Aftermath: Renovation of Test generation

[wadoon]

Remaining action items for the test case generation:

• Worked on command line and I could now also find the directory. It was in my home directory (so it seems the GUI info is ignored?)
• Maybe we should place it in the directory where it is called by default?

• Check if options are available for the output path.

Thanks!
