Data Driven Test Development Demo

This is a simple demo that shows how to build a JWT-authenticated REST API from scratch by following a data-driven test development methodology. Let's run a few CRUD operations on the UK Premier League.

For further information please visit this post: A Data-Driven Test Development (DDTD) Approach with PHPUnit.

Start the Docker Services

docker-compose up --build

Install the Dependencies

docker exec -it --user 1000:1000 ddtd_demo_php_fpm composer install

Bootstrap the Testing Database

Copy and paste the following into your .env file:

DB_DRIVER=pdo_mysql
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=ddtd_demo
DB_USERNAME=root
DB_PASSWORD=password
DATABASE_URL=mysql://root:password@mysql:3306/ddtd_demo

Then run:

docker exec -it --user 1000:1000 ddtd_demo_php_fpm php bin/console database:bootstrap

Run the Tests

Copy and paste the following code into your phpunit.xml.dist file:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit
    backupGlobals="false"
    colors="true"
    bootstrap="vendor/autoload.php"
>
    <php>
        <env name="KERNEL_CLASS" value="App\Kernel" />
        <env name="APP_ENV" value="test"/>
        <env name="DATABASE_URL" value="mysql://root:password@mysql:3306/ddtd_demo"/>
        <env name="JWT_SECRET" value="example_secret_for_testing_only"/>
    </php>
    <testsuites>
        <testsuite name="auth">
            <directory>tests/auth</directory>
        </testsuite>
        <testsuite name="team/create">
            <directory>tests/team/create</directory>
        </testsuite>
        <testsuite name="team/update/{id}">
            <directory>tests/team/update/{id}</directory>
        </testsuite>
        <testsuite name="team/{season}">
            <directory>tests/team/{season}</directory>
        </testsuite>
        <testsuite name="team/delete/{id}">
            <directory>tests/team/delete/{id}</directory>
        </testsuite>
    </testsuites>
</phpunit>

Then run:

docker exec -it --user 1000:1000 ddtd_demo_php_fpm php bin/phpunit
