The issue here is that the site breaks every time the users change interface locale in the Admin Panel. This is because the static content for the different locales is not generated during the deployment process. The solution is to adjust the tools build script and specify required locales during *setup:static-content:deploy’ command. This will ensure that the static content for all the needed locales is generated and deployed to the project servers. References: 1

• Option A is correct because enabling the config flag under deployment/blue_green/enabled is one of the steps to ensure zero downtime during the deployment process of Magento 2 on-premises. This flag enables the blue-green deployment feature, which allows deploying a new version of the Magento application to a separate environment (blue) without affecting the current live environment (green). Once the new version is ready, the traffic can be switched from green to blue with minimal or no downtime1.
• Option C is correct because running bin/magento setup:upgrade --keep-generated is another step to ensure zero downtime during the deployment process of Magento 2 on-premises. This command updates the database schema and data without deleting the generated code and static view files. This way, the Magento application can still serve requests from the cache while the database is being upgraded2.
• Option B is incorrect because running bin/magento setup:upgrade --dry-run=true does not upgrade the database, but only checks if there are any errors or conflicts in the database schema or data. This command can be used for testing purposes, but it does not affect the deployment process or the downtime3.
• Option D is incorrect because there is no such option as --convert-old-scripts-true for the bin/magento setup:upgrade command. This option does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.
• Option E is incorrect because there is no such config flag as developer/zero_down_time/enabled in Magento 2. This flag does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.

To create an integration test that executes different logic in different store views, the Architect needs to do the following steps:

• Create one test class that extends \Magento\TestFramework\TestCase\AbstractController or \Magento\TestFramework\TestCase\AbstractBackendController, depending on the type of controller being tested1.
• Create one test method that uses the @magentoDataFixture annotation to specify the data fixture file that creates the product2.
• Use the \Magento\TestFramework\Store\ExecuteInStoreContext class to execute the fixture and the tested logic in different store views. This class has a method called executeInStoreContext, which takes two parameters: the store ID and a callable function. The callable function will be executed in the context of the given store ID, and then the original store ID will be restored3. For example:

PHPAI-generated code. Review and use carefully. More info on FAQ.

public function testSomeLogic()

{

// Get the product from the fixture

$product = $this->getProduct();

// Get the ExecuteInStoreContext instance from the object manager

$executeInStoreContext = $this->_objectManager->get(\Magento\TestFramework\Store\ExecuteInStoreContext::class);

// Execute the fixture in store view 3

$executeInStoreContext->executeInStoreContext(3, function () use ($product) {

// Do some operations on the product in store view 3

});

// Execute the tested logic in store view 4

$result = $executeInStoreContext->executeInStoreContext(4, function () use ($product) {

// Call the tested logic on the product in store view 4

return $this->someLogic->execute($product);

});

// Assert that the result is true

$this->assertTrue($result);

}

• 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 AwesomeAgency\CodingStandard\ 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 \AwesomeAgency\CodingStandard\Ruleset\ForbiddenNamespaces 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.

The issue is that the export file is not shown in the list of generated files. This is because the export path is not set correctly. The solution is to execute the command config:set export/customr/files_directory /var/releases/{release_nunber} to set the new export path. This will ensure that the export file is saved in the correct directory and can be accessed from the Admin Panel. References: 1

The issue here is that the product price changes are not reflected on the storefront, even though the indexes are set to update by schedule and there are no items in the backlog. This indicates that there might be some problem with the changelog and indexing process, which are responsible for tracking and applying the data changes to the index tables. Therefore, the Architect should recommend the developer to check if any custom or third-party modules interfere with the changelog and indexing process, and disable or fix them if needed. Additionally, the Architect should recommend the developer to verify that the version_id for the price indexer in the mview_state table is consistent with the last entry for the same column in the changelog table, and re-synchronize them if they are out of sync. This will ensure that the indexer can process all the data changes correctly and update the index tables accordingly. References: admin/systems/tools/index-management.html?lang=en#cron-groups-and-processes1 2

To make sure the vcl_hash function of Varnish considers the newly created attribute, the Architect needs to do the following steps:

