TYPO3 Core

the test belongs to the DisjunctionValidator, that delivers validation connected by OR and returns true as soon as one validator out of the collection returns true.
The test ensured that all validators are called, even if one returned true already.
The skip message contains a hint about a needed bugfix in Flow.

As it seems a waste of resources to call methods that can not change the result of the overall operation anymore, and Flow is not the leading system for extbase development anymore, so no compatibility has to be observed, the formerly skipped test can savely be removed.
