For running the Behat tests you will need some additional context.

• The context Testing/Behat is used inside the Behat feature context to boot flow.

By using the FlowEntitiesTrait and tagging the feature with @flowEntities, the doctrine tables will be dropped.

Make sure to create a new database for the Behat tests as otherwise your data will be lost.

Configuration/Testing/Behat/Settings.yaml

Neos:
  Flow:
    persistence:
      backendOptions:
        dbname: 'neos_testing_behat'
        driver: pdo_mysql
        user: ''
        password: ''

Previously when including the FlowContextTrait, and tagging the feature with @fixture, it would clear the doctrine tables after each tests.

The new FlowBootstrapTrait doesn't handle this anymore, but one needs to use the FlowEntitiesTrait and tag the feature with @flowEntities

Previously we advised to install behat into a separate folder via behat:setup, but there is currently no need for this complexity. Now we advise to simply install behat inside the same composer distribution.
