prompt: Your task is to convert the following English description into an ASCII tree format.
  
  pages is a core directory that houses 3 subdirectories: api, nested-index and sub.
  In the root directory, 'api' shelters 1 folders: sub.
  In nested path 'api / sub', Inside 'sub', you'll find it appears to be unused.
  Back to the top level.
  In the root directory, 'nested-index' encompasses 1 folders: index.
  At level 2, in directory path 'nested-index > index', 'index' sits empty.
  Back to the top level.
  In the root directory, Inside 'sub', you'll find it is unpopulated.
  
  
  Format your response in this style:
  ```
  test
   +--env
   |   `--cypress
   |       `--e2e
   +--failing
   |   `--cypress
   |       `--e2e
   +--invalid
   |   `--cypress
   |       `--e2e
   `--successful
       `--cypress
           `--e2e
  ```
