This solution for the Howsy Code Challenge uses:

• PHP 8.1
• PHPUnit 9
• Mockery 1.5
• PHP DI 6.4
• Docker
• Docker Compose

1. Clone the repo.
2. Build the container. (this will also install composer dependencies)

docker-compose build

3. Run the container.

docker-compose up -d

4. Run the tests.

docker-compose exec app ./vendor/bin/phpunit --testdox tests

or

docker-compose exec app ./vendor/bin/phpunit tests

5. Run demo app.

docker-compose exec app docker-compose exec app php index.php

you can customize the contract period changing the variable $period in ./src/index.php:14

$period = 12;

6. Evaluate code! 😉
