2. 10 core/modules/migrate_drupal/tests/src/Traits/ValidateMigrationStateTestTrait.php \Drupal\Tests\migrate_drupal\Traits\ValidateMigrationStateTestTrait::testMigrationState()

Tests the migration information in .migrate_drupal.yml.

Checks that every discovered pair has a corresponding declaration in the declared pairs. The alternate check, that each declared pair has a corresponding discovered pair is not possible because declarations can be made for the two cases where migrations are yet to be written and where migrations are not needed.
