I have used Laravel Sail (Docker) while working on this code. Coding has been done with TDD of the methods implemented for adding person or spouse.

• Clone the repo in your local.
• Paste the .env file from the email into the project's root directory.
• Install the composer dependencies:

docker run --rm \
    -u "$(id -u):$(id -g)" \
    -v $(pwd):/var/www/html \
    -w /var/www/html \
    laravelsail/php81-composer:latest \
    composer install --ignore-platform-reqs

• On the Terminal inside the project directory run the following:

sail up -d [Make sure docker is installed and running] or ./vendor/bin/sail up -d (if sail is not set as an alias)

Family tree data of King Arthur & Queen Margret has been added to a seed file (FamilyTreeSeeder) which will be used to initialize the basic family tree to work with.

sail artisan migrate --seed

This will install and boot up all necessary packages to run the application along with the PHPUnit Test Suit.

Unit tests have been implement to test the critical functions of the Person class. To run the test suit simply execute the below command:

sail test

Database for Tests is called 'testing' where all the test operations are executed and its separate from the apps main database which is named as family_tree. (All automatically setup when running the sail up -d command)

sail test --coverage (xDebug is already enabled in .env for this feature to work)

Current code coverage for the test suit is 73.1%

Please add the inputfile.txt into storage/app directory (sending in email).

I have added a console command to process this file and give an output on console.

sail artisan FamilyTree:run

There can be some refactoring and additional functionaly added to make the code more robust. I have tried to just cover the basics here.
