  command is a source directory that includes 3 subdirectories: adapter, ci and export.
  In the root directory, 'adapter' has been left empty.
  In the root directory, 'ci' holds no subdirectories at the moment.
  At the top level, 'export' groups 1 folders: testdata.
  At level 2, in directory path 'export / testdata', 'testdata' houses 1 folders for testing purposes.
  At level 3, in directory path 'export → testdata → snapshots', The 'snapshots' data structure is an empty container.
