As i feared the Neos.Neos tests fail because we dont tear down all tables now automagically.

This is because we have to respect the ignore table list in the teardown of behat: neos/behat#37

001 Scenario: Nodes on user workspace have been created                      # Features/AssetUsage/01-NodeCreation/01-CreateNodeAggregateWithNode_WithoutDimensions.feature:64
      Then I expect the AssetUsageService to have the following AssetUsages: # Features/AssetUsage/01-NodeCreation/01-CreateNodeAggregateWithNode_WithoutDimensions.feature:74
        Not all given asset usages where found.
        Failed asserting that an array is empty.

Locally i got 123 failing test.

Following dbal only repos are affected:

• WorkspaceAndRoleRepository
• AssetUsageRepository

I worked around this now by explicitly pruning the repositories again in the tests ... its not pretty but maybe the best.

Its probably legit that the FlowEntitiesTrait does NOT touch these tables anymore as they are dbal pure and not flow entities ^^
