Adobe AD0-E722 Exam - Topic 1 Question 10 Discussion

Actual exam question for Adobe's AD0-E722 exam
Question #: 10
Topic #: 1
[All AD0-E722 Questions]

An Architect agrees to improve company coding standards and discourage using Helper classes in the code by introducing a new check with PHPCS.

The Architect creates the following:

* A new composer package under the AwesomeAgency\CodingStandard\ namespace

* The ruleset. xml file extending the Magento 2 Coding Standard

What should the Architect do to implement the new code rule?

A)

B)

C)

Show Suggested Answer Hide Answer
Suggested Answer: C

Option C is correct because adjusting the ruleset.xml file with the new rule is the simplest and most effective way to implement the new code rule. The ruleset.xml file defines the coding standards that are applied by PHP_CodeSniffer. By extending the Magento 2 Coding Standard and adding a new rule, the Architect can customize the code analysis and enforce the company coding standards.The new rule can use the Magento2.Namespaces.ForbiddenNamespaces sniff to check for any usage of Helper classes in the code and report them as errors or warnings1.

Option A is incorrect because creating a new composer package under the AwesomeAgencyCodingStandard namespace is not enough to implement the new code rule. The composer package is just a way to distribute and install the coding standard, but it does not define the rules themselves.The Architect still needs to create a ruleset.xml file and register it with PHP_CodeSniffer2.

Option B is incorrect because creating a new class AwesomeAgencyCodingStandardRulesetForbiddenNamespaces and specifying the rule inside the process method is unnecessary and complicated. The Architect does not need to create a new class or a new sniff for this rule, as there is already an existing sniff in the Magento 2 Coding Standard that can be used for this purpose.The Magento2.Namespaces.ForbiddenNamespaces sniff can be configured with an include-pattern element to specify which namespaces are forbidden1.

Wait, are we really ditching Helper classes? That seems extreme.

Helper classes can be useful though, not sure if they should be discouraged entirely.

I vaguely remember something about configuring the ruleset in a specific file, but I’m unsure if it’s in the composer.json or somewhere else.

I think the Architect should run a command to apply the new ruleset, but I can't recall if it's a specific PHPCS command or something else.

This question feels similar to one we practiced about implementing custom rules. I think the key is ensuring the new package is properly autoloaded.

I remember we discussed how to extend coding standards in PHPCS, but I'm not sure if the ruleset needs to be registered in a specific way.

I feel pretty good about this question. The key is understanding how to create a custom PHPCS rule that extends an existing standard and includes the specific logic to check for and discourage the use of Helper classes. I think I can identify the correct approach from the options provided.

This is a tricky one. There are a few different steps involved, and I want to make sure I understand them all before selecting an answer. I'll need to review the options closely and think through the process of implementing a new PHPCS rule.

Okay, I think I've got this. Based on the information provided, it looks like the Architect needs to create a custom PHPCS rule that extends the Magento 2 Coding Standard and includes the logic to discourage the use of Helper classes. I'm pretty confident I can identify the right approach from the options given.

Hmm, I'm a bit unsure about this one. The question mentions creating a new composer package and a ruleset.xml file, but I'm not entirely clear on how those pieces fit together to implement the new code rule. I'll need to think through the details carefully.

But Option A specifically mentions the ruleset.xml file extending the Magento 2 Coding Standard, which seems important for this task.
