Ensure we have our mocked out ENV_AUTHORIZATION_FILE

  $ [[ $ENV_AUTHORIZATION_FILE[0,4] == '/tmp' ]] || return 1


Lets set a simple .env action

  $ mkdir sub
  $ cd sub
  $ echo 'echo ENTERED' >> .env
  $ echo 'echo LEFT' >> .env.leave

Change to the directory.

  $ _dotenv_read_answer() { echo 'y' }
  $ cd .
  Attempting to load unauthorized env file: /tmp/cramtests-??????/leave.t/sub/.env (glob)
  
  **********************************************
  
  echo ENTERED
  
  **********************************************
  
  Would you like to authorize it? [y/N] 
  ENTERED


Leave the directory and answer "no".

  $ _dotenv_read_answer() { echo 'n' }
  $ cd ..
  Attempting to load unauthorized env file: /tmp/cramtests-??????/leave.t/sub/.env.leave (glob)
  
  **********************************************
  
  echo LEFT
  
  **********************************************
  
  Would you like to authorize it? [y/N] 


  $ cd sub
  ENTERED
  $ _dotenv_read_answer() { echo 'y' }
  $ cd ..
  Attempting to load unauthorized env file: /tmp/cramtests-??????/leave.t/sub/.env.leave (glob)
  
  **********************************************
  
  echo LEFT
  
  **********************************************
  
  Would you like to authorize it? [y/N] 
  LEFT


Now check with subdirs, looking upwards.

  $ DOTENV_LOOK_UPWARDS=1
  $ mkdir sub/child
  $ cd sub/child
  ENTERED
  $ cd .
  $ cd ..
  $ cd ..
  LEFT


Now check with subdirs, not looking at parent dirs.

  $ DOTENV_LOOK_UPWARDS=0
  $ cd sub/child
  $ cd ..
  ENTERED
  $ cd child
  $ cd ../..
  LEFT
