Enhanced GUI test development tool to reuse StepMaker controls

[pevogam]

The extensions planned for the current GUI test development tools are meant to make it completely replace the StepMaker tool. In particular, it should have:

• vnc screen built in the same window as the controls for states and coding ("gameboy" design like in the StepMaker editor or virtmanager)
• mouse and keyboard recording of position, motion, clicking, key codes, clearing of key codes
• adding sleep control (saving a sleep N seconds step when needed)
• screen regions selection (using the mouse) and conversion to needles (final visual files) to replace the general "screenshot" buttom
• timeout setting (automatic on pause) and time of the displayed screendump

For more information you can follow our previous tutorials replacing "type = stepmaker" in a misX install test and analyze the gtk controls of the stepmaker tool.

The tool has been refreshed for parallel and up-to-date support but it still needs deeper dive into these features.

I am attaching a screenshot of the original StepMaker interface which can be used as a source of inspiration on how we should arrange the potentially extended devtool GUI controls.

Corresponding branch that this could build further on at the time of posting is imglogs-improvements. We have to start with Pyro5 and external snapshot support, not to mention that we don't have a proper parallel subcontainer support.
