> Often times, unit tests will invoke TestRunner.run, and then iterate through the output FlowFiles, ensuring that a particular attribute exists, or that an attribute is equal to some value.
> As a convenience, we should provide a mechanism to indicate that all output FlowFiles (or all FlowFiles routed to a given relationship) meet some criteria.
> For example:
> {code}
> TestRunner.assertAllFlowFilesContainAttribute( String attributeName );
> {code}
> {code}
> TestRunner.assertAllFlowFilesContainAttribute( Relationship relationship, String attributeName );
> {code}
> Additionally, we should consider allowing a "callback" mechanism:
> {code}
> TestRunner.assertAllFlowFiles( FlowFileValidator validator );
> {code}
> {code}
> TestRunner.assertAllFlowFiles( Relationship relationship, FlowFileValidator validator );
> {code}
