Step-by-step tutorial how to prepare Symfony bundle

Prepare repository

Prepare bundle repository in the way you like. You can use Github or local repository. Be advised that repository need to be accessible by your future project.
With Github wizard you can add README.md and LICENSE
Github repository wizard

Clone repository

git clone https://github.com/kjonski/how-to-bundle.git

and open with editor.

Add composer.json file

{
    "name": "kjonski/how-to-bundle",
    "type": "symfony-bundle",
    "description": "Step-by-step Symfony bundle tutorial",
    "keywords": ["php", "symfony", "reusable bundle", "tutorial"],
    "license": "MIT",
    "authors": [
        {
            "name": "Karol Jonski",
            "email": "kjonski@pgs-soft.com"
        }
    ]
}

commit and push changes.

Configure project's repository

If you want develop bundle inside existing project and unless bundle isn't in packagist.org please configure main project's composer.json. Add/modify repositories section:

"repositories": [
    {
        "type": "git",
        "url": "https://github.com/kjonski/how-to-bundle.git"
    }
],

when using Github repository, or:

"repositories": [
    {
        "type": "git",
        "url": "/path/to/how-to-bundle.git"
    }
],

when using local repository. For more details @see Composer documentation.

Install you bundle with composer

$ composer require kjonski/how-to-bundle

Prepare structure

b$ means vendor/yourVendorName/yourBundle (vendor/kjonski/how-to-bundle) directory.

b$ mkdir src
b$ mkdir tests

Configure autoloading in your composer.json

"autoload": {
    "psr-4": { "Kjonski\\HowToBundle\\": "src/" }
},
"autoload-dev": {
    "psr-4": {
        "Kjonski\\HowToBundle\\Tests\\": "tests/"
    }
}

Install dependencies

b$ composer require symfony/dependency-injection
b$ composer require --dev symfony/http-kernel
b$ composer require --dev phpunit/phpunit

Add bundle class

<?php
// src/KjonskiHowToBundle.php

namespace Kjonski\HowToBundle;


use Symfony\Component\HttpKernel\Bundle\Bundle;

class KjonskiHowToBundle extends Bundle
{

}

Add extension class

<?php
// src/DependencyInjection/KjonskiHowToExtension.php

namespace Kjonski\HowToBundle\DependencyInjection;


use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;

class KjonskiHowToExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
    }
}

Prepare first test

<?php
// tests/KjonskiHowToBundleTest.php


namespace Kjonski\HowToBundle\Tests;


use Kjonski\HowToBundle\DependencyInjection\KjonskiHowToExtension;
use Kjonski\HowToBundle\KjonskiHowToBundle;
use PHPUnit\Framework\TestCase;

class KjonskiHowToBundleTest extends TestCase
{
    public function testGetContainerExtension(): void
    {
        $bundle = new KjonskiHowToBundle();
        $this->assertInstanceOf(KjonskiHowToExtension::class, $bundle->getContainerExtension());
    }
}

and run from bundle directory:

b$ vendor/bin/phpunit tests

At any point of time from now you can:

$ composer remove kjonski/how-to-bundle

and

$ composer require kjonski/how-to-bundle

and your bundle will be reinstaled.
Be advised that you need to run:

b$ composer install

to install your dev dependencies.

Add tests configuration (tests/phpunit.xml)

<?xml version="1.0" encoding="UTF-8"?>

<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/7.0/phpunit.xsd"
         backupGlobals='false'
         backupStaticAttributes='false'
         beStrictAboutTestsThatDoNotTestAnything='true'
         bootstrap='./../vendor/autoload.php'
         colors='true'
         convertErrorsToExceptions='true'
         convertNoticesToExceptions='true'
         convertWarningsToExceptions='true'
         stopOnError='false'
         stopOnFailure='false'
         stopOnIncomplete='false'
         stopOnSkipped='false'
         verbose='true'
>
    <php>
        <ini name="error_reporting" value="-1" />
        <env name="KERNEL_CLASS" value="\Kjonski\HowToBundle\Tests\App\AppKernel" />
        <ini name='display_errors' value='1' />
        <ini name='display_startup_errors' value='1' />
        <ini name='error_reporting' value='-1' />
        <ini name='memory_limit' value='-1' />
    </php>

    <testsuites>
        <testsuite name="How To Bundle Test Suite">
            <directory>.</directory>
        </testsuite>
    </testsuites>

    <logging>
        <log type='coverage-clover' target='coverage.xml' />
        <log type='coverage-text' target='php://stdout' showOnlySummary='true' />
    </logging>

    <filter>
        <whitelist>
            <directory>../src</directory>
            <exclude>
                <directory>../vendor</directory>
            </exclude>
        </whitelist>
    </filter>
</phpunit>
  • You can see KERNEL_CLASS configured because for some cases you will need own kernel for phpunit.
  • Please add tests/coverage.xml to ignored files.

Now you are ready to run your test suite:

b$ vendor/bin/phpunit -c tests/phpunit.xml

Time for code quality tools

Install:

b$ composer require --dev phpstan/phpstan
b$ composer require --dev sebastian/phpcpd
b$ composer require --dev squizlabs/php_codesniffer
b$ composer require --dev friendsofphp/php-cs-fixer

add php-cs-fixer.config.php, phpstan.neon (optional) and run:

b$ vendor/bin/php-cs-fixer fix --config=tests/php-cs-fixer.config.php --dry-run --diff src tests
b$ vendor/bin/phpcs --report-full --standard=PSR2 src tests
b$ vendor/bin/phpstan analyse --level=4 src -c tests/phpstan.neon
b$ phpdbg -qrr vendor/bin/phpunit -c tests/phpunit.xml

Build? Oh, yes!
