due to different window decorations.
It would be a nice to have to define the view port size directly to have a better comparison between browsers.

User Story

As a test automation engineer,
I want to configure my tests to have the same viewport size across different browsers
so that I can do a better comparison view.

Functional Requirements

• Add a property to define the viewport size directly for a browser
• Add a logic to set the viewport size, this will probably need the use of javascripts. See one example here
• Make sure browser window size (.browserresolution) and viewport size are not set both with different values. If this happens a usefull error should be thrown.

Documentation Requirements

• Add Documentation for this feature accordingly

Test Requirements

• Add unit tests
• Do a smoke test with an external test suite. Check also what happens in edge cases.
