prompt: Your task is to convert the following English description into an ASCII tree format.
  
  https-proxy is a master directory that comprises 2 subdirectories: lib and test.
  At the top level, 'lib' retains 1 subdirectories that organize the source code.
  Within directory hierarchy 'lib > util', The 'util' folder is barren.
  In the root directory, 'test' organizes tests across 3 separate contained folders.
  Within directory hierarchy 'test / helpers', 'helpers' stores 1 subdirectory elements: certs.
  At level 3, in directory path 'test / helpers / certs', 'certs' possesses 3 folders: ca, client, server.
  Within directory hierarchy 'test / helpers / certs / ca', The 'ca' storage space stands empty.
  In nested path 'test > helpers > certs > client', 'client' is vacant.
  At level 4, in directory path 'test / helpers / certs / server', Inside 'server', you'll find it contains no subdirectories.
  At level 2, in directory path 'test → integration', 'integration' contains no subdirectories.
  Within directory hierarchy 'test > unit', 'unit' stands empty.
  Back to the top level.
