Downloads puzzle inputs for Advent of Code and synthesizes PyTest fixtures

Project description


This pytest plugin downloads puzzle inputs for [Advent of Code][1] and synthesizes fixtures that you can use in your tests.


Installing and configuring

Installing is easy: pip install pytest-aoc. Next you will need to configure two things: for which event (year) the plugin should download inputs, and a valid session cookie. These are normally valid for about a month or so.

To set the year, put it in setup.cfg:

aoc_year = 2018

Then, put a valid session ID in a file named .cookie and also name this file in your .gitignore.

With these two things in place, when running pytest, this plugin will download any missing inputs, and generate pytest fixtures that you can use in your test functions, see 'Using' and 'Fixtures', below.


With this plugin properly configured, you can write tests like this:

def test_01a(day01_numbers):
    assert sum(day01_numbers) == 123

Here, the parameter day01_numbers is a fixture that contains the numbers on each line in the file input/day01.txt.


These fixtures are synthesized for each available day. They're not executed until you ask for them in a test.

  • dayNN_text: The text in the input file, but stripped of any leading and trailing whitespace.
  • dayNN_raw: The raw text in the input file.
  • dayNN_lines: A list of lines.
  • dayNN_numbers: A list of numbers.
  • dayNN_number: A single number.
  • dayNN_grid: A list of lists, representing a grid of textual values.
  • dayNN_number_grid: A list of lists, representing a grid of numbers.

Command-line and configuration options

You can pass the options from the command line or set them in setup.cfg. The command line takes precedence.

  • --aoc-year/aoc_year: The year for which to download puzzle inputs. (Mandatory)
  • --aoc-session-id/aoc_session_id: The session ID to use for requesting puzzle inputs. (Optional)
  • --aoc-session-file/aoc_session_file: The file from which to read the session ID. (Optional; default .cookie)
  • --aoc-input-dir/aoc_input_dir: The directory in which inputs are stored. Will be created if it doesn't exist. (Optional; default input)
