     ENV_LOAD_ALL = True
     ENV_PREFIX = 'ROCKSTEADY_'

     BLAH = True
     TIMEOUT = 5
     POSTGRES_HOST = 'localhost'
     POSTGRES_PORT = 5432
     POSTGRES_USER = 'bebop'
     POSTGRES_PASS = 'secret'
     POSTGRES_DB = 'main'

     def SQLALCHEMY_DATABASE_URI(cls):
         return 'postgresql://{user}:{secret}@{host}:{port}/{database}?sslmode=require'.format(
             user=cls.POSTGRES_USER,
             secret=cls.POSTGRES_PASS,
             host=cls.POSTGRES_HOST,
             port=cls.POSTGRES_PORT,

         )

assert Config.TIMEOUT == 5
assert Config.BLAH is True
assert Config.SQLALCHEMY_DATABASE_URI == 'postgresql://bebop:secret@localhost:5432/main?sslmode=require'
try:
    Config.WHAT
