Rspec::Generators::ScaffoldGenerator#mock_file_name

Returns the name of the mock. For example, if the file name is user,
it returns mock_user.

If a hash is given, it uses the hash key as the ORM method and the
value as response. So, for ActiveRecord and file name "User":

  mock_file_name(:save => true)
  #=> mock_user(:save => true)

If another ORM is being used and another method instead of save is
called, it will be the one used.
