prompt: Your task is to convert an English description into an ASCII tree format using this style:

  ```
  
  Convert this description:
  
  tests is a base directory that incorporates 4 subdirectories. Notable ones include helpers, regression, test262 among others.
  
  Let me break down the architecture for you:
  
  In the root directory, 'helpers' stores 1 child directories: browser.
  In nested path 'helpers > browser', The 'browser' storage space has yet to be populated.
  At the main level, 'regression' hosts 1 directories: libs.
  At level 2, in directory path 'regression → libs', 'libs' contains no subdirectories.
  At the main level, 'test262' organizes tests across 1 separate subdirectories.
  Within directory hierarchy 'test262 > test262', The 'test262' storage space appears to be unused.
  At the main level, 'unit' has 1 nested folders: fixtures.
  At level 2, in directory path 'unit / fixtures', The 'fixtures' data structure is devoid of content.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
