Setting up PHPUnit

With Flex it’s super easy to add PHPUnit to the project. Without further ado, let’s instruct the container do install the PHPUnit pack:

docker-compose exec php composer req --dev phpunit

That installed a bunch of libraries along with the PHPUnit. I don’t need the browser-kit and the css-selector and I’m going to ditch them:

docker-compose exec php composer rem symfony/browser-kit symfony/css-selector

The recipe for the PHPUnit pack added a number of additional files:

• the bin/phpunit script to execute tests
• phpunit.xml.dist base configuration file
• the tests directory with the bootstrap script

I have written some unit test already; let’s execute the suite:

docker-compose exec php bin/phpunit

That prints:

PHPUnit 9.5.23