• Create a new class that implements the Magento\GraphQlCache\Model\CacheId\CacheIdFactorProviderInterface interface. This interface defines two methods: getFactorName and getFactorValue. The getFactorName method should return the name of the attribute, in this case, my_attribute. The getFactorValue method should return the value of the attribute for the current customer, which can be obtained from the customer session or customer repository1.
• Add this class to the idFactorProviders array of Magento\GraphQlCache\Model\CacheId\CacheIdCalculator through dependency injection. The CacheIdCalculator is responsible for generating a cache ID for each GraphQL request based on the factors provided by the idFactorProviders. By adding the new class to this array, the Architect ensures that the cache ID will include the value of my_attribute1.
• The cache ID is then used by Varnish to hash and lookup the cached response for each request. By including my_attribute in the cache ID, the Architect ensures that Varnish will serve different responses based on the attribute value of the customer2. References:

The magento-vars.php file is used to set the website or store view based on the HTTP host, but it does not affect GraphQL requests. GraphQL requests are handled by a separate controller that does not use the magento-vars.php file. Instead, GraphQL requests use the default store view of the default website, unless a store header or store cookie is provided in the request. The store header or cookie should contain the store code of the desired store view. For example, to query data from website_two, the request should include a header like store: store_two or a cookie like store=store_two12. References:

The product price index can be optimized by using parallel mode and customer group merging. Parallel mode allows the indexer to run multiple threads simultaneously, which can speed up the indexing process. Customer group merging reduces the number of rows in the price index table by merging customer groups that have the same product prices. This can improve the performance of the price index queries and reduce the index size. References: Indexing optimization, Price index customer group merging

The issue here is that the database storage is not being fully cleaned after the test is run. The solution is to modify the method PHPDoc and change the annotation @magentoDbIsolation to enabled. This will ensure that the database storage is fully cleaned after the test is run. References: 1

The issue is being caused by the high coupling between objects (CBO) value of the class MyService. CBO is a metric that measures the number of classes that are coupled to a given class, either by method calls, property or parameter references, inheritance, or constants1. A high CBO value indicates that the class is too tightly coupled with other classes, which makes it more difficult to maintain, test, and reuse2. To reduce the CBO value, the Architect should introduce a new class that encapsulates the five scalar parameters that configure the behavior of MyService. This way, the constructor of MyService will only have one parameter of the new class type, instead of five scalar parameters. This will also make the code more readable and maintainable, as the new class can provide methods to access and manipulate the configuration data. The constants referencing other classes should not be consolidated into a string representation, as this would not reduce the CBO value and would make the code less clear and type-safe3. The number of different classes and interfaces referenced anywhere inside the class is not relevant for the CBO metric, as it only counts the classes that are coupled to the given class1. References: CBO coupling between object, Coupling Between Object classes (CBO), Cohesion and coupling of an object in OO programming

Developer mode is the best option for setting up a development environment for testing functionality, not performance, before being passed to the testing team. In developer mode:

• Errors are logged and hidden from the user. This ensures that the user does not see any uncaught exceptions or debugging information, but the developers can still access them from the log files.
• Cache mode can only be changed from command line. This prevents any accidental or unauthorized changes to the cache settings from the admin panel or other sources.
• Static files are created dynamically and then cached. This allows the developers to see the latest changes to the static files without having to run the static content deployment command every time. The static files are also cached for faster loading.

According to the Adobe Commerce documentation, the best way to add a custom tax calculation to all orders is to declare a new total collector in the “etc/sales.xml” file of a custom module. This way, the custom tax logic can be implemented in a separate class that extends the \Magento\Quote\Model\Quote\Address\Total\AbstractTotal class and overrides the collect() and fetch() methods. The collect() method is responsible for calculating the tax amount and adding it to the quote address, while the fetch() method is responsible for displaying the tax amount in the cart and checkout pages. The new total collector can be assigned to any area of the order totals, such as before or after the subtotal, shipping, or grand total.

According to the Adobe Commerce documentation, to create a new xml configuration file, the Architect needs to create a Data class and a Reader class for the custom module. The Data class is responsible for storing and retrieving the configuration data from the cache or the Reader class. The Data class should implement the “\Magento\Framework\Config\Data” interface or extend the “\Magento\Framework\Config\Data” class. The Reader class is responsible for reading and validating the xml configuration files from the file system. The Reader class should implement the '\Magento\Framework\Config\Reader\Filesystem" interface or extend the '\Magento\Framework\Config\Reader\Filesystem" class. The Architect also needs to declare the Data class and the Reader class in the di.xml file of the custom module, and specify the name of the xml configuration file, the converter class, and the schema locator class for the Reader class.
