Run composer install to get dependencies.
Alternatively, you can install dependencies using docker with docker-compose run --rm php composer install.
You can run tests with PhpUnit using ./vendor/bin/phpunit.
If you prefer using docker you can run tests with docker-compose run --rm php ./vendor/bin/phpunit.
A Test Run Logger is installed and logs all test runs. At the end of the kata you can take a moment to review the logs and see if you see strange patterns. To make it easier to review you can write the time when you're entering or leaving a refactoring phase, or when you're facing difficulties. If you see something weird, what could have you done differently to avoid it?
TCR stands for test && commit || revert. When tests are passing the code is automatically committed, otherwise it's reverted.
Its a good training for writing really small increments of code.
A TCR script is included in this repo and you can use with ./tcr.
The script is a relaxed variant of TCR, the tests aren't reverted.
