`@magentoAppArea` annotation REQUIRED for Controllers Integration Tests

[lbajsarowicz]

Rule

Integration Test class should contain

/**
 * @magentoAppArea adminhtml
 */

Reason

This is required annotation to specify the area code for Controllers.
Integration Tests fail when it's missing.

CC: @lenaorobei We've faced issue related to it when fixing PageBuilder tests.

Hi @lbajsarowicz,

From what I see on DevDocs it does not seem to be required https://devdocs.magento.com/guides/v2.3/test/integration/annotations/magento-app-area.html

Could you please provide more context?

[lbajsarowicz]

When Integration Tests are missing @magentoAppArea it's automatically assumed that it's frontend. So if you refer to adminhtml - this causes failure (router is unable to recognize the route).

Doing so helps avoiding the situations that we already had with PageBuilder IntegrationTests during introducing AbstractInterface.
