Magento 2 Certified Professional Developer Exam Experience

M2 Certified Professional Developer test is here for a while now and I finally got some time to prepare and appear for this test. It asks you 60 questions which you have to answer in a time limit of 90 minutes. So basically you get 1.5 minutes to answer each question. Though you should not waste time if you are able to answer the question quicker, as there are many questions in the test which are lengthy and requires more time to understand the question. If you are a non-native English speaker, you may have to read some of the questions 2-3 times before fully understanding what it is exactly asking. Passing score is 64% – so you need to get 39 correct answers out of 60, which is almost 2 out of 3 questions. At the end of the test, you get the score on screen which is great to know instantly if you passed or you need to re-take the test.

Yesterday I took the M2 Professional Developer test and passed it. I found it difficult to be honest, questions were lengthy and answers were confusing. Magento recommends developers to at least have 1.5 to 2 years of experience before taking this test to pass, but I think you can still go for the test if you have worked on 4-5 Magento 2 projects hands on with around a year of experience. I believe that is enough if you are fully into Magento and understand the architecture of the system and technical concepts of various features it offers.

I found SwiftOtter very useful, along with it’s practice test where it offers 44 questions https://swiftotter.com/technical/certifications/magento-2-certified-developer-practice-test. However, it’s not guaranteed that you will pass solely by studying their guide and practice test. You also need to understand the code and should have experience working on it in the M2 projects to clear the exam. I suggest taking the practice test once you have read and understood the topics in the guide and Magento DevDocs and are ready to face the real test.

It’s evident there’s a lot of hard work done by the Magento U team and developers who contributed to this test by writing questions and answers. It’s really hard to pass this test if you don’t have deep understanding in Magento 2 concepts and don’t have enough practical knowledge to prove your M2 abilities.

I think this test could have done even better if it had also focused on:

Security – Not a single question was asked on this topic. I am not talking about Payment, PCI and Magento Vault things when I say Security, I mean writing code that does not leave behind security vulnerabilities. It should be must for a backend or full-stack developer to at least have a basic understanding of how to write secure code, Magento had a great opportunity to include some good security questions (like CSRF token, escaping user-submitted data, XSS prevention, preventing file path exploits, sanitizing user data before saving/getting from db, etc..) here, but….

Readability – Most of the Magento developers are from non-native English speaking countries, myself included. I feel there were few lengthy questions which were just difficult to understand for non-native speakers. I also heard similar complaints from few developers who took this test confirming that they had to read some of the questions 2-3 times which took much of their time to just understand what the questions were trying to ask. That’s a disadvantage to many developers and I believe Magento U will take a note of that when writing upcoming new test questions.

Let me know your thoughts! Kudos to Magento U team for creating such an outstanding test.

Setting up Magento 2.2.3 on Valet+ (requires MacOS)

Wondering what is Valet+? It is a development environment for MacOS. If you have previously used Vagrant and/or Docker, I think you would just love Valet+. Valet+ is very easy yet fast development environment, as it doesn’t require you to edit /etc/hosts, vhosts, mysql, etc.. For more information on Valet+ and how it differs with Valet, please read this: https://github.com/weprovide/valet-plus/blob/master/readme.md

Let me know in comments section which one you prefer out of these 3?

Okay so let’s come to topic and start preparing to install Valet and Magento.

1.) Install Homebrew if you do not have it already on your Mac

2.) Let’s install PHP 7.1

brew install homebrew/php/php71

If you already have php70, you can unlink it before running above command:

brew unlink php70

✩✩✩✩ Extensions ✩✩✩✩

If you are having issues with custom extension compiling, ensure that you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:

PATH="/usr/local/bin:$PATH"

PHP71 Extensions will always be compiled against this PHP. Please install them using --without-homebrew-php to enable compiling against system PHP.

