Yii2 acceptance tests. Rollback all changes that were made in acceptance test after each test

Yii 2.0 Testing
1

I need to revert all changes that were made in database by acceptance test after each acceptance test.

As described in Yii2 docs, you should set transaction: false for Yii2 module in acceptance.suite.yml . And you should use cleanup: true and transaction: true for Db module in codeception.yml .

Actual: changes that acceptance test did in database are not reverted.

Expected: changes that acceptance test did in database are reverted.

transaction: true in Db module should wrap all queries that were made in test into transaction and rollback transaction in the end of test.
That works for unit & functional tests but not for acceptance…

What am i doing wrong?
