Is it possible to use rescue with a conditional?

Consider a Rack app. I only want to handle the error if we are not running a test:

begin
  do_something

  if ENV[ 'RACK_ENV' ] != 'test'
    rescue => error
      handle_error error
    end
  end
end

This generates syntax error, unexpected keyword_rescue (SyntaxError) rescue => error

Is there a way to do this?

Solution

  • Could you do something like this?

    begin
  do_something

rescue => error
  if ENV["RACK_ENV"] == "test"
    raise error
  else
    handle_error error
  end
end

    This would re-throw the exception if you are not testing.

    EDIT

    As @Max points out, you can be a little more succinct with this.

    begin
  do_something

rescue => error
  raise if ENV["RACK_ENV"] == "test"

  handle_error error
end
