A Quick Guide to Testing Spring Data Neo4j With NoSQLUnit:
Spring Data Neo4j is the project within Spring Data project which provides an extension to the Spring programming model for writing applications that uses Neo4j as graph database. To write tests using NoSQLUnit for Spring Data Neo4j applications, you do need nothing special apart from considering that Spring Data Neo4j uses a special property called type in graph nodes and relationships which stores the fully qualified classname of that entity.
Is there a BigDataUnit framework? My only requirement is to use XML. Heavily.