✩✩✩✩ PHP CLI ✩✩✩✩

If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc, ~/.zshrc, ~/.profile or your shell's equivalent configuration file:
export PATH="$(brew --prefix homebrew/php/php71)/bin:$PATH"

✩✩✩✩ FPM ✩✩✩✩

To launch php-fpm on startup:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/php71/homebrew.mxcl.php71.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php71.plist

The control script is located at /usr/local/opt/php71/sbin/php71-fpm

OS X 10.8 and newer come with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:

PATH="/usr/local/sbin:$PATH"

You may also need to edit the plist to use the correct "UserName".

Please note that the plist was called 'homebrew-php.josegonzalez.php71.plist' in old versions of this formula.

With the release of macOS Sierra the Apache module is now not built by default. If you want to build it on your system you have to install php with the --with-httpd option. See brew options php71 for more details.

By 31st March 2018 we will deprecate and archive the PHP tap.
Some of the formulae will be migrated to homebrew-core.

For more details, see https://github.com/Homebrew/homebrew-php/issues/4721

To have launchd start homebrew/php/php71 now and restart at login:
brew services start homebrew/php/php71

Magento 2 upgrade from 2.0.* to latest version using composer via CLI

In this post I will show you how to upgrade Magento 2.0.5 (2.0.*) to 2.1.6 which is latest CE version as of today. We will do it using composer via server command-line interface. It is recommended to take code and DB backup and do this upgrade on your development/stage server first.

Magento 2 comes with Web Setup Wizard (under Admin > System) where you can upgrade from admin panel itself, but for some reason it was always failing for me at Readiness Check’s Component Dependency check.

Step 1.) Edit the composer.json which should be located at the root of your store. Change version and magento/product-community-edition from 2.0.* (whatever you have currently) to 2.1.6 or any latest version you wish to upgrade to. Also change sample data versions from 100.0.* to 100.1.*

Magento 2 hello world module in 2 mins!

Create Magento 2 hello world module in 2 minutes!

To create a simple custom module in Magento2 which will give an output on frontend website from your module, follow below steps:

Change to app/code directory where all the Magento2 module lives. Notice there are no codepools (core, community, local) under this directory like it used to be in Magento 1.x

1
cd app/code

Create your company name directory

1
mkdir Hello

Create you module name directory

1
mkdir Hello/World

Create etc directory to hold module config file

1
mkdir Hello/World/etc

module.xml file is required only to hold module name and it’s version

1
vi Hello/World/etc/module.xml
1
2
3
4
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Hello_World" setup_version="0.1.0" />
</config>

Register your module, this is required in all the modules. Only thing you will change is your module name (Hello_World)

1
vi Hello/World/registration.php
1
2
3
4
5
6
<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Hello_World',
    __DIR__
);

Create frontend directory under etc to define frontend routes. We are creating this because we want to output something on frontend website.

1
mkdir Hello/World/etc/frontend

routes.xml is used to give your module a front name. Only thing you will be interested is tag which holds frontName for the enclosed module name.

1
vi Hello/World/etc/frontend/routes.xml
1

3

8
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
    <router id="standard">
        <route id="first" frontName="first">
            <module name="Hello_World" />
        </route>
    </router>
</config>

Create Controller directory to hold your module’s controller files

1
mkdir Hello/World/Controller

Create your controller directory, this will become part of the url after frontName

1
mkdir Hello/World/Controller/Hello

Create controller file, notice there is no controller action in Magento2 Controller. This will again become part of the url and will call execute() method of the class.

1
vi Hello/World/Controller/Hello/World.php
1
2
3
4
5
6
7
8
9
<?php
namespace Hello\World\Controller\Hello;
class World extends \Magento\Framework\App\Action\Action
{
    public function execute()
    {
        echo 'Hello world!';
    }
}

Change directory to reach Magento 2 root directory

1
cd ../../

Enable your module, so an entry will go to app/etc/config.php file and cache will be cleared

1
bin/magento module:enable Hello_World

This will add your module with it’s current version to DB table setup_module, without running this command you won’t see the changes of newly created module.

1
bin/magento setup:upgrade

Check your module in browser: http://www.yourwebsite.com/first/hello/world. If you have done everything correct, it should output “Hello world!”
