Dependency Injection
Service Contracts
Unit Testing
Integration Tests
Functional Tests

16. Mage::getModel() et al
Dependency
Injection

17. class SingletonExample
{
protected $singleton;
public function __construct(
Singleton $singleton
) {
$this->singleton = $singleton;
}
}
$objectManager->get('FoomanDiExamplesModelSingleton');
behind the scenes:

18. class ModelExample
{
protected $model;
public function __construct(
Model $model
) {
$this->model = $model;
}
}
$objectManager->create('FoomanDiExamplesModelModel');
behind the scenes:

19. class ModelExample
{
protected $model;
public function __construct(
Model $model
) {
$this->model = $model;
}
}
$objectManager->create('FoomanDiExamplesModelModel');
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

behind the scenes:

20. Executive Summary Dependency Injection
• Constructor based with Magento flavour
• di.xml
• Use Interfaces wherever possible
• Don’t use the ObjectManager directly

22. Create your Service Contracts
with 2 Ingredients

23. Magento 1.0
0 Unit Tests
0 Integration Tests
0 Functional Tests
Magento 2.0
15K Unit Tests
3.5K Integration Tests
300 Functional Test Scenarios

24. Unit Testing

25. Integration Tests

28. public function testAclHasAccess()
{

43. 3. Learning with the Community
Composer + Semantic Versioning
PSR-X
Get involved

44. PHP is growing up too

45. Composer
+
Semantic Versioning
=
Love

46. My Version N

47. My Version N+1

48. PSR-X
Don’t be the IE of developers
php-cs-fixer fix --level=psr2 .

49. Best way to keep learning?

50. Get involved!

51. magento.stackexchange.com

52. Open source some code

53. 1. Growing Up
Invest in yourself
2. Learning from Magento
Dependency Injection
Use and create your own Service Contracts
Leverage Test Frameworks
