How do I configure PHPUnit with Docker Compose?

To configure PHPUnit with Docker Compose, you'll need to set up a service in your docker-compose.yml file for your PHP application and include PHPUnit as a dependency.

Can you show me an example of a docker-compose.yml file for this?

Sure! Here's a basic example:

version: '3'
services:
  app:
    image: php:7.4-cli
    volumes:
      - .:/app
    working_dir: /app
    command: phpunit
    depends_on:
      - db
  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: test

What if I want to run tests automatically when I build the container?

You can add a command in your docker-compose.yml to run PHPUnit tests automatically. For example, replace command: phpunit with command: phpunit --testsuite=your_testsuite.

How do I install PHPUnit in the Docker container?

You can install PHPUnit by adding it to your Dockerfile. For example, use RUN composer require --dev phpunit/phpunit in your Dockerfile.
