public function ValidateMigrationStateTestTrait::testMigrationState in Commerce Migrate 3.0.x

Same name and namespace in other branches

1. 3.1.x modules/ubercart/tests/src/Kernel/Traits/ValidateMigrationStateTestTrait.php \Drupal\Tests\commerce_migrate_ubercart\Kernel\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.
