How do I set up PHPUnit with Docker?

To set up PHPUnit with Docker, you need to create a Dockerfile and a docker-compose.yml file. Would you like a sample configuration?

Yes, please provide a sample Dockerfile and docker-compose.yml.

Here's a simple Dockerfile:

FROM php:8.0-cli
RUN apt-get update && apt-get install -y git unzip
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
RUN composer global require phpunit/phpunit
ENV PATH="/root/.composer/vendor/bin:$PATH"

And a sample docker-compose.yml:

version: '3'
services:
  phpunit:
    build: .
    volumes:
      - .:/app
    working_dir: /app
    command: phpunit

This will set up PHPUnit in a PHP Docker container.

How do I run my tests using this setup?

You can run your tests by executing the command docker-compose run phpunit in your terminal. This will start the container and run PHPUnit.

What if I want to run tests in a specific directory?

You can specify the directory by modifying the command to docker-compose run phpunit tests/YourTestDirectory. This will run tests located in that directory.
