      when setting up tests. Please refer to the wiki.
  
      Parameters
      ----------
      scene_object : :class:`~.Scene`
          The scene with which we want to set up a new test.
      module_name : :class:`str`
          The name of the module in which the functionality tested is contained. For example, ``Write`` is contained in the module ``creation``. This will be used in the folder architecture
          of ``/tests_data``.
  
      Examples
      --------
      Normal usage::
