Write a command that generates a metrics summary from a given file. Include some basic statistics: average, min, max, median; and if there were any under-performing periods of download.

These are some of the assumptions when implementing the solution:

• Extension of file is only json for now
• All metrics in the file have the same unit: bytes
• The expected stats metrics will have the same unit: megabits
• All metrics in the file contain sorted dates from oldest to newest
• All files contain successful requests with code ok
• The under-performing periods will be represented by a start and an end date

A list of TODOs was added to the TODO file in the project.

Make sure you set your env variables correctly in a .env file, especially including SUMMARY_OWNER and SUMMARY_VERSION. You can find example of their values defined in the phpunit.xml.dist file

Run the following commands from the project root:

docker-compose build

make resolve-dependencies

Make sure it worked by running the tests or one of the commands on the Makefile. i.e

make test

make analyse-file-one

make analyse-file-one-in-bytes

Run the command: make shell

We'll use only PHPUnit for testing. You can find the classes under ./tests.

For running all tests: make test
