Being Drupal Specialist

Why Need Docker :  Lets suppose we are working in a large application which needs ,Drupal 8 ,PHP7.4, Mysql 8, Redis server, Mongodb,solar server, nodejs server etc. And at the same time I also give maintenace for another project on drupal 7, But it needs some old version of php, mysql,redis etc because it is old project developed 4 year before. So it's too complicated to run both the project in same machine just because of dependencies, Proublem 2 : Lets suppose in local we work on apache & sqlite & on production nginx & mysql, So may be some issue should be raised in production, To handing this type of situation Docker & vergant is much helpfull. How is Docker Different from Vagrant?: Docker :  Docker  is often described as "lightweight," because it simply provides containers within the host machine's Linux operating system. Docker containers hold an application's components, including binaries, libraries, and configurations, as we...

Types of tests: Writing tests All PHP-based tests for Drupal core are written using the industry-standard PHPUnit framework, with Drupal extensions. There are several categories of tests; each has its own purpose, base class, namespace, and directory: Unit tests: Purpose : Test functionality of a class if the Drupal environment (database, settings, etc.) and web browser are not needed for the test, or if the Drupal environment can be replaced by a "mock" object. Base class :   \Drupal\Tests\UnitTestCase Namespace : \Drupal\Tests\yourmodule\Unit (or a subdirectory) Directory location : yourmodule/tests/src/Unit (or a subdirectory) Kernel tests: Purpose : Test functionality of a class if the full Drupal environment and web browser are not needed for the test, but the functionality has significant Drupal dependencies that cannot easily be mocked. Kernel tests can access services, the database, and a minimal mocked file system, and they use an in-memory pseudo-installation. Howe...

NOTE :  it’s extremely important that your development environment is using the same version of PHP that the target production environment will use. Otherwise Composer may download packages that won’t work in production.   (With larger development teams, using something like  Vagrant  or Docker for local development can help ensure compatibility between local development instances and the production stack How do I download modules and themes: 1 - composer require drupal/devel  it would download the module to web/modules/contrib. If you want to change the download destination, you can alter the paths in your composer.json.  Development Dependencies: composer require --dev drupal/devel  For example, since the Devel module shouldn’t be used in a production environment, you may only want it to get downloaded on development environments. With Composer, you can achieve this by passing the --dev flag to the composer require command. This wi...
