💻 Usage

👷 Adding a new solution

To create a new solution for day 28 do the following (replace 28 with the number of your day):

• Store the input in inputs/day28.txt.
• Create a new Solution for the day days/Day28/Solution.php That extends Styxit\AbstractSolution.
• Write the execute() method that writes the solution to $this->part1 and $this->part2.

In the Solution class, you can use $this->input to get access to the parsed input that belongs to that day.

Solve the puzzle with

 ./aoc solve 28

🐞 Testing

For each solution a test can be written to make sure the output is correct. by extending the AbstractDayTest only the Class to be tested + the solutions need to be defined. To test the solution for a new day, add a test in the tests/Days dir.

Run all tests:

./vendor/bin/phpunit --testdox tests
