[All AD0-E722 Questions]

An Adobe Commerce Architect needs to create a new customer segment condition to enable admins to specify an Average sales amount' condition for certain segments.

The Architect develops the custom condition under Vendor\Module\Model\Segment\Condition\AverageSalesAmount with all of its requirements:

During testing, the following error appears:

What should the Architect do to fix the problem?

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.

I'm just picturing the Architect staring at the screen, scratching their head and going, 'Wait, what?' Option A is the answer, no doubt about it.

Ah, the joys of debugging custom code. I hope the Architect has a sense of humor, because this error is quite amusing. Option A is the solution, no doubt.

Ah, the good old namespace problem. I bet the Architect forgot to update the class name. Option A is the clear choice here.

Hmm, looks like the Architect needs to fix the namespace issue in the custom condition. Option A seems like the way to go.

Hmm, that's a good point. I see your rationale. Option B might be the better solution after all.
